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
