17
Q

What nervous system controls sweat and digestive glands?

A

ANS

18
Q

ANS is divided into what divisions?

A

Sympathetic and Parasympathetic

19
Q

What ANS sub-system STIMULATES digestive organs?

A

Parasympathetic nerves

20
Q

What ANS sub-system STIMULATES the Heart rate?

A

Sympathetic

21
Q

What glands only receive sympathetic nerves?

A

Sweat glands, many blood vessels, hair muscles

22
Q

Autonomic motor pathway includes what two motor neurons?

A

Preganglionic and post ganglionic neurons

23
Q

What neuron comes from the CNS to the neuron in the autonomic ganglion?

A

Preganglionic

24
Q

What neuron comes from the cell body in the ganglion to the effector?

A

Postganglionic

25
Q

Sympathetic preganglionic neurons are found where?

A

T1-T12 & L1-L2 (thoracolumbar division)

26
Q

One sympathetic ganglion can synapse with how many postganglionic neuron cell bodies?

A

20 or more

27
Q

Sympathetic preganglionic neurons release what neurotransmitter?

A

Epinephrine or norepinephrine

28
Q

Sympathetic postganglionic neurons from the cervical sympathetic trunk serve where?

A

The head (sweat glands, smooth muscles of eyes, blood vessels of face, nasal mucosa, salivary glands)

Some serve the heart

29
Q

Cell bodies located in the “Prevertebral ganglia” follow which 3 large abdominal arteries and supply the viscera, are called?

A

Celiac, Superior and Inferior Mesenteric ganglia

30
Q

Parasympathetic preganglionic neurons are located where?

A
  1. Brainstem (nuclei of CN III, VII, IX, X)

2. S2-S4

31
Q

Carries 80% of parasympathetic nerve impulses

A

CN X: Vagus

32
Q

Vagus nerves carries what type of neurons to/from the viscera?

A

Motor AND Sensory

33
Q

Where are parasympathetic postganglionic neurons located?

A

In the terminal ganglia which are located within or near the innervated organ.

Cause precise, localized effects (not widespread).

34
Q

Unlike Sympathetic nerves, parasympathetic nerves do not reach some tissue like:

A

Sweat glands, hair muscles, kidneys, spleen, adrenal medullae, and walls of most blood vessels

35
Q

SLUDD

Salivation
Lacrimation
Urination
Digestion
Defecation
A

Parasympathetic

36
Q

Which ANS division mobilizes nutrients for energy (glucose & fats)?

A

Sympathetic

37
Q

Upper motor neurons are part of what nervous system?

A

CNS

38
Q

Lower motor neurons are part of what nervous system?

A

PNS

39
Q

Most viscera are supplied with both sympathetic and parasympathetic nerves, this is called:

A

Dual innervation
