Norepinephrine and acetylcholine have what kind of effects on smooth muscle, cardiac muscle, and glands

25
Q

Pre synaptic sympathetic axons are _ and pre synaptic parasympathetic neurons are _

A

Short, long

26
Q

Post synaptic sympathetic neurons are _ and post synaptic parasympathetic neurons are _

A

Long, short

27
Q

Parasympathetic division of ANS doesn’t have

A

Sweat glands

28
Q

Parasympathetic division of ANS are also called the…

A

Craniosacral division of the ANS

29
Q

In the Parasympathetic division, pre synaptic cell bodies are located in the

A

Brainstem and sacral spinal cord S2-S4

30
Q

The parasympathetic division function

A

Rest and digest; heart rate decreases, bronchioles constrict, and digestion salivation lacrimation increase.

31
Q

The cell bodies of post synaptic neurons located in the ganglia are

A

Close to target structures

32
Q

The cranial nerves that have a parasympathetic component are the

A

Oculomotor, facial, vagus, and glossopharyngeal

33
Q

The presynaptic parasympathetics originate in the

A

Brainstem and sacral spinal cord

34
Q

The cranial nerves distribute parasympathetics to the smooth muscle, cardiac muscle, and glands above the

35
Q

The parasympathetics from S2 and S4 are distributed to the

A

Colon, pelvis, and external genitalia

36
Q

There are no cranial nerves in the

A

Sympathetic

37
Q

The sympathetic division of the ANS is also called the

A

Thoracolumbar division

38
Q

In the sympathetic division, pre synaptic cell bodies are located within

A

The gray matter, lateral horns, of spinal cord between T1-L2

39
Q

In the sympathetic division, Most of the cell bodies of the post synaptic neurons are in the

A

Sympathetic chain/trunk

40
Q

The sympathetic chain includes a string of

41
Q

In the sympathetic division, once synapse occurs…

A

Post synaptic axons can travel up the chain into the head and neck, and down chain into pelvis

42
Q

The sympathetic division function

A

Exercise, physical activity; bronchioles dilate, digestion/salivation/lacrimation decreases, heart rate increases, and sweating increases

43
Q

Parasympathetic component of the oculomotor nerve…

A

Causes Pupils to constrict and thickening of lens

44
Q

The sympathetic function of oculomotor nerve

A

Pupils dilate and lens becomes thinner

45
Q

Cranial nerves also deceiver parasympathetics to the

A

Lacrimal gland and salivary glands

46
Q

Parasympathetic function of facial nerve

A

Lacrimation, mucus production, and salivation

47
Q

Parasympathetic function of glossopharyngeal nerve

A

Salivation

48
Q

Parasympathetic function of the vagus nerve

A

Bronchial construction, increase heart rate and action of digestive system (thorax and abdomen)

49
Q

Spinal nerves go to the

50
Q

The body wall includes the

A

Thoracic wall, abdominal wall, and extremities

51
Q

Extremities are outgrowths of the

52
Q

In the sympathetic division, the sympathetic chain extends into the

A

Down intoPelvis and up into neck

53
Q

Connecting branches connect the

A

Spinal nerve and sympathetic trunk

54
Q

In the post synaptic neuron of the sympathetic chain….it can

A

Rejoin spinal nerves that go to the body wall to sweat glands

55
Q

Sympathetics that go to internal organs use

A

Splanchnic nerves

56
Q

Splanchnic nerves branch from the

A

Sympathetic trunk and enter the body cavities

57
Q

The fight of flight response is how the

A

Sympathetic division of the ANS responds to an emergency situation

58
Q

Fight or flight response occurs in what levels

59
Q

The pre synaptic sympathetic neurons of fight or flight don’t…

A

Meet up with postsynaptic neurons, they meet up with adrenal glands, produce adrenaline, and it circulates in the bloodstream
