Voluntary PNSmade up of voluntary

SOMATIC nerves- a.k.a. voluntary SENSORY & MOTOR neurons

under CONSCIOUS control

how you relate with the EXTERNAL environment

Page 4: PNS PERIPHERAL NERVOUS SYSTEM

Involuntary PNS also called the Autonomic Nervous System

(the ANS) made up of autonomic (“automatic”)

nerves to your internal glands & organs (heart, lung, liver, etc.)

Unconcious divided into the:

1. SYMPATHETIC NERVOUS SYSTEM=stress system! “fight or flight”!=adrenaline!

2. PARASYMPATHETIC NERVOUS SYSTEM=think PARAmedic keeping you normal / at homeostasis=“rest & digest”

PNS: SENSORY RECEPTORS

highly modified structures on the dendrites of sensory neurons

Examples skin receptors: pain, temp., pressure, etc.

(see handout) nose (called olfactory receptors) tongue (“tastebuds”) *eyes: photoreceptors *ears: hearing & balance receptors
