Autonomic Nervous System

Question 1

involuntary nerve cells that transmit impulses to smooth muscles

Answer 1

Autonomic Nervous System ANS

Question 2

“Rest and Digest” 
◦ Constricts pupils
◦ Stimulates salivation 
◦ Lowers heart rate
◦ Constricts breathing 
◦ Stimulates digestion

Answer 2

Parasympathetic Division

Question 3

“Fight or Flight” 
◦ Dilates pupils 
◦ Inhibits salivation 
◦ Increase in heart rate 
◦ Facilitates breathing 
◦ Inhibits digestion

Answer 3

Sympathetic Division

Question 4

How does one neuron communicate with the next neuron and with the organ they innervate?

Answer 4

Via neurotransmitters

Chemical substances made in the neurons that are released when an action potential comes down the neuron

Question 5

Sympthatetic or Parasympathetic come from the

SACRAL NERVES AND CRANIAL NERVES

Answer 5

PARASYMPATHETIC

Question 6

Sympthatetic or Parasympathetic come from the

THORACIC NERVES/CERVICAL/LUMBAR

Answer 6

SYMPATHETIC

Question 7

PARASYMPATHETIC HAS LONG OR SHORT BRANCHES POST AND PRE GANGLION

Answer 7

SHORT PRE GANGLION

LONG POST GANGLION

Question 8

Types of Neurotransmitters

Answer 8

Primary Neurotransmitters

• acetylcholine ACh
• Norepinephrine (NE)

Other Neurotransmitters include:

• Epinephrine (EPI)
• Dopamine
• Serotonin
• GABA (gamma aminobuteric acid)

Question 9

Sympathetic Division what are the prominent receptors

Answer 9

Adrenergic Receptors

Question 10

Parasympathetic Division what are the prominent receptors

Answer 10

Cholinergic receptors

Question 11

Alot of drugs do not effect the ____ receptors.

a. Cholinergic Receptors
b. Adrenergic Receptors

Answer 11

a.

Question 12

Cholinergic Receptors break down into 2 types of receptors

Answer 12

Muscarinic

Nicotinic

Question 13

• Innervates sweat glands, blood vessels and smooth muscle

- Slows cardiac function

Answer 13

Muscarinic

Question 14

Causes skeletal muscle to contract

Answer 14

Nicotinic

Question 15

**Acetylcholine released from the parasympathetic preganglionic and postganglionic nerves

in the PARASYMPATHETIC DIVISION Cholinergic receptors

Answer 15

Neurotransmitter

Question 16

Sympathetic Dvision -> Adrenergic Receptors gets broken down into

Answer 16

alpha and beta

with subdivisions a1, a2, b1, b2

There is also neurotransmitters

Question 17

How do the neurotransmitters work in the synmpathetic division

Answer 17

ACh is released from all PREGANGLIONIC neurons

NE is released from most postganglionic neurons, which then crosses the synapse and has an effect on the tissue/organs, neurepineprine is relases and sometiems epinephrine

Question 18

How do the neurotransmitters work in the parasympathetic division

Answer 18

Acetylcholine released from the parasympathetic preganglionic and postganglionic nerves

Question 19

• located on smooth muscle tissue, produces smooth muscle contractions (blood vessels, sweat glands, eye, intestine)
• Located in bronchi, relaxes uterine and vascular smooth muscle
• Located in cardiac tissue, increase heart rate and contractility
• located on postganglionic neurons, inhibits release of NE, decreases BP, decrease secretion of insulin

Answer 19

1. a1
2. b2
3. b1
4. a2

Question 20

Autonomic Drugs

Agonists
Antagonist

Answer 20

Agonist- Drugs that bind with a receptor to produce an effect

Antagonist- Drugs that bind with a receptor to block results on an agonist to produce results

Question 21

Is a drug which imitates the action of neurotransmitters

Produces an action or response

Answer 21

Agonist

Question 22

Parasympathetic Nervous System Receptors

Answer 22

• Cholinergic Agonists

- Anticholinergic (Cholinergic antagonists)

Question 23

2 subdivisions of Cholinergic Agonists

2 subdivisions of cholinergic antagonists

Answer 23

• Muscarinic
• Nicotinic
• Muscarinic anticholinergic
• Nictotinic anticholonergic(block muscarinic and nicotinic receptors)

Question 24

Sympathetic Nervous Systems consists of what 2 agonist and antagonist

Answer 24

• Adrenergic Agonists (sympathomimetic drugs)

- Adrenergic Antagonist (sympatholytic drugs)

Question 25

• Stimulate receptors in the sympathetic or adrenergic nervous
system

Answer 25

Adrenergic Agonist

Question 26

Directly block the a- and b-adrenergic receptors on tissues,
resulting in a decrease sympathetic activity

Answer 26

Adrenergic Antagonists
