Special Sub-Topic: Advanced Neuorobiology
|A fast adapting receptor is:|
Pacinican Corpuscles. Pacinian corpuscles, Meisner's corpuscles and hair follicles are fast adapting receptors in the skin. Merkel's and Ruffini's adapt slowly.
|The dorsal column in the spinal cord becomes the what in the medulla:|
|The medial lemniscus ascends and synapses in what structure in the brain?|
VPL of the thalamus. The VPL is the third synapse in this pathway.
|The dorsal column pathway carries what types of information to the spinal cord and brain?|
2-point discrimination. It also carries pressure sensations
|What information does the anterolateral system pathway carry?|
tickle and itch. It also carries fast and slow pain, and non-discriminative touch.
|What is the slow pain pathway?|
paleospinothalamic. This carries slow pain to the thalamus, which is basically the dull, aching non-localized pain.
|What fibers carry pain?|
|Which of the following is a misplaced nucleus in the brain?|
mesencephalic nucleus of 5. It is a misplaced nucleus because it is a peripheral nervous system nucleus found in the central nervous system
|If there was a spinal cord lesion at L1 in the anterolateral spinal cord, where would the symptoms manifest?|
at L3 and below on the contralateral side. The ALS pathway crosses over to the opposite side of the spinal cord in the anterior white commissure 2 segments above where the specific axon enters
|If you damaged your cerebellum, which symptoms might you experience?|
dizziness or vertigo. The cerebellum controls balance and this is affected in injury.
