Q

___ innervates cardiac and smooth muscle, and glands

A

Autonomic Nervous System

22
Q

___ innervates skeletal muscle

A

Somatic Nervous System

23
Q

___ Consists of the axons of motor neurons

A

Somatic Nervous System

24
Q

___ exerts either an excitatory or inhibitory effect

A

Autonomic Nervous System

25
Q

___ Dually innervates itts effector organs

A

Autonomic Nervous System

26
Q

___ Exerts only excitatory effect on its effector organs

A

Somatic Nervous System

27
Q

How does the CNS control muscles and glands?

A

by transmitting signals to effector organs through the efferent division of the peripheral nervous system

28
Q

What are the two types of efferent output?

A

the autonomic nervous system and somatic nervous system

29
Q

Which nervous system is under involuntary control?

A

Autonomic Nervous System

30
Q

Which nervous system is under voluntary control?

A

Somatic Nervous System

31
Q

Where does the autonomic nervous system supply neurons?

A

smooth and cardiac muscle
most exocrine glands
some endocrine glands

32
Q

Where does the somatic nervous system supply neurons?

A

skeletal muscle

33
Q

What are the two subdivisions of the autonomic nervous system?

A

sympathetic nervous system
parasympathetic nervous system

34
Q

An autonomic nerve pathway consists of a __ chain

A

two neuron

35
Q

Autonomic Nerve Pathway: The preganglionic fiber originates in the ___ and synapses with ___ in a ganglion ___ the CNS

A

CNS
the cell body of the postganglionic fiber
outside

36
Q

Autonomic Nerve Pathway: What happens to the postganglionic fiber?

A

it terminates on the effector organ

37
Q

Do neurotransmitters elicit the same response from all tissues?

A

No; response depends on specialization of tissueu cells, not the messenger

38
Q

How does an autonomic fiber effect the organ it innervates?

A

it either excites or inhibits activity

39
Q

Most visceral organs are innervated by…

A

both sympathetic and [arasympathetic nerve fibers

40
Q

How does dual innervation effect visceral organs?

A

sympathetic and parasympathetic nerve fibers generally produce opposite effects in the same organ

41
Q

Why is dual innervation of visceral organs important?

A

it permits precise control over an organ’s activity

42
Q

When does the sympathetic nervous system dominate?

A

in emergency or stressful situations

43
Q

Why does the sympathetic nervous system dominate in in emergency or stressful situations?

A

promotes responses that prepare the body for strenuous physical activity.

44
Q

When does the parasympathetic nervous system dominate?

A

quiet, relaxes situations

45
Q

Why does the parasympathetic nervous system dominate in quiet, relaxes situations?

A

promotes body maintenance such as digestion

46
Q

What are the two types of AChR that bind acetylcholine and transmit its signal?

A

Muscarinic and Nicotinic

47
Q

What do muscarinic and nicotinic receptors due?

A

they are acetylcholine receptors that bind acetylcholine and transmit its signal

48
Q

What type of receptor are muscarinic receptors?

A

G-protein coupled receptors

49
Q

How do muscarinic receptors work?

A

they mediate a slow metabolic response via second messanger cascads

50
Q

What type of receptor are nicotinic receptors?

A

Ligand-gated ion channels

51
Q

All preganglionic fibers and parasympathetic postganglionic fibers release

A

ACh

52
Q

Sympathetic postganglionic fibers release

A

NE
