Chapter 11 After First Test

Question 0

pathway neuron that goes from CNS to ganglion

Answer 0

preganglionic

Question 1

two neurons in an autonomic pathway

Answer 1

preganglionic and postganglionic

Question 2

pathway neuron that goes from ganglion to target cell

Answer 2

postganglionic

Question 3

blank division of autonomic nervous system is more systemic because it diverges more proximally than distally like blank

Answer 3

sympathetic, parasympathetic

Question 4

ganglia also contain blank which receive input from blank neurons

Answer 4

interneurons, sensory

Question 5

parasympathetic has more rapid local feed back because

Answer 5

more localized than sympathetic

Question 6

some systems are only under blank control by the blank division

Answer 6

tonic, sympathetic

Question 7

examples of only sympathetic tonic control

Answer 7

adrenal medulla, veins/arterioles

Question 8

parasympathetic only uses blank but sympathetic use blank and blank as neurotransmitters

Answer 8

ach, ach, norepinephrine

Question 9

difference between sympathetic and parasympathetic

Answer 9

norepinephrine goes to target cell via a adrenergic receptor whereas parasympathetic has ach that goes to target cell via a muscarinic receptor

Question 10

ach binds to blank receptor in both sympathetic and parasympathetic in the ganglion

Answer 10

nicotinic

Question 11

adding a nicotinic agonist would blank

Answer 11

speed everything up

Question 12

adding muscarinic antagonist would

Answer 12

block parasympathetic pathways would reduce digestive function

Question 13

adding nicotinic antagonist and adrenergic agonist

Answer 13

target cell would still be stimulated because of adrenergic agonist but parasympathetic would be blocked because nicotinic antagonist would block first receptor

Question 14

autonomic neuroeffector junctions differ from a model synapse because there are blank, not discrete axon terminals

Answer 14

varicosities

Question 15

receptors are spread throughout blank instead of blank like in other junctions

Answer 15

membrane, clustered

Question 16

autonomic junctions are a blank specific response and target a blank area

Answer 16

less, great

Question 17

which would have a faster effect on a patient and why?
A. MAO inhibitor
B. Ache inhibitor

Answer 17

Ache because it is in the synapse whereas MAO is in the synaptic cleft so the ligand would have to be pumped back into the cleft before it can be inhibited

Question 18

true endocrine gland of adrenal gland

Answer 18

adrenal cortex (epithelial tissue)

Question 19

modified ganglion part of adrenal gland that is neural tissue

Answer 19

adrenal medulla

Question 20

which of the following describes a chromaffin cell?

Answer 20

Nicotinic receptors because it responds to ach because it is creating adrenaline not responding to it

Question 21

epinephrine is a blank so it is faster in the blood stream because it is smaller than a blank

Answer 21

amine, peptide

Question 22

postganglionic parasympathetics secrete blank onto blank receptors

Answer 22

Ach, muscarinic

Question 23

all postganglionics are blank receptors and there are blank types

Answer 23

g protein coupled, five

Question 24

postganglionics either blank or blank these channels

Answer 24

open, close, K+, Na+

Question 25

blank drugs combine with the receptor

Answer 25

direct

Question 26

blank drugs alter ligand availability or transduction

Answer 26

indirect

Question 27

ibuprofen is a blank because it inhibits the enzyme that creates blank

Answer 27

indirect antagonist, prostaglandins

Question 28

nicotinic receptors are always blank and allow in blank since it is ion gated

Answer 28

excitatory, sodium ions

Question 29

blank pathway has the most sustained response because it is blank

Answer 29

adrenal sympathetic, endocrine

Question 30

blank pathway uses nicotinic like in skeletal muscle so it is always blank

Answer 30

somatic motor, excitatory

Question 31

blank cells do not allow neurotransmitters to diffuse away in somatic motor pathway

Answer 31

Schwann

Question 32

this inhibits nicotinic receptors in skeletal muscle but not in cardiac muscle so there must be blank

Answer 32

curare, isoforms

Question 33

neuromuscular junction nicotinic receptor has blank ion channels and has blank sites that must be filled

Answer 33

chemically gated, two

Question 34

neuromuscular junction nicotinic receptors allow the passage of blank cations that blank the sarcolemma

Answer 34

monovalent (Na+ & K+), depolarizes
