Q

Smooth muscle

A

Controlled by Autonomic nerve system, tube/hollow organ

16
Q

Cardiac muscle

A

Found in the heart, modulated by neural activity

17
Q

Skeletal muscle

A

Moves us around and responsible for most our behavior; controlled

18
Q

How is atp used in muscle contraction and where does I come from

A

Creatine phosphate, glycogen, aerobic respiration

19
Q

Isometric vs isotonic

A

Isometric- muscle cannot move load

Isotonic- muscle exerts constant load

20
Q

Concentric

A

Muscle shorten

21
Q

Eccentric

A

Muscle lengthens due to stretching of external force (walking down stairs)

22
Q

Oxidative phosphorylation

A

Purification acid -> Krebs cycle -> CO2 H2O 36 ATP

23
Q

Muscle fatigue

A

Relative deficit of atp , other contributors: lactic acid, ionic imbalance
