Q

What is the neuroeffector site?

A

The terminal nerve site for parasympathetic or sympathetic system.

  • where ACH ends for muscarinic parasympathetic system
  • epi and nor epi for sympathetic systems
17
Q

What is another word for cholinergic?

A

Parasympathomimetic

18
Q

What is another word for anti-cholinergic?

A

Parasympatholytic

19
Q

What is another word for adrenergic?

A

Sympathomimetic

20
Q

What is another word for anti-adrenergic?

A

Sympatholytic

21
Q

Effects of Parasympathetic stimulation on heart

SA node and contractility

A
  • SA NODE slowing of rate(decreased HR)

- decreased contractility (decreased atrial force)

22
Q

Effects of Parasympathetic stimulation on lungs

On muscle and on mucous glands

A
  • construction of smooth muscle

- increased mucous secretion

23
Q

What is ACH?

A

Acetylcholine

The chemical used in nerve impulses at all pre ganglionic sites but only in post ganglionic sites of the parasympathetic system

24
Q

Effects of Parasympathetic stimulation on blood vessels

A

Vasoconstriction,

-increased blood pressure due to loss of elasticity

25
Q

Effects of sympathetic stimulation on heart

A

Increased heart rate, increased contractility

26
Q

Effects of sympathetic stimulation on lungs

A

Bronchodilation

Beta 2 effect

27
Q

Effects of sympathetic stimulation on blood vessels

A

Vasodilation

28
Q

What is an M1 innervation do?

A

Increased secretion in nasal passages

29
Q

What is an M3 innervation do?

A

Bronchoconstriction of the airways

30
Q

What is an M2 innervation do?

A

Decreased heart rate and decreased contractility

31
Q

What does antagonist do to M1-M3?

A
  • decrease mucous secretions
  • bronchodilation
  • increased heart rate
32
Q

What can parasympatholytic (anti-muscarinic) agents do?

3 examples

A
  • bronchodilation
  • drying of secretions for preop
  • anti-diarrhea
33
Q

What do alpha sites generally do?

A

EXCITE

-except for intestines and CNS receptors where they relax

34
Q

What do beta sites generally do?

A

RELAX

-except for the heart where it excites it.

35
Q

What do beta 1 receptors do?

A

They excite the heart.
Increase heart rate
Increase contractility

36
Q

What do beta 2 receptors do?

A

The relax bronchiole smooth muscle and vascular beds of skeletal muscle.

37
Q

What do alpha 1 and beta 1 receptors generally do?

A

They excite

38
Q

What do alpha 2 and beta 2 receptors do?

A

INHIBIT
