Nervous System and the Senses Trivia Questions

1. The corpse coliseum is a collection of nerve fibers that connects the two cerebral hemispheres. What should replace 'corpse coliseum' to make sense of this statement?

From Quiz
Neuroscientific Nonsense

Answer: Corpus callosum

Corpus callosum is the correct term for the bundle of nerve fibers in question. It is shaped like the letter 'C', and found just beneath the cerebral cortex. The four main parts of the corpus callosum, nerve tracts that connect the two hemispheres of the brain, are the rostrum, genu, trunk, and splenium. The term corpus callosum has its origins in Latin terms for 'body' and tough'.

2. Caffeine is classified as what type of substance?

From Quiz This is Your Brain on Caffeine

Answer: Stimulant

Stimulants are a class of drugs which, broadly speaking, make you feel more alert by increasing heart rate, blood pressure, breathing and blood glucose levels. Other stimulants include amphetamines, cocaine and ecstasy.

3. Most people judge the beauty of a person's face by the proportionality of the flappy ears attached to the side of the head. What is the technical name for these flappy pieces of tissue making up the visible ear?

From Quiz I "EAR" you "NOSE" something!

Answer: Auricles

The human ear includes the outer ear, the middle ear, and the inner ear. The outer ear is comprised of the fleshy tissue called the pinna or auricle. The auricle is made up of a single piece of fibrocartilage. The earlobe has a tremendous potential for elasticity. Daryl Belmares, a pastor in Austin Texas claimed to have the world's largest stretched earlobes at a whopping 5.5 inches.

4. In its unexcited state, the cell membrane exists at what is called a resting potential. What does this mean?

From Quiz Nerve Impulses and Neurotoxins

Answer: There is a separation of charge maintained across the membrane

The membrane of a cell is made of a phospholipid bilayer and several proteins which are embedded in this bilayer. When discussing nerve potentials, it is appropriate to refer to the membrane in terms of electrical circuitry. Either side of the membrane, there are varying concentrations of both positive and negative ions, giving a difference in charge (a voltage) across the membrane. The phospholipid bilayer is impermeable to such ions and so maintains this voltage (i.e. it behaves as a capacitor). The proteins may open upon stimulation (either by a ligand or a change in the voltage) and allow ions (charge) to flow. These proteins are therefore the electrical switches in this analogy.

5. We'll start on top of the brain. What is the huge mass at the top of the brain (which most people consider the brain)?

From Quiz Brains

Answer: cerebrum

The cerebrum is the large gray mass that controls learning, reasoning, and memory. It is the largest and most developed part of the brain and is the top end of the human nervous system.

6. Which part of the body is associated with a deviated septum?

From Quiz Eyes, Ears, Mouth, Nose

Answer: nose

The septum is the part of the nose that separates the right and left nasal cavities. While a normal septum is centered between the two and divides them equally, a deviated septum is when the septum is not centered. This causes one of the cavities to be larger than the other. It's frequently caused by some type of trauma to the nose such as a punch or other blow.

7. At rest, neurones must maintain a constant potential difference across their membranes. This is done by establishing a concentration gradient of ions. Which part of the plasma membrane is impermeable to ions, thus helping to maintain this gradient?

From Quiz Nerve Impulses: Getting From A to B

Answer: The phospholipid bilayer

Ions, being polar, cannot freely diffuse through the non-polar phospholipid bilayer. The resting potential (around -70 millivolts) is established by the Na+/K+ ATPase pump, which moves three sodium ions out of the cell and two potassium ions into the cell.

8. The facial nerve arises from the junction of the pons and medulla oblongata in the brainstem. Which cranial nerve is it?

From Quiz The Course and Distribution of the Facial Nerve

Answer: VII

The facial nerve is the seventh of twelve cranial nerves, all of which arise from the brainstem. It is actually the motor branch that emerges from the pontomedullary junction. The nerve of Wrisberg, also called nervus intermedius, arises at this same point between the facial and vestibulocochlear (VIII) nerves and gives rise to the sensory branch of the facial nerve.

9. Why does a scratch relieve an itch?

From Quiz Scratch and Sniff

Answer: No one really knows for sure.

Scratching an itch is instinctive, but no one really knows for sure why scratching an itch makes it go away. There are many theories about the "itch-scratch cycle". One theory is that the discomfort of the scratch distracts the brain from the discomfort of the itch. Another theory suggests that by scratching an itch, one stimulates the large nerves, thus blocking the small nerves causing the itch. A different theory altogether proposes that inhibitory neurons are stimulated during the scratch, and that these neurons cause relief.

10. A sneeze is the body's way to remove irritants and toxins from the nose. What is the rarely used but interesting medical term for a sneeze?

From Quiz The Sneeze: Fact or Fiction

Answer: Sternutation

A sneeze is an involuntary expulsion of air through the nose and mouth. Each sneeze can produce tens of thousands of droplets which can travel up to 2-3 meters! Humans actually expel more from their mouths than their noses during a sneeze.

11. A 30 year old man comes into your office complaining of drooping and not being able to move his lower face. Where is the lesion most likely to be?

From Quiz Clinical Neurology

Answer: Cerebral Cortex

A lesion in the seventh cranial nerve would affect both upper and lower face and would be known as "Bell's Palsy." Since the upper face has dual innervation from the cortex from both sides of the brain, a lesion on one side of the brain would be compensated for by the other. The lower face does not have this dual innervation, so a cerebral cortex lesion would affect it.

12. Which K is a sign of meningitis or meningeal irritation?

From Quiz A-Z of Neurology Part II

Answer: Kernig's sign

A tricky one to start with. Kernig's sign is when there is resistance to full extension of the leg at the knee, when the hip is flexed. Russian physician Vladimir Kernig first described the sign in 1882. Kehr's sign is pain referred to the left shoulder indicating abdominal trauma or irritation. Klumpke paralysis (also called Klumpke-Dejerine paralysis) is caused by an avulsion of C8 and T1 (the eighth cervical and first thoracic vertebrae). It is manifested by loss of function in the small muscles of the hand and the long finger flexors and extensors. Krause's corpuscle is a somatic sensory nerve ending in the skin.

13. A is for what part of the neurone that carries impulses away from the cell body?

From Quiz A-Z of Neurology Part 1.

Answer: Axon

Axons are usually coated in a white fatty substance called the myelin sheath which helps to speed the passage of impulses. They are sometimes called axones. An aqueduct is a canal or passage. There are two in the brain: the Sylvian aqueduct and the Cerebral aqueduct. The arachnoid is the delicate middle layer of the meninges. Its fine web-like appearance gives rise to its name. An aneurysm is a sac formed by a dilation in a vessel wall, usually an artery.

14. Ok, we will start with a question regarding action potentials first. What accounts for the rising phase of an action potential in a typical neuron?

From Quiz Basic Neurobiology

Answer: Influx of sodium (Na+) ions into the neuron

At resting potential the concentration of potassium is high inside the cell and the concentration of sodium is low. The opposite is true for the outside of the cell, sodium concentration is high and potassium is low. When the cell membrane becomes depolarized, sodium channels are opened and this allows sodium ions to flow across the cell membrane causing the membrane potential of the neuron to go past the threshold, or become more positive, and fire an action potential. The rising phase of this action potential is due to the increasing sodium concentration inside of the cell.

15. What loosely defined collection of structures is believed to be the seat of human emotion?

From Quiz The Big Fat Brain Anatomy Quiz

Answer: The limbic system

The limbic system is loosely defined and contains such structures as the hippocampus and the amygdala, along with many others.

16. What can the area of the brain known as the hindbrain also be referred to as?

From Quiz The Human Brain Quiz

Answer: Rhombencephalon

Your hindbrain contains all of the parts that control vital body functions.

17. Branches of which cranial nerve are typically contained within the mucosa of the middle ear space?

From Quiz Cranial Nerve Anatomy

Answer: Glossopharyngeal Nerve

Hmm. . . A little tricky. The facial nerve canal (fallopian canal) is contained within the bone defining the middle ear space and is sometimes (about 25%) dehiscent, however, this is not typical. The nerve to the stapedius also isn't contained in the middle ear, it enters the muscle through a bony canal in the temporal bone. The facial nerve gives sensation to the tympanic membrane's EXTERNAL surface so that doesn't work either. Finally, the chorda tympani courses through the actual middle ear space and, although passing through the mucosa on its way out, is not contained within the mucosa for a substantial distance. The vestibulocochlear nerve doesn't have branches in the middle ear space. The vagus nerve, similar to the facial nerve, gives sensation to part of the EXTERNAL surface of the tympanic membrane and external auditory canal, but not the middle ear space. Note that the trigeminal nerve also contributes to EXTERNAL tympanic membrane sensation. The glossopharyngeal nerve provides sensation to the INTERNAL surface of the tympanic membrane, and has parasympathetic efferent fibers contained in the mucosa that course over the promontory of the middle ear space to eventually supply secretomotor fibers to the parotid gland (Jacobsen's nerve). Extra credit: Which nerve(s) supplies sensation and secretomotor innervation to the mucosa of the middle ear space?

18. Where is the cerebellum located?

From Quiz Biological Aspects of Psychology

Answer: hindbrain

The cerebellum is vital in the role of normal speech.

19. The word "synaesthesia" is derived from which ancient language?

From Quiz The Mystery of Synaesthesia

Answer: Greek

The word "Synaesthesia" comes directly from the Greek (syn-) "union", and  (aísthesis) "sensation", thus meaning something akin to "a union of the senses".  "Synaesthesia" is the British English spelling of the word; in American English, it is often spelled "Synesthesia", without the "a". 

20. Which two parts of the brain are divided by the tentorium cerebelli?

From Quiz Neurology and Psychiatry

Answer: The cerebellum and the occipital lobe

The cerebellum and the occipital lobe of the cerebrum are divided by the tentorium cerebelli. The left and right cerebral hemisphere are connected via the corpus callosum and divided by the fissura longitudinalis cerebri. The pons and the medulla are both structures within the brain stem. Roughly it can be said that the brain stem and the cerebellum are divided by the aquaeductus mesencephali, tectum mesencephalicum and canalis centralis.

21. What is the connective tissue around an individual axon called?

From Quiz The Nervous System 101

Answer: Endoneurium

Perineurium is the covering around a group of axons. Epineurium is the covering around the entire nerve.

22. Which type of pain generally has the shortest duration?

From Quiz It PAINS Me

Answer: acute pain

Acute pain generally lasts from a few days to a few weeks. If pain is still felt after three to six months, it is classed as chronic.

23. Where is the cerebrospinal fluid (CSF) secreted?

From Quiz Human Neuroanatomy

Answer: Choroid plexus

CSF is secreted from the choroid plexus (in the lateral ventricles) and reabsorbed at the arachnoid granulations.

24. What are the two parts of the nervous system?

From Quiz The Nervous System

Answer: Central and peripheral

The central nervous system consists of the brain and spinal cord. The peripheral nervous system includes the 12 pairs of cranial nerves and the 31 pairs of spinal nerves plus their branches.

25. What is the name of the tract that carries motor information down the spinal cord and into the body?

From Quiz Neurobiology

Answer: corticospinal tract

26. A fast adapting receptor is:

From Quiz Advanced Neuorobiology

Answer: Pacinican Corpuscles

Pacinian corpuscles, Meisner's corpuscles and hair follicles are fast adapting receptors in the skin. Merkel's and Ruffini's adapt slowly.

27. How many pairs of major nerves originate in the brain and are known as cranial nerves?

From Quiz The Cranial Nerves

Answer: 12

These twelve nerves originate in the brain, before they split into pairs and pass through apertures in the skull, called foramina. Cranial nerves provide for vision, hearing, balance, smell, taste, tactile sensations of the head, neck, ears, throat and larynx. They also control the muscles of the face, eyes, tongue, and neck areas.

28. The peripheral lobe is involved with the reception and processing of sensory information. 'Peripheral lobe' is nonsense - what is the actual lobe involved with processing sensory information?

From Quiz Neuroscientific Nonsense

Answer: Parietal lobe

The parietal lobe is part of the brain's cerebrum. It is one of the four major lobes of the cerebral cortex in mammals' brains. The parietal lobe is crucial for integrating sensory information and providing animals with spatial orientation. Parietal comes from the Latin word "paries" or "pariet-" for 'wall'.

29. The physical effects of caffeine are due to the way the caffeine molecule reacts with neurochemicals in the brain. Which neurotransmitter, known to promote sleep and suppress arousal, has a similar molecular structure to caffeine?

From Quiz This is Your Brain on Caffeine

Answer: Adenosine

Adenosine is one of the neurotransmitters responsible for making us sleepy. Because caffeine has a similar molecular structure (i.e. shape), it is able to bind to the adenosine receptors in the brain. By stopping the adenosine reaching our brain, coffee keeps us alert and stops us getting sleepy. The downside is that the brain fights back by making more adenosine receptors, which means more caffeine is needed to block the adenosine from getting through. This can cause regular coffee drinkers to build up a tolerance to caffeine, which means they need more coffee to keep them alert.

30. What is the most prominent type of neuronal cell in the central nervous system (CNS)?

From Quiz Diseases & Workings of the Central Nervous System

Answer: Pyramidal cells

Pyramidal cells account for 70% of cells in the CNS, while interneurons are more local and serve to enhance or inhibit pyramidal cells. Astrocytes are similar to interneurons, and blood cells are found everywhere in the body - not just the CNS.
