Identify the four main divisions of the peripheral nervous system and explain each one’s function.

The Four main divisions of the Peripheral Nervous system are:

1) Somatic sensory system- They are spread throughout the whole body (means present everywhere inside us), and deals with touch, pain, vibration, pressure, temperature, proprioception, hearing, balance and vision.

2) Somatic motor system - It's main function is to deal with voluntary skeletal muscle contractions.

3) Visceral sensory system - It's main function is to deal with stretching, pain, temperature, nausea, hunger, taste and smell.

4) Visceral motor system - They deal with the involuntary contraction of smooth and cardiac muscle.

Hope this helps!
