Question

Please help with these questions; no need to explain either. Thank you!!

Which is/are true about the peripheral somatosensory system?
a. receptive fields are usually large where fine analysis is required (like finger tips).

b. receptor cells are best at distinguishing two or more simultaneous stimuli when the stimuli are within the cell’s receptive field.

c. receptive fields are arranged systematically on the sensory surface.

d. A and B

e. B and C

True or false: A topographical representation of the body is established at the sensory surface and preserved in the spinal cord and all ascending somatosensory structures including the cortex.

Which of the following is/are TRUE about “two-point discrimination” on the body surface?
a. The two-point discrimination procedure is a good way of measuring receptive field size.

b. It shows that receptive fields are roughly the same size all over the body surface.

c. It shows that two points of stimulation are detectable within a given receptive field.

d. a and b.

e. All of the above.
