Muscular System

Front 1

types of muscle tissue

Back 1

-skeletal
-smooth
-cardiac

Front 2

functions of muscle tissue

Back 2

-motion
-stabalizing body and regulating organ volume
-heat production/thermogensis
-movement of substances in the body

Front 3

excitability

Back 3

ability to respond to certain stimuli by producing electical signals called nerve impulses

Front 4

contractility

Back 4

ability of the muscle to shorten and thicken

Front 5

extensibility

Back 5

ability of the muscle to stetch or extend with out damage

Front 6

elasticity

Back 6

ability of the muscle tissue to return to original state or shape

Front 7

conductivity

Back 7

ability of muscle or nerve cells to conduct or pass through an impulse

Front 8

loose conective tissue (hypodermis) functions

Back 8

-stores water and fat
-insulation
-mechanical protection
-pathway for nerves

Front 9

deep connective tissue (deep fascia) functions

Back 9

-holds muscle together
-allows free movement of muscle
-carries neerves and blood Vessels
-fills in space between muscles
-surrounds organs

Front 10

types of deep CT

Back 10

-epimysium
-perimysium
-endomysium
-tendon
-aponeurosis
-tendon sheath

Front 11

motor unit

Back 11

a motor neuron, axon, axon branches, and all skeletal muscle fibers

Front 12

neuromuscular junction

Back 12

the region where the nerve and muscle communicate

Front 13

sarcomere

Back 13

the functional unit of the muscle cell

Front 14

muscle contraction specifics

Back 14

nerve impulse-axon-axon terminal-synaptic end bulb-synaptic cleft (gap)-motor end plate-T tubules-the release of calcuim to bind with troponin to contract muscle

Front 15

synaptic end bulb

Back 15

hold acetylcholine and relaeses it when the impulse tells it to

Front 16

motor end plate

Back 16

part of muscle that has receptors that pick up acetylcholine that opens sodium channels allowing sodium to rush in making the cell more positive

Front 17

T Tubules

Back 17

tells the sacroplasmic reticulum to release calcium

Front 18

hypotonia
hypertonia

Back 18

-decrease or lost muscle tone
-increase in muscle tone

Front 19

flaccid

Back 19

loose, flabby, no muscle tone

Front 20

spasticity

Back 20

hypertonia with increase muscle tone (cramp)

Front 21

hypertrophy

Back 21

excessive enlargement

Front 22

anaerobic process
aerobic process

Back 22

-without oxygen and not producing enough ATP
-with oxygen and working out

Front 23

myalgia

Back 23

muscle pain

Front 24

isotonic contractions
isometric contractions

Back 24

-muscle shortens, tension stays the same
-when tension on a muscle increases but muscle length stays the same

Front 25

agonist
antagonist
fixator
synergist

Back 25

-primary mover (bicep)
-opposing muscle that relaxes (tricep)
-stabalizes and holds the proximal joint (deltoid)
-what assists the agonist (brachial radialus)

Front 26

skeletal muscle tissue

Back 26

-attaches to bone, Striated and Voluntary

Front 27

smooth muscle tissue

Back 27

locates in organs and vessels, non-striated and involuntary

Front 28

cariac muscle tissue

Back 28

forms most of the heart, striated, and involuntary

Front 29

epimysium

Back 29

-outermost layer that



muscle, and attaches to bone,

Front 30

perimysium

Back 30

intermediate layer that surrounds fasicles of muscle fiber

Front 31

endomyseium

Back 31

innner most layer that surrounds each individual muscle fiber

Front 32

tendon

Back 32

attaches muscle to bone, dense CT

Front 33

apneurosis

Back 33

sheet-like tendon, extension of muscle and attaches bone, skin, and muscle t

Front 34

tendon sheath

Back 34

contains a film of synovial fluid to reduce friction
