Refers to the movement resulting from the contraction of smooth muscles

all-or-none response
Motor unit activation based on need.
recruitment
.The energy needed for muscle contraction comes from a compound called
adenosine triphosphate (ATP)
Skeletal muscle contraction requires to essential ingredients:
Glucose and oxygen.
The wide central portion of a muscle that produces movement of the joint

This muscle hape is called fusiform and converges and one or both ends.
Convergent
A muscle fiber arrangement that is circular. (hello.)
Circular
This muscle hape is called fusiform and converges and one or both ends.
Convergent
A muscle fiber arrangement that is circular. (hello.)
Circular
Short muscles arranged with a central tendon, feather like appearance
Pennate
Muscle causing a specific action.
Agonist
Muscle opposing the agonist.
Antagonist
Muscle aiding by causing same movement as the agonist.
Synergist
Muscle acting as joint stabilizer so agonist can exert it's actions.

AKA red muscle, fatigue resistant, react at a slow rate.
Slow twitch
AKA white muscle, largest diameters, appear white.
Fast twitch
AKA pink muscle, inbetween slow and fast twitch.
Intermediate
The opposite of muscular contraction.

Muscle tension remains the same as length of muscle changes.
Isotonic Contraction
Shortening of the muscle. Accelerators, spurt muscles.
Concentric Contraction
