muscles vocab

a cord of strong, flexible tissue, similar to a rope and connects your muscles to your bones. let's us move our limbs and help prevent muscle injury by absorbing some of the impact your muscles take when you run, jump or do other movements.

• joints

• tendon

• cartilage

• range of motion

the tightening, shortening, or lengthening of muscles when you do some activity.

• contraction

• range of motion

• muscle fatigue

• occupational therapy

a highly organized tissue composed of bundles of muscle fibers called myofibers which contain several myofibrils; voluntary and striated

• cardiac muscle

• smooth muscle

• skeletal muscle

an involuntary, non-striated muscle

• skeletal muscle

• smooth muscle

• cardiac muscle

makes up the thick middle layer of the heart; involuntary and striated

• smooth muscle

• cardiac muscle

• skeletal muscle

the source of energy for use and storage at the cellular level

• adenosine triphosphate (ATP)

• troponin

• myosin

• actin

the functional unit (contractile unit) of a muscle fiber

• sarcomere

• inches

• moles

• centimeters

1. a protein that forms (together with myosin) the contractile filaments of muscle cells, and is also involved in motion in other types of cell.

• troponin

• actin

• myosin

actin-binding proteins that are central to the control of calcium-regulated contraction in striated muscle

• perimysium

• endomysium

• tropomyosin

prototype of a molecular motor—a protein that converts chemical energy in the form of ATP to mechanical energy, thus generating force and movement.

• actin

• myosin

• fascicle
