25
Q

A fusiform swellings on the posterior root of each spinal nerve just proximal to the root’s junction with a corresponding anterior root?

A

Sensory ganglia

26
Q

Irregular shaped swelling found in the paravertebral sympathetic chains, around the roots of the great visceral arteries in tge abdomen, and close to or embedded to the walls of various viscera

A

Autonomic ganglia

27
Q

Dermatome for umbilical cord

A

T10

28
Q

Dermatome for nipple area?

A

T4

29
Q

How many pairs of spinal nerves and their ganglia?

A

31 pairs

30
Q

What is the parasympathetic nucleus of the occulomotor nerve?

A

Edinger-westphal nucleus

31
Q

Location of the cell bodies of the preganglionic neuron in the ANS?

A

Lateral gray column of the spinal cord

32
Q

It’s function is to prepare the body for emergencies.

A

Sympathetic

33
Q

Effect of synpathetic?

A

Arterioles of the skeletal muscles are dilated

34
Q

Effect of parasympathetic?

A

Heart rate decreased

35
Q

Neurotransmitter used by PREganglionic fibers for sympathetic neurons in the lateral gray columns of the spinal cord?

A

Acetylcholine

36
Q

The myelinated axons of these cells leave the cord in the anterior nerve roots and pass via this area to the paraventebral ganglia of tge sympathetic trunk?

A

White rami communicantes

37
Q

This postganglionic, NONMYELINATED acons leave the paravertebral ganglion and pass to the thoracic spinal nerves as what?

A

Gray rami communicantes

38
Q

These medullary cells, which may be regarded as modified sympathetic Excitor nEurons, are responsible for the secretion of these neurotransmitter.

A

Epinephrine. (3 E)

39
Q

The sympathetic trunks are two ganglionated nerve trunks that extend the whole lenght of the vertebral column. Below, the two trunks terminate by joining together by a single ganglion.

A

Ganglion impar

40
Q

A myelinated efferent fibers of tge craniosacral outflow are preganglionic, and synapse in peripheral ganglia located close to the viscera they innervate. The neurotransmitter is?

A

Acetylcholine

41
Q

Cranial nerves that is part of the cranial sacral outflow.

A

Oculomotor

42
Q

Cranial nerve that is part of parasympathetic nervous system?

A

Faciao

43
Q

CN that is part of parasympathetic nervous system

A

Facial

44
Q

CN part of PNS?

A

Vagus

45
Q

These cells is found in tge autonomic ganglia exhibit catecholamine flourescence. In some ganglia, these interneuorons receive preganglionic cholinergic fibers, and may modulate ganglionic transmission. In other ganglia, they receive collateral branches and may serve some integrative function. And, many SIF cells contain this. What transmitter is this?

A

Dopamine

46
Q

Synaptic transmitter that excites the post ganglionic neurons in both sympathetic and parasympathetic.

A

Acetylcholine

47
Q

It is a nicotinic and muscarinic receptors bind to this neurotransmitter.

A

Acetylcholine

48
Q

Parasympathetic pistganglionic nerve endings liberate this tyoe of neurotransmitter as tgeir transmitter substance.

A

Acetylcholine.

49
Q

Parasympathetic pistganglionic nerve endings are called as what as their substance being utilized?

A

Cholinergic

50
Q

Most sympathetic ganglion nerve endings liberate what as their transmitter substance?

A

Norepinephrine

51
Q

Phenyleohrine is a pure simulator of these receptors?

A

Alpha receptor

52
Q

Norepinephrine has greater effect of what type of receptor?

A

Alpha receptors

53
Q

Bronchodilator drug albuterol mainly acts on what receptor?

A

Beta 2 receptors

54
Q

These receptors are found in the lungs

A

Beta 2 receptors

55
Q

Myelination is caused by

A

Schwann cells

56
Q

Are glial cells that form the myelin sheath on axons outside the brain?

A

Schwann cells

57
Q

specialized regions in the axonal membrane that are not insulated by myelin.

A

Nodes of ranvier

58
Q

Glial cells that forms PNS

A

Schwann cells.
