Muscularsystem

Front 1

Factorsthat lead to increased oxygen consumption

Back 1

1. Increased heat production

2. Increased muscle activity

3. Increased conversion of lactic acid to glucose4. Increased aerobic respiration by muscle cells

Front 2

Fastfibers

Back 2

Have low resistance to fatigue

Have twitches with a very brief contraction phase

Front 3

FastMuscles

Back 3

Adaptto aerobic metabolism by generating more mitochondria in response to repeated,exhaustive stimulation

Front 4

Functionsof a skeletal muscle

Back 4

1. Maintain posture

2. Maintain body temperature

3. Produce movement

4. Guard body entrances and exits

Front 5

HBand

Back 5

Areain the center of the A Band that has NO thin filaments

Front 6

HamstringGroup

Back 6

BF= BicepsFemoris

S2= Semitendinosus

Semimembranosus

Front 7

HumanMuscles

Back 7

1. Have bothslow and fast fibers

2. Eyemuscles are composed entirely of fast fibers

3. Slowmuscles are abundant in thigh muscles

4. Slow fibers are abundant in calf musclese

Front 8

IBand

Back 8

Alwayscontains thin filaments

Front 9

IncompleteTetanus

Back 9

Amuscle producing tension that peaks and falls at intermediate stimulus rates

Front 10

Intercostal

Back 10

Damagewould interfere with breathing

Front 11

IsometricContraction

Back 11

Typeof contraction where the muscle fibers DO NOT shorten

Front 12

IsotonicContraction

Back 12

Muscletension exceeds the load and the muscle lifts the load

Front 13

Latentperiod and Contraction Phase of muscle contraction

Back 13

Calciumions are binding to troponin

Front 14

Lever

Back 14

Consists of:

1. A ridged structure

2. Apivot point or fulcrum

Front 15

MLine

Back 15

Wherethick filaments are linked laterally in a sarcomere

Front 16

MasseterMuscle

Back 16

Thestrongest jaw muscle
