Herlihy A&p Chapter 12 - Autonomic Nervous System

Front 1

Automatic body responses are the function of

Back 1

the autonomic nervous system

Front 2

Visceral reflexes regulate ________ function

Back 2

organ

Front 3

The knee-jerk reflex is mediated by ________ nerves

Back 3

somatic

Front 4

Visceral reflexes regulate

Back 4

organ functin such as heart rate, blood pressure, body temp, digestion, airflow , elimination and pupillary responses

Front 5

Lying activates the __________ nervous system

Back 5

sympathetic

Front 6

there are four steps to a visceral reflext

Back 6

1 - activation of a receptor
2 - transmision of sensory information to the CNS
3 - the processing of the information by the CNS
4 - the motor response sent to the effector organ(s)

Front 7

pressure receptors are also known as

Back 7

baroreceptors

Front 8

Pupils when bored

pupils when excited

Back 8

constricted - small

dilate - large, to take it in

Front 9

The Autonomic Nervous System is part of the ______________ that supplies motor activity to the visceral effector organs: glands, smooth muscles within organs and the heart

Back 9

peripheral nervous system

Front 10

Name the two divisions of the ANS

Back 10

sympathetic and parasympathetic

Front 11

What is dual innervation

Back 11

when a single organ receives nerve fibers from both the sympathetic and parasympathetic systems

Front 12

Stimulation of sympathetic fibers increases heart rate

Back 12

stimulation of parasympathetic fibers decrease heart rate

Front 13

In organs with dual innervation, the effects of sympathetic and parasympathetic activity are ____________

Back 13

complimentary. The sympathetic and parasympathetic work in a complimentary way

Front 14

do all organs have dual innervation

Back 14

no - blood vessels are innervated only by the sympathetic nervous system

Front 15

Increased sympathetic activity on blod vessels causes constriction

Back 15

decreased sypatheti activity on blood vessels causes dilation

Front 16

When is the sympathetic nervous system activated

Back 16

during times of stress or threat - "fight or flight"

Front 17

What is autonomic dysreflexia

Back 17

a disordered experienced by a person with a high cervical spinal cord injury. Sympathetic and autonomic systems are not synchronized due to injury

Front 18

When is the parasympathetic nervous system most active

Back 18

it's most active during quiet, nonstressful times. It has a calming effect on the body

Front 19

What role does the parasympathetic nervous system play

Back 19

in the regulation of digetion and in the reproductive function "feed and breed" or "rest and digest"

Front 20

What is paradoxical fear

Back 20

hopeless situations where fight or flight seems futile - can result in uncontrolled urination and defecation, heart rate to decrease

Front 21

dangerously slow heart rate is called

Back 21

bradycardia "bradying down"

Front 22

the effects of adrenal medullary secretion most resembles

Back 22

sympathetic nerve discharge

Front 23

an adrenergic fiber is one that

Back 23

secreate norepinephrine as its transmitter

Front 24

alpha and beta receptors are

Back 24

called adrenergic receptors

Front 25

what is the primary effect of an alpha1 agonist

Back 25

increased heart rate

Front 26

what is most likely to increase the strength of cardic contraction

Back 26

beta1 adrenergic agonist

Front 27

a drug that acts as an anticholinesterase will activate

Back 27

muscarinic receptors

Front 28

what is the basis for the name "belladonna"

Back 28

mydriasis

Front 29

what is related to the "feed and breed" system

Back 29

craniosacral outflow

Front 30

sympathetic and parasympathetic nerves

Back 30

innervate the viscera

Front 31

a drug that causes the heart to beat stronger and faster is called

Back 31

sympathomimetic

Front 32

what is an effect of a postganglionic parasympathetic discharge

Back 32

slowed heart rate

Front 33

vasomotor tone is

Back 33

caused by background firing of the sympathetic nerves supplying the blood vessels

Front 34

paravertebral ganglia

Back 34

are part of the thoracolumbar outflow

Front 35

a beta1 adrenergic agonist

Back 35

increases heart rate

Front 36

atropine is classified as a muscarinic antagonist or blocker and there is

Back 36

vagolytic

Front 37

the vagus nerve is

Back 37

cholinergic, it's transmitter is ACh, and it's effect on the heart is eliminated by a muscarinic blocker

Front 38

Vagal discharge activates

Back 38

muscarinic receptors

Front 39

Which drug classification lowers blood pressure

Back 39

sympatholytic

Front 40

a patient has vagally induced bradycardia. What will relieve bradycardia

Back 40

muscarinic antagonist

Front 41

what is descriptive of dual innervation of the autonomic nervous system

Back 41

sympathetic and parasympathetic

Front 42

the autonomic nervous system functions chiefly in the

Back 42

innervation of smooth muscle in the viscera

Front 43

sympathetic responses generally have widespread effects on the body because

Back 43

preganglionic fibers synapse with serveral postganglionic fibers

Front 44

sympathetic nervous system does not have

Back 44

a localized effect

Front 45

norepinephrine is liberated at

Back 45

most sympathetic postganglionic nerve endings
