is the amount of response your muscles give to stimuli

means that if muscles are stretched, they recoil to their original resting length.

# data[].attributes.body
means that muscles can be stretched to their normal resting length and beyond to a limited degree

# data[].attributes.body
refers to the capacity of muscle to contract or shorten forcefully. Excitability means that muscle responds to stimulation by nerves and hormones, making it possible for the nervous system and, in some muscle types, the endocrine system, to regulate muscle activity.

When the brain signals the muscle to contract, the body pulls calcium from the blood into the muscle cells. The calcium binds with the troponin and draws it out of position. ... When the troponin and tropomyosin move, this activates the actin and myosin to move toward each other and contract the muscle

# data[].attributes.body
is a motor protein that also helps muscle contractions, it moves against the actin cells which creates the atp energy for movement

# data[].attributes.body
is important for muscle cells to develop muscle, also helps muscles contract

According to the sliding filament theory, the myosin (thick) filaments of muscle fibers slide past the actin (thin)filaments during muscle contraction, while the two groups of filaments remain at relatively constant length.

is a disorder caused by a deficiency in calcium, which causes intermittent muscular spasms

# data[].attributes.body
(also called lockjaw)A serious bacterial infection that causes painful muscle spasms and can lead to death.

examples of this is like the gluteus maximus, are slow twitch dominant

# data[].attributes.body
spasms refer to alternating involuntary muscular contraction and relaxation in quick succession

# data[].attributes.body
is the involuntary contraction or tensing of the muscles in any area of the body, is usually a short lived abrupt pain

# data[].attributes.body
is the decline in ability of a muscle to generate force. It can be a result of vigorous exercise but abnormal fatigue may be caused by barriers to or interference with the different stages of muscle contraction.

-makes movement possible
-move food through the digestive tract
-movement aids bloodflow
-movement aids fluids to move through ducts and tubes associated with other body system
