test 4

Question 1

sympathetic chain ganglia innervate what?

Answer 1

head, body wall, limbs, and viscera of thoracic cavity (heart, lungs)

Question 2

Collateral ganglia are located where?

Answer 2

close to large abdominal arteries

Question 3

name the collateral ganglia divisions

Answer 3

celiac, superior mesenteric, inferior mesenteric ganglia

Question 4

collateral ganglia innervate what and what does activation do?

Answer 4

abdominal and pelvic viscera, decreases blood flow and releases stored energy molecules

Question 5

cranial nerve III controls what?

Answer 5

parasympathetic control of pupil and lens

Question 6

cranial nerve VII controls what?

Answer 6

lacrimal and salivary glands

Question 7

Cranial nerve IX controls what?

Answer 7

salivary glands

Question 8

Cranial nerve X controls what?

Answer 8

• all parasympathetic output

- heart, lungs, digestive tract, all other thoracic and abdominal viscera

Question 9

sympathetic postganglionic axons release what NT on dual effectors?

Answer 9

NE

Question 10

Nicotinic cholinergic receptors are located where and produce what response?

Answer 10

• skeletal muscles, autonomic ganglia

- excitatory

Question 11

Muscarinic cholinergic receptors are located where and produce what response?

Answer 11

• visceral muscles, cardiac muscle, CNS

- excitatory or inhibitory

Question 12

alpha (a1) adrenergic receptors affects what?

Answer 12

smooth muscles of BV of skin and viscera, causes (vaso) constriction= increased BP

Question 13

Beta (B1) adrenergic receptors affects what?

Answer 13

excitatory

• cardiac muscle, kidney adipose tissue
• increase HR and force of contraction

Question 14

Alpha blockers have what effect?

Answer 14

reduce hypertension

Question 15

Beta blockers have what effect?

Answer 15

Beta blockers reduce heart rate

Question 16

Beta (B2) adrenergic receptors affects what?

Answer 16

• inhibitory

- smooth muscles of respiratory tract (bronchioles), BV of heart and skeletal muscle -causes relaxation

Question 17

NE stimulates what more?

Answer 17

Alpha receptors than Beta

Question 18

E stimulates what?

Answer 18

alpha and beta

Question 19

Alpha (A2) have what effects?

Answer 19

inhibitory

-sympathetic inhibitory innervation that directly opposes the parasympathetic system
