Front 1

SNS (sympathetic nervous system) primary preganglionic NT =

Back 1

Acetylcholine (Ach) (cholinergic)

Front 2

SNS primary postganglionic NT=

Back 2

Norepinephrine (NE)

Front 3

In the SNS, Ach is the primary preganglionic NT and binds to the _____ receptor.

Back 3

nicotinic

Front 4

In the SNS, NE is the primary postganglionic Nt and bind to the ________ receptor(s).

Back 4

alpha and beta adrenergic receptors

Front 5

Exceptions to SNS NT/receptors:

Back 5

1.) in the eccrine type sweat glands, the postganglionic NT is Ach and it binds to the muscarinic receptors M2 or M3
2.) In the renal blood vessels(smooth muscle), the postganglionic nT is Dopamine (DA) which binds to dopaminergic receptors (D1)

Front 6

in the eccrine type sweat glands, (in the SNS), the postganglionic NT is:

Back 6

Ach

Front 7

Ach, the postganglionic NT in the sweat glands in the SNS, binds to the ______ receptor.

Back 7

muscarinic (M2 or M3)

Front 8

The adrenal gland is part of the _____ nervous system.

Back 8

sympathetic

Front 9

the adrenal gland does not have a _____ neuron.

Back 9

postganglionic

Front 10

The adrenal gland's preganglionic NT is Ach (b/c in SNS) which binds to nicotinic receptor causing:

Back 10

Epi, NE, and DA release from the gland into the blood stream. The Epoi and NE bind to alpha and beta adrenergic receptors while DA binds to D1 receptors. (these enhance the actions of the SNS)

Front 11

In the PNS (parasympathetic nervous system), the primary preganglionic Nt is ______.

Back 11

Ach (cholinergic). It binds to nicotinic receptor.

Front 12

In the PNS, the primary postganglionic NT is :

Back 12

Ach. ** it binds to muscarinic receptors M1,M2,M3

Front 13

cholinergic receptors include:

Back 13

nicotinic and muscarinic

Front 14

The third division of the ANS is the:

Back 14

ENS (enteric nervous system)

Front 15

The ENS is unique to the gut. It is found in the gut's muscle layers. Many NT's control it.

Back 15

The ENS is innervated by the SNS and PNS but is not solely controlled by them.

Front 16

the only transmitter in the nmj is___.

Back 16

Ach

Front 17

Ach in the nmj binds to ____receptors.

Back 17

nicotinic

Front 18

the main NTs for the ANS (SNS & PNS) are:

Back 18

Ach, NE, and Epi

Front 19

cholinergic neurons in the ANS synthesize and release____.

Back 19

Ach

Front 20

cholinergic neurons include:

Back 20

1.)preganglionic efferent neurons of the SNS and PNS
2.)All motor fibers to skeletal muscle (nonautonomic)
3.)Postganglionic neurons of the PNS
4.) Some postganglionic neurons of eccrine type sweat glands in SNS

Front 21

adrenergic neurons in the ANS synthesize and release:

Back 21

NE

Front 22

adrenergic neurons include:

Back 22

postganglionic neurons of the SNS

Front 23

adrenal medulla (SNS) is innervated by sympathetic ________ fibers and releases _____________.

Back 23

preganglionic, NE, Epi, & DA

Front 24

in the somatic nervous system (muscle fibers)Ach binds to _____ receptors.

Back 24

nicotinic

Front 25

some tissues receive only PARASYMPATHETIC innervation:

Back 25

nasopharangeal glands

Front 26

some tissues receive only SYMPATHETIC innervation:

Back 26

1.)sweat glands (eccrine and apocrine)
2.) adrenal medulla (adrenal glands)
3.) spleen
4.) SMOOTH muscle (MOST blood vessels)
5.) piloerectors

Front 27

which type of nerve would synthesize and release NE as its neurotransmitter?

Back 27

postganglionic sympathetic

Front 28

a neuron releases Ach from a postganglionic neuron that innervates the eccrine sweat gland is called a _____ _____ neuron.

Back 28

sympathetic, cholinergic

Front 29

on which receptor does the NT released from a postganglionic nerve that innervates apocrine sweat glands act?

Back 29

NE would be released so the receptor would be alpha and beta adrenergic receptors
