Q
Stimulus

5
Q
Central Nervous System
CNS
A
Sends electrical impluses around the body
Brain + Spine
6
Q
Peripheral System
A
Feeds information to brain from senses
Nerves
7
Q
Receptors
A
Sense change
Stimulus
8
Q
Sensory Neruons
A
Send signal to CNS
Afferent
9
Q
Effectors
A
Response to stimulus
10
Q
