Quiz Answer Key and Fun Facts

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

Answer: Choroid plexus

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

2. Which cells myelinate axons in the central nervous system?

Answer: Oligodendrocytes

Unlike Schwann cells in the periphery, oligodendrocytes myelinate many axons.

3. Which of these nuclei is not considered functionally part of the basal ganglia (corpus striatum)?

Answer: Amygdala

The amygdala is part of the limbic system, concerned with memory and emotion. The basal ganglia are a group of nuclei involved in motor function.

4. Which is the first nucleus to receive binaural input?

Answer: Superior Olive

The superior olive is therefore a key site of integration of information from both ears, and is involved in localising sounds.

5. Where is the first nucleus to receive binaural input located?

Answer: Medulla Oblongata

6. The pyramidal (corticospinal) tract decussates at the junction between...

Answer: the medulla and the spinal cord

The brain controls most of the body contralaterally, and most fibres cross in the medulla. The pyramidal tract is the major motor pathway.

7. Which of these structures is associated mainly with memory?

Answer: Hippocampus

The hippocampus is part of the limbic system.

8. Which of these nuclei is involved in processing of vision?

Answer: Lateral Geniculate Nucleus

The lateral geniculate nucleus is the only place fibres synapse between the retina and the primary visual cortex.

9. What does the abbreviation GABA stand for?

Answer: gamma-aminobutyric acid

GABA is a common inhibitory neurotransmitter.

10. Which of these structures is part of the rhombencephalon?

Answer: Pons

The rhombencephalon, or hindbrain, consists of the medulla, pons and cerebellum.
