The Role of Peripheral Nerves
The peripheral nervous system (PNS) is one of the 2 main parts of the body’s nervous system and has 2 main subsystems – the somatic, responsible for voluntary actions, and the autonomic, responsible for involuntary actions. These 2 subsystems have 3 main functions – senses, movement, and unconscious processes.
Sensory functions include pressure, touch, temperature, pain, and location, while movement includes stability, mobility, and fine motor control. Thirdly, peripheral nerves deliver signals to the brain to control vital, unconscious processes such as breathing, heartbeat, and glandular stimulation.
