Muscle tissue that is attached to the bones. This muscle is striated and under voluntary control.
Involuntary muscle tissue found only in the heart.
Muscle tissue in the walls of body organs such as the stomach and intestines. It controls involuntary movement and makes the organs expand and contract.
Contractile unit of muscle
Connects muscle to bone
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.
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.
To waste away
A bundle of muscle fibers
Muscular tissues that surround tubular organs such as the stomach, intestines and blood vessels
Composed of muscular tissue, nervous tissue, blood vessels and connective tissue
Muscular tissue that together forms the heart.
A thick protein filament found in skeletal muscle
A thin protein filament found in skeletal muscle
Message carrying vessels that travel from an axon to the action site of a muscle
The communication port of a skeletal muscle cell that dictates action
A motor neuron and the muscle fibers that it control
A single muscles cell that make up skeletal muscle
A fibril collectively arranged in longitudinal bundles in muscle cells (fibers); composed of thin filaments of actin and a regulatory protein and thick filaments of myosin.
A muscle that is under conscious control
A muscle that is not under conscious control
A muscle that flexes the forearm
A muscle that extends Forearm
Adducts and flexes humerus
The shoulder muscle
Muscle of the back that allows for the adduction of the arms
Elevates, depresses, retracts, and rotates the scapula; rotates the arm
Extends the leg at the knee
Rectus Femoris, Vastus Lateralis, Medias and Intermedias
Allows for flexion of the foot
Rhythmic wavelike contraction of smooth muscles
