Q

nicotinic-muscle (Nm) receptor

Study These Flashcards
A

cholinergic receptor located at the neuromuscular junction of skeletal muscle

25
nondepoloraizing blocker
produces paralysis by inhibiting nerve transmission
26
peripheral skeletal muscle relaxant
drug that inhibits muscle contraction at the neuromusular junction or within the contractile process
27
potentiates
produces an action that is greater than either of the components can produce alone; synergy
28
sarcolemma
a thin membrane enclosing a striated (skeletal) muscle fiber
29
sarcoplasm
the cytoplasm of a striated(skeletal) muscle fiber
30
sarcoplasmic reticulum
specialized organelle in the muscle cell that released calcium ions during muscle contraction and absorbs calcium ions during relaxation
31
schwann cell
any cell that covers the axons in the peripheral nervous system and forms the myelin sheath
32
spasmolytics
drugs that relieve, interrupt, or prevent muscle spasm (intermittent muscle contractions often associated with pain)
33
spread effect
condition in which the intramuscularly injected substance moves out of the area of administration and produces an effect on other tissues
34
strabismus
conditon in which the eyes are not aligned and point in different directions (cross- eyed)
35
synaptic cleft
space (synapse)between a motor nerve ending and a skeletal muscle membrane that contains acetylcholine (ACH) receptors
36
synaptic knob
contains vesicles that store and release neurotransmitters
37
synaptic vesicles
a small membrane-bound structure in the axon terminals of nerve cells that contains neurotransmitters and releases them when an action potential reaches the terminal
38
vagolytic action
inhibition of the vagus nerve to the heart causing the heart rate to increase (counteraction to vagal tone that causes bradycardia)
39
vasodilator
substance that relaxes the muscle (schincters)controlling blood vessels, leading to increased blood flow
40
amide local anesthetic
anesthetic class that includes lidocaine, bupivicaine, and mepivicaine and has a moderate to long duration of action because metabolism occurs in the liver
41
cardiac arrhythmia
variation in the normal rhythm (motion) of the heart
42
caudal anesthesia
injection of a local anesthetic into the caudal or subcaudal spinal canal
43
cryoanesthesia
removing the sensation of touch or pain by applying extreme cold to the nerve endings
44
epidural anesthesia
injection of a local anesthetic into the extradural (the outermost part of the spinal canal) space
45
ester local anesthetic
anesthetic class that includes procaine, cocaine, benzocaine, and tetracaine: metabolism is primarily by plasma cholinesterases
46
general anesthetic
drug that abolishes the response to pain by depressing the central nervous system (CNS) and producing loss of consciousness
47
hypersensitivity
exaggerated response such as a rash, edema,or anaphylaxis that develops following exposure to certain drugs or chemicals
48
infiltration anesthesia
injection of a local anesthetic directly into the tissue
49
intradermal anesthesia
injection of a local anesthetic into the part of the skin called the dermis
50
local anesthetic
drug that reduces response to pain by affecting nerve conduction. the action can be limited to an area of the body according to the site of administration
51
nerve conduction
transfer of impulses along a nerve by the movement of sodium and potassium ions
52
regional nerve block
also called nerve block; the injection of a local anesthetic near the nerve root
53
spinal anesthesia
injection of a local anesthetic into the subarahonoid space
54
topical application
placing a drug on the surface of the skin or mucous membrane ex- mouth / rectum
55
vasoconstriction
tightening or contraction of muscle (schincters) in the blood vessels, which decreases blood flow through the vessels
56
vasodilation
relaxation of the muscles (sphincters) controlling blood vessel tone, which increases blood flow through the vessels
57
Ester =
short
58
Amide=
long (liver)
59
Epinephrine combined with Anesthetic does what?
works longer
