Pairs of Muscles that work opposite each other
assist a primary mover
The muscle that acts as the initial and main source of motive power.
Connects muscle to bone
Area of the brain responsible for all voluntary activities of the body
Control of finely coordinated movements. Coordination center, voluntary movement and balance. "Small brain."
State of balanced muscle tension that makes normal posture, coordination, and movement possible
Exercises in which a muscle lengthens and shortens through its full range of movement while lowering and raising a resistance.
Involves muscle contraction w/o shortening (ie, no movement or a min. shortening of muscle fibers). Ex - contracting quadriceps/gluteal muscles.
Muscle contracts isotonically by shortening
A type of isotonic contraction that involves the muscle lengthening while producing tension.
Knowing where our muscles are without looking at them
Adenosine Triphosphate/Chemical energy in cells
Is produced in the muscles when glucose is broken down during strenuous muscular activity. The soreness experience after prolonged heavy exercise is due to accumulated lactic acid in the muscles.
The smooth, sustained contraction of a skeletal muscle
Temporary or permanent loss of motor control
