- Parasympathetic NS
6

Skeletal Muscle Movement
11

A
- Unconscious
- Involuntary
- Visceral Muscle Movement
12
Q
Process of the somatic NS ( not really part of the diagram )
A
- Sensory Neurons
- Brain
- Sensory Neurons
13
Q
step 1: Sensory Neurons
A
- Detects stimuli
- Info sent via PNS to spinal cord
- Sent via afferent track to the brain
SIGNAL : body to brain
14
Q
step 2: Brain
A
- Coordinates a response
- Sends signal to spinal cord & specific body part via efferent tract
SIGNAL : brain to body
15
Q
step 3: Motor Neurons
A
Coordinates movement of body part
