Flashcards in PNS Deck (39):
1
What are the 2 major divisions of the Peripheral NS?
Somatic motor system
Autonomic motor system
2
Which system involves motor movement?
Somatic
3
Which system is self-ruling, meaning we don't have to think about it for it to still work?
Autonomic motor
4
What are the 2 parts to the autonomic motor system?
Parasympathetic
Sympathetic
5
Which part of the autonomic motor system is the rest and digest/peace?
Parasympathetic
6
What are the 7 characteristics of the parasympathetic nervous system?
Decreased HR
Increased Gastric secreation
Emptying bladder
Emptying bowel
Near vision
Pupil constriction
Bronchoconstriction
7
What is the sympathetic system known for?
Fight or flight and stress responses
8
What are the 5 characteristics of the flight or fight response?
-Increased HR and BP
-Shunting blood to skeletal muscles
-Bronchodilation
-Pupil dilation
-Increased glucose (brain) and fatty acids (muscles)
9
What are the 3 cholinergic receptors of the PNS?
Nicotinic(n)
Nicotinic(m)
Muscarinic
10
If a given drug activates nicotinic(n), what 2 things happen in patient response?
Stimulation of sympathetic and parasympathetic postganglionic nerves
Release of adrenalin from adrenal medulla
11
If a given drug activates nicotinic(m), what will happen in patient response?
Contraction of skeletal muscle
12
If a given drug activates muscarinic, what will the patient response be in the EYES?
Contraction of the ciliary muscle/focuses lens on near vision
Contraction of iris sphincter muscle/causes mitosis (decreased pupil diameter)
13
If a given drug activates muscarinic, what will the patient response be in the HEART?
Decreased rate
14
If a given drug activates muscarinic, what will the patient response be in the LUNGS?
Constriction of bronchi
Promotion of secretions
15
If a given drug activates muscarinic, what will the patient response be in the BLADDER?
-Contraction of detrusor (increased bladder pressure)
-Relaxation of trigone spinchter (allow urine to leave the bladder)
-Coordination contraction of detrusor and relaxation of trigon sphincter causing voiding of the bladder
16
If a given drug activates muscarinic, what will the patient response be in the GI?
-Salivation
-Increased gastric secretions
-Increased intestinal tone and motility
17
If a given drug activates muscarinic, what will the patient response be in the SWEAT GLAND?
Generalized sweating
18
If a given drug activates muscarinic, what will the patient response be in the SEX ORGANS?
Erection
19
If a given drug activates muscarinic, what will the patient response be in the BLOOD VESSELS?
VASODILATION
20
What are the 5 adrenergic receptors?
Alpha1, alpha2, beta1, beta2, dopamine
21
If a given drug activates alpha1, what will the patient response be in the EYE?
Contraction of the radial muscle of the iris causing mydriasis (increase in pupil size)
22
If a given drug activates alpha1, what will the patient response be in the ARTERIOLES OF SKIN, VISCERA, MUCOUS MEMBRANES?
Constriction
23
If a given drug activates alpha1, what will the patient response be in the VEINS?
Constriction
24
If a given drug activates alpha1, what will the patient response be in the SEX ORGANS (male)?
Ejaculation
25
If a given drug activates alpha1, what will the patient response be in the PROSTATIC CAPSULE?
Contraction
26
If a given drug activates alpha1, what will the patient response be in the BLADDER?
Contraction of trigone sphincter
27
If a given drug activates alpha2, what will the patient response be in the PRESYNAPTIC NERVE TERMINALS?
Inhibition of transmitter release
28
If a given drug activates beta1, what will the patient response be in the HEART?
-Increased rate
-Increased force of contraction
-Increase AV conduction velocity
29
If a given drug activates beta1, what will the patient response be in the KIDNEY?
Release of renin
30
If a given drug activates beta2, what will the patient response be in the ARTERIOLES OF THE HEART, LUNG, and SKELETAL MUSCLE?
