A
maintaining a constant internal environment
2
Q
stimulus
A
change in environment
3
Q
receptors
A
cells detecting stimuli
4
Q
effectors
A
muscles or glands bringing about a response to stimuli
5
Q

A
spin + brain, coordinates effectors’ response
6
Q
peripheral system
A
connects central nervous system with rest of body
7
Q
sensory neuron
A
carries electrical impulses from receptors to central nervous system
8
Q
motor neuron
A
carries electrical impulses from central nervous system to effectors
9

reflex
A
protective reactions to stimuli
10
Q
arc
A
pathway controlling reflex action
11
Q
connecting neuron
A
carries impulse from sensory to motor neuron
