Flashcards in Chapter 15 part One Deck (18):
1

Dual innervation

Organ receives innervation from both sympatheric and parasympathetic neurons

2

Glands, smooth & cardiac muscles

effectors in the ANS

3

Preganglionic Neuron

Myelinated motor neuron in ANS that projects from the CNS to the sympathetic ganglion

4

Postganglionic Neuron

Motor neuron in the ANS that projects from the sympathetic ganglion to the effector

5

Hypothalamus

Integration center of the ANS

6

Interoceptors

Receptors in the ANS, detect chemistry, stretch pressure

7

Adrenergic Neuron

Produces the neurotransmitter epinephrine & norepinephrine

8

Cholinergic Neuron

Produces the Neurotransmitter acetylcholine (Ach)

9

Use neurotransmitter acetylcholine

Sympathetic postganglionic neurons (except to sweat glans)

10

Adrenal Medulla

Modified sympathetic postganglionic neuron; secretes norepinephrine to the blood

11

Muscarinic & nicotinic receptors

Bind the neurotransmitter acetylcholine (ach)

12

Alpha & beta receptors

Bind the neurotransmitter norepinephrine

13

Sympathetic Preganglionic neurons

Secrete Ach to postganglionic neuron in the prevertebral & sympathic chain ganglia

14

Parasympathetic Preganglionic neuron

Secrete Ach to postganglionic neurons in terminal ganglia & ganglia on cranial nerves

15

Sympathetic postganglionic neurons

Secrete norepinephrine except to sweat glands

16

Parasympathetic postganglionic neurons

Secrete Ach to effectors

17

Parasympathetic nervous system

"rest & digest" craniosacral outflow

18

Sympathetic nervous system

"Fight or flight" thoracolumbar outflow
