Connective Tissues and Fascicles

Synergist

A muscle that aids the prime mover

Triangular Muscles

Fan shaped broad at one end.

Pennate

Feathered-shaped

Epimysium

Fibrous sheath that surrounds the entire muscle

Circular Muscles

Form rings around certain body openings.

Muscle Compartment

Group of functionally related muscles enclosed separated from others by connective tissue fascia

Prime Mover

Is a muscle that produces most of the force during a particular joint action

Indirect Attachement

Muscle ends conspicuously short of its bony destination, and the gap is bridged by a fibrous band of sheet called a tendon

Fixator

Prevents a bone from moving

Aponeurosis

Referred to the tendon located beneath the scalp

Fascia

Sheet of connective tissue that separates neighboring muscles groups from each other.

Orgin

The bony site of attachment at the relatively stationnary end is called the orgin

Action

The effect produced by a muscle, weather it is to produce or prevent a movement is called action

Insertion

The site that is more mobile is called insertion

Fusiform Muscles

Thick in the middle and tapered at each end

Perimysium

Thicker connective tissue sheath that wraps muscle fibers together

Endomysium

This is a thin sleeve of connective tissue that surrounds each muscle fiber. It creates room for blood capillaries and nerve fibers.

Parallel Muscles

Uniform width and parallel fascicles. Some are elongated straps

retinaculum

groups of tendons from separate muscles pass under a band of connective tissue

Direct (fleshy) attachement

little separation between muscle and bone
