Question 3

Peripheral Nervous System Input

Answer 3

In general, there are two different ways that sensory information is conveyed to the central nervous system.

1) In some cases, such as the odorant receptor cells of the
nose, an afferent neuron has a specialized ending that produces graded potentials that can lead to action potentials in response to a stimulus.

2) In other systems such as vision, taste, and hearing, a specialized receptor cell produces graded potentials that can trigger an action potential in an afferent neuron. Each afferent neuron receives signals from a single type of stimulus.
