Pharmacology Phys. Of Pns Chapt. 13

Front 1

The division of the nervous system that consists of the brain & spinal cord.

Back 1

CNS

Front 2

The division of the nervous system that consists of the somatic & autonomic nervous syst.

Back 2

PNS

Front 3

The part of the PNS that is further sub-divided into the parasympathetic nervous system & the sympathetic nervous system that regulates many involuntary processes. (e.g. 1)reg of heart, 2)reg of secretatory glands,3)reg of smooth muscles.)

Back 3

Autonomic Nervous System

Front 4

The division of the PNS that involves system controls movement of voluntary muscles.

Back 4

Somatic Motor

Front 5

Slowing of HR, Increased gastric content, Emptying bladder & bowel, near vision focusing, contricting pupil & bronchial smooth muscles are all functions of which division of the nervous syst.?

Back 5

PNS

Front 6

The three main functions of this part of the nervous syst. are reg of cardiovascular syst. reg of body temp. Implementation of fight or flight reaction.

Back 6

SNS

Front 7

Poisons act upon this division of the nervous system.

Back 7

PNS

Front 8

Mechanisms of regulation of this part of the nervous system manages patterns of innervation & control, feed back regulation, & autonomic tone.

Back 8

Autonomic NS

Front 9

A process that allows a system to adjust itself by responding to incoming information. It can involve a sensor, an effector, and neurons connecting to either.

Back 9

Feed Back Regulation

Front 10

With regards to feed back regulation the purpose of this is to monitor the status of a physio process. Info picked up by this, is sent to the CNS where it is integrated w/other relevent inf.

Back 10

Sensor

Front 11

Signals from the sensor (i.e. instructions for change) are then sent from the CNS along nerve of the ANS to this. In response, this makes appropriate adjustments in the process. Entire process is termed as a reflex.

Back 11

Effector

Front 12

Located in the carotid sinus & aortic arch, which monitors changes in BP & sends this info to the brain. In response to alterations, the brain sends impulses along nerves of ANS instructing heart & blood vessles to restore BP in an attempt towards normalcy.

Back 12

Baroreceptor Reflex

Front 13

When BP falls, the baroreceptor reflex causes **** along with elevation of CO so as to bring up BP.

Back 13

Vasoconstriction

Front 14

When BP is too high, the baroreceptor reflex causes this effect to happen, whereby causing CO to do reduce causing a drop in BP.

Back 14

Vaso-Dialation

Front 15

Refers to the steady, day-to-day influence exerted by the ANS on a particular organ or organ syst. By having one divsion of the ANS,it providew the basal control to an organ, whereas conflicting signals are avoided.

Back 15

Autonomic Tone

Front 16

The junction "between" two neurons.

Back 16

Synapse

Front 17

Neurons that go from the spinal cord to the parasympathetic ganglia are called this.

Back 17

Preganglionic Neurons

Front 18

Neurons that go from the ganglia to effector organs are called this.

Back 18

Postganglionic neurons

Front 19

The transmitter that's 1)released by all pre & post-ganglionic neurons of the PNS, 2)All pre & post-ganglionic neurons of the SNS (particulary sweat glands) & all motor neurons & skeletal muscles.

Back 19

Ach

Front 20

The transmitter that's released by practically all postganglionic neurons of the SNS (i.e. w/exception to post-ganglionic synanptic neurons going to sweat glands).
(Repeat Question)

Back 20

Nor-epi

Front 21

The major transmitter released by the adrenal medulla, which activates everything.

Back 21

Epinepherine

Front 22

Receptors that are defined as ones that are mediated responses to Ach at all junctions where Ach is the transmitter.

Back 22

Cholinergic

Front 23

Defined as receptors that mediate responses to both epi & norepi.

Back 23

Andrenergic

Front 24

Cholinergic receptor subtype that's loc. on the cell bodies of all post-ganglionic neurons of the PNS & SNS and on cells of the adrenal medulla. Promotes ganglionic transmission at all gangila & promotes release of epinephrine from the adrenal medulla.

Back 24

Nicotinic(n)

Front 25

Cholinergic receptor subtype that are loc. on all organs regulated by the PNS & sweat glands. Causes increased glandular secretions, contraction of smooth muscle in bronchi & GI, slowing of heart, contraction of iris sphincter & cilliary muscles of eye and voiding of urinary bladder.

Back 25

Muscarinic

Front 26

Cholinergic receptor subtype that are loc.on skeletal muscles, which causes contraction of them.

Back 26

Nicotinic(m)

Front 27

Adrenergic receptor subtype that are loc in the eyes, blood vessels, male sex organs, prostatic capsule & bladder(trigone & sphincter).
Activation causes vasconstriction & contraction

Back 27

Alpha 1

Front 28

Alpha 1 receptors that are present on the radial muscle of the iris. Activation causes dialation of the pupil.
(i.e. What Organ)

Back 28

Ocular

Front 29

Alpha 1 activation of receptors in blood vessels produces this effect to happen and are present on veins & on arterioles in many capillary beds.

Back 29

Vaso-Constriction

Front 30

Activation of alpha 1 receptors in the sexual apparatus in males causes this.

Back 30

Ejaculation

Front 31

Alpha 1 activation of receptors in smooth muscle of the bladder(trigone & sphincter) & prostatic capsule causes this effect to happen.

Back 31

Contraction

Front 32

Receptors of the PNS that are loc. on nerve terminals & not on the organs intervated by the ANS. Funct. is to regulated transmitter release; but have little clinical significance.

Back 32

Alpha 2

Front 33

Another Subcatagory of Adrenergic Receptor subtypes loc. in the heart & the kidney. Activation increases HR in the heart & release of Renin in the kidneys.

Back 33

Beta 1 activation through this organ causes release of renin, which prmotes synth. of angiotensin, a powerful vasoconstrictor, where activation is a means by which the NS helps elevate BP.

Back 36

Kidney

Front 37

Beta 2 activation of receptors in the lungs, causes this effect to occur in the bronchiols.

(i.e In general, beta 2 activation causes relasxtion, & vasodilation).

Back 40

Glycogenolysis & Contraction

Front 41

In the periphery of the kindeys only this type of receptor is of clinical significance, and are loc. in the vasculature of the kidney. Activation of these receptors will do this effect to renal blood vessels, thereby enhancing renal perfusion.
