The Muscular System word list, defined
- MUSCLE /ˈmʌsəl/ · noun; verb
- A muscle is a tissue in the body that contracts and relaxes to produce movement, maintain posture, or perform an internal function. As a verb, muscle means to exert force or influence in order to achieve something. Related: brawn, strength, power, force.
- TENDON /ˈtɛndən/ · noun
- A tough band of connective tissue that attaches muscle to bone and transmits the force of muscle contraction. Tendons may also connect muscle to muscle or other structures. Related: sinew.
- LIGAMENT /ˈlɪɡəmənt/ · noun
- A tough, flexible band of connective tissue that joins bones or cartilage and helps stabilize parts of the body. By extension, a ligament can be a unifying bond between people, groups, or ideas. Related: bond, tie, band, sinew.
- FIBER /ˈfaɪbər/ · noun
- A thread-like structure of natural or synthetic material, such as the strands forming plant tissue, muscle, cloth, or nerves. More broadly, it denotes dietary material from plants that the body cannot fully digest, and figuratively, essential character or texture. Related: thread, strand, filament, fibril.
- SARCOMERE /ˈsɑː.kə.mɪər/ · noun
- A sarcomere is one of the repeating contractile units that make up the striated muscle fibers of skeletal and cardiac muscle. Each sarcomere contains organized filaments of actin and myosin whose interaction produces contraction. Related: myofibrillar segment, muscle segment, contractile unit.
- MYOSIN /ˈmaɪəsɪn/ · noun
- Myosin is a family of motor proteins that bind to actin and use energy from ATP to generate movement or force. In muscle, myosin forms the thick filaments that interact with actin to produce contraction, while related forms of myosin perform movement in non-muscle cells. Related: motor protein, muscle protein.
- ACTIN /ˈæktɪn/ · noun
- A protein that forms thin filaments in muscle cells and is a major component of the cytoskeleton of all eukaryotic cells, essential for muscle contraction, cell movement, and cell division.
- ATROPHY /ˈætrəfi/ · noun and verb
- (Noun) The gradual wasting away or degeneration of a body part, tissue, or organ, typically through lack of use, disease, or inadequate nourishment. (Verb) To waste away, decline, or deteriorate in this manner. Related: wasting, degeneration, decline, deterioration.
- CONTRACT /ˈkɒntrækt/ (noun); /kənˈtrækt/ (verb) · noun, verb
- As a noun, a contract is a written or spoken agreement between two or more parties that is enforceable by law. As a verb, to contract means to decrease in size or number, or to enter into a formal agreement, or to acquire an illness. Related: agreement, pact, deal, covenant.
- RELAX /rɪˈlæks/ · verb
- To become less tense, anxious, or physically strained; to make oneself less tense. It can also mean to make something less strict or severe, as in relaxing a rule or restriction. Related: unwind, loosen, ease, calm.
- BICEPS /ˈbaɪsɛps/ · noun
- A large skeletal muscle at the front of the upper arm that flexes the forearm and rotates it outward; in anatomy, more precisely one of two such muscles (biceps brachii and biceps femoris). Informally, a well-developed upper-arm muscle regarded as a sign of strength. Related: muscle, brawn.
- TRICEPS /ˈtraɪsiːps/ · noun
- The triceps is the large muscle at the back of the upper arm that extends the forearm at the elbow. More generally, the term can refer to a muscle with three heads. Related: triceps brachii, triceps muscle.
