A

condition in susceptible individuals resulting in a life-threatening elevation in body temperature

19
Q

myofilaments

A

minute fibers located throughout the cytoplasm of cells, composed of the protein actin, that maintain the structural integrity of a cell

20
Q

mitochondria

A

normal structures responsible for energy production in cells

21
Q

myelin

A

the fatty substance that covers and protects nerves and allows efficient conduction of action potentials down the axon

22
Q

neuromuscular junction (NMJ)

A

area where the motor neuron axon terminal meets the muscle tissue

23
Q

neurotoxin

A

a substance that is destructive to nerve tissue

24
Q

nicotinic-muscle (Nm) receptor

A

cholinergic receptor located at the neuromuscular junction of skeletal muscle

25
Q

nondepoloraizing blocker

A

produces paralysis by inhibiting nerve transmission

26
Q

peripheral skeletal muscle relaxant

A

drug that inhibits muscle contraction at the neuromusular junction or within the contractile process

27
Q

potentiates

A

produces an action that is greater than either of the components can produce alone; synergy

28
Q

sarcolemma

A

a thin membrane enclosing a striated (skeletal) muscle fiber

29
Q

sarcoplasm

A

the cytoplasm of a striated(skeletal) muscle fiber

30
Q

sarcoplasmic reticulum

A

specialized organelle in the muscle cell that released calcium ions during muscle contraction and absorbs calcium ions during relaxation

31
Q

schwann cell

A

any cell that covers the axons in the peripheral nervous system and forms the myelin sheath

32
Q

spasmolytics

A

drugs that relieve, interrupt, or prevent muscle spasm (intermittent muscle contractions often associated with pain)

33
Q

spread effect

A

condition in which the intramuscularly injected substance moves out of the area of administration and produces an effect on other tissues

34
Q

strabismus

A

conditon in which the eyes are not aligned and point in different directions (cross- eyed)

35
Q

synaptic cleft

A

space (synapse)between a motor nerve ending and a skeletal muscle membrane that contains acetylcholine (ACH) receptors

36
Q

synaptic knob

A

contains vesicles that store and release neurotransmitters

37
Q

synaptic vesicles

A

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
Q

vagolytic action

A

inhibition of the vagus nerve to the heart causing the heart rate to increase (counteraction to vagal tone that causes bradycardia)

39
Q

vasodilator

A

substance that relaxes the muscle (schincters)controlling blood vessels, leading to increased blood flow
