somatosensory input

Question 1

slowly adapting neurons

Answer 1

continuous information to CNS while terminal deformed

Question 2

rapidly adapting neurons

Answer 2

-detects changes in stimulus strength
-number of impulses proportional to rate of change of stimulus

Question 3

Meissner’s corpuscles (cutaneous receptor)

Answer 3

abundant in skin locations where two point discrimination is highest; not present in hairy skin

Question 4

merkel’s discs

Answer 4

cutaneous receptor
-distribution as for Meissner’s corpuscles, but also present in moderate numbers in hairy skin

Question 5

which cutaneous receptor

Answer 5

pacinian corpuscle
(within dermis and fascia)

Question 6

which cutaneous receptor

Answer 6

Ruffini endings
(within dermis and also joint capsules)

Question 7

which cutaneous receptor

Answer 7

merkel cells

Question 8

which cutaneous receptor

Answer 8

meissner corpuscle

Question 9

which part of the dorsal column does sensory input to T6 and below travel through

Answer 9

fasciculus gracilis

Question 10

what is the dorsal column medial lemniscal pathway

Answer 10

major route by which touch and proprioceptive information ascends to the cerebral cortex

Question 11

where is the somatosensory cortex located

Answer 11

the post central gyrus of the parietal lobe immediately posterior to central sulcus and adjacent to posterior parietal cortex
