Mechanoreceptors present in human skin are involved in tactile sensation. Where are the cell bodies of these mechanoreceptors located?
A)in the brain B)in ganglia near the spinal cord C)in the spinal cord D)in the dermal layer of the skin near the sensory endings of the mechanoreceptors
Diagram A below shows a stimulus applied to a sensory cell, and diagram B is the pattern of action potentials generated in response. This pattern of action potentials:
A)permits discrimination between different kinds of stimuli. B)improves the simultaneous detection of two kinds of stimuli-for example, smell and taste. C)allows an animal to constantly measure the strength of a continuing input. D)allows an animal to detect the onset of a new stimulus. /12
