Understanding the Peripheral Nervous System: Structure and Functions

The video introduces the peripheral nervous system (PNS), detailing its structure and function. It explains the roles of sensory and motor neurons in the reflex arc and describes the PNS's divisions: somatic for voluntary actions and autonomic for involuntary actions. The autonomic system is further divided into sympathetic and parasympathetic systems, which manage the body's fight-or-flight and rest-and-digest responses, respectively.
