MUSCULAR part 2 Flashcards
Muscle connected to the bone
Tendon
Broad, sheet-like tendons
Aponeuroses
Band of connective tissue that holds down the tendons at each wrist and ankle
Retinaculum
Head; most stationary end of the muscle
Origin
End of the muscle attached to the bone with greatest movement
Insertion
Between the origin and insertion
Belly
Muscle causing specific/certain movement
Agonist
Muscles causing OPPOSITE movement
Antagonist
Muscle working together
Synergist
A muscle that plays the major role in accomplishing desired movement
Prime mover
Muscles that hold one bone in place relatively to the body
Fixators
Arranged in a circle around an opening; act as sphincters
Circular
Broadly distributed fascicles CONVERGE at a single tendon
Convergent
lie PARALLEL TO ONE ANOTHER and to the long axis of muscle
Parallel
A pattern of pennate; fascicles are ONLY at the ONE side of tendon
Unipennate
A pattern of pennate; fascicles are on the BOTH SIDES of the tendon
Bipennate
A pattern of pennate; fascicles ARRANGED IN MANY PLACED around the central tendons
Multipennate
Lie parallel to the long axis of muscle; belly of muscle is larger in diameter than ends
Fusiform
Muscles of head and neck includes:
Facial Expression
Mastication
