One of the three types of muscles. Muscles move voluntarily and are attached by tendons to bones. They are long, multinucleate (have multiple nucleus), appear striated (due to arrangement of actin and myacin), and are surrounded and bundled by connective tissue. (which supplies nutrients)

A connective tissue wrapping which wraps itself around a single muscle cell/fiber.

A connective tissue wrapping which wraps itself around a fascicle (bundle) of cells/fibers.

A connective tissue wrapping which covers the entire skeletal muscle.

Is a cord like structure which connects muscles to bones. It is formed by epimysium blending into connective tissue attachments.

One of the three different types of muscle tissue. This muscle has no striations and is formed from spindle shaped cells, they possess a single nucleus, move involuntarily, and are found mainly in the walls of hollow organs.

One of the three types of muscle tissues. These have striations, usually a single nucleus, are joined together by another muscle cell by an intercalated disc, function involuntarily, and are found only in the heart.

The cell plasma membrane of a striated muscle cell.

The contractile unit of a myofibril consisting of Z-discs, A-bands, and I-bands.

Movement in the saggital plane that decreases the angle of the joint and brings two bones closer together.

Opposite of flexion; movement in the saggital plane that increases the angle of the joint or distance between two bones or parts of the body.

Movement of a bone around its longitudinal axis.

moving a limb away in the frontal plane from the median plane of the body, spreading the fingers apart

Opposite of abduction; movement of a limb toward the body midline

A combination of all the movements, commonly seen in ball and socket joints where the proximal end of the limb is stationary while the distal end moves in a circle

Thin myofilaments that are anchored to the Z disc

Thick myofilaments that include small projections (heads)

the gap between the axon terminal of a motor neuron and the sarcolemma of a skeletal muscle cell.

the region where a motor neuron comes into close contact with a skeletal muscle cell.

a motor neuron and all the muscle cells it supplies

released by stimulation of a nerve impulse by the axon terminals of the motor neuron

produce contractions in which movement does not occur (same measurement)

covers angle of lower jaw; closes the jaw

covers the front of the neck; pulls down the corners of the mouth (sad clown face)

connect neck to sternum and clavicle; bend head forward (prayer muscle) and rotates head.

covers upper part of chest; adducts the upper arm

straplike muscles of the abdomen; flexes vertebral column

lateral walls of abdomen; flexes and rotates vertebral column

covers the back of the neck and the back of the upper trunk; raises, retracts and rotates the scapula

flat muscles that cover the lower back; extends and adducts humerus (upper arm).

3 deep muscle columns that span the vertebral column; extends and laterally flexes the spine

triangle shaped muscles of the shoulder; abducts arm

muscle in upper arm that bulges when flexed; moves forearm towards the body

located on posterior humerus; extends arm - antagonist of biceps brachii

muscle of the buttock; extends hip when power is needed.

biceps femoris, semimembranosus, and semitendinosus; located on posterior thigh; extend thigh and flex knee

rectus femoris and vastus muscles; located on anterior thigh; extends knee powerfully as when kicking a football

forms calf of posterior leg; prime mover for plantar flexion of foot (toe dancer's muscle)
