1

Dual innervations

Sympathetic and parasympathetic division of ANS

2

Ganglion

Lump of nerve cell bodies

3

Sympathetic division

Mobilizes fight or flight

4

Parasympathetic division

Rest and digest

5

Autonomic ganglion

Cluster of nerve cell bodies

6

Cholinergic neurons

Nerve cell mainly using Neurotransmitter acetylcholine

7

Adrenergic neurons

Secretes norepinephrine

8

Agonist

Chemical binding to receptors to activate it

9

Antagonist

Substance interfering or inhibiting physiological receptor

10

11

Interceptors

Sensory receptor receiving stimuli from within the body
