Samuel Johnson's Dictionary

  1. MUSCLEnoun

    Muscle is a bundle of thin and parallel plates of fleshy threads or fibres, inclosed by one common membrane: all the fibres of the same plate are parallel to one another, and tied together at extremely little distances by short and transverse fibres: the fleshy fibres are composed of other smaller fibres, inclosed likewise by a common membrane: each lesser fibre consists of very small vesicles or bladders, into which we suppose the veins, arteries and nerves to open, for every muscle receives branches of all those vessels, which must be distributed to every fibre: the two ends of each muscle or the extremities of the fibres are, in the limbs of animals, fastened to two bones, the one moveable, the other fixed; and therefore, when the muscles contract, they draw the moveable bone according to the direction of their fibres. John Quincy

    Etymology: muscle, Fr. musculus, Lat. muscula , Sax.

    The instruments of motion are the muscles, the fibres whereof, contracting themselves, move the several parts of the body. John Locke.

  1. muscle

    Skeletal muscles (commonly referred to as muscles) are organs of the vertebrate muscular system and typically are attached by tendons to bones of a skeleton. The muscle cells of skeletal muscles are much longer than in the other types of muscle tissue, and are often known as muscle fibers. The muscle tissue of a skeletal muscle is striated – having a striped appearance due to the arrangement of the sarcomeres. Skeletal muscles are voluntary muscles under the control of the somatic nervous system. The other types of muscle are cardiac muscle which is also striated and smooth muscle which is non-striated; both of these types of muscle tissue are classified as involuntary, or, under the control of the autonomic nervous system.A skeletal muscle contains multiple fascicles – bundles of muscle fibers. Each individual fiber, and each muscle is surrounded by a type of connective tissue layer of fascia. Muscle fibers are formed from the fusion of developmental myoblasts in a process known as myogenesis resulting in long multinucleated cells. In these cells the nuclei termed myonuclei are located along the inside of the cell membrane. Muscle fibers also have multiple mitochondria to meet energy needs. Muscle fibers are in turn composed of myofibrils. The myofibrils are composed of actin and myosin filaments called myofilaments, repeated in units called sarcomeres, which are the basic functional, contractile units of the muscle fiber necessary for muscle contraction. Muscles are predominantly powered by the oxidation of fats and carbohydrates, but anaerobic chemical reactions are also used, particularly by fast twitch fibers. These chemical reactions produce adenosine triphosphate (ATP) molecules that are used to power the movement of the myosin heads.


  1. muscle

    A muscle is a type of soft tissue in animals that produces force and motion. It is characterized by its ability to contract, generally in response to neurological stimuli. Muscles are essential for bodily functions such as locomotion, maintaining posture, and controlling bodily movements including heart contraction, swallowing, and breathing.

Webster Dictionary

  1. Musclenoun

    an organ which, by its contraction, produces motion

  2. Musclenoun

    the contractile tissue of which muscles are largely made up

  3. Musclenoun

    muscular strength or development; as, to show one's muscle by lifting a heavy weight

  4. Musclenoun

    see Mussel

  5. Etymology: [F., fr. L. musculus a muscle, a little mouse, dim. of mus a mouse. See Mouse, and cf. sense 3 (below).]


  1. Muscle

    Muscle is a soft tissue found in most animals. Muscle cells contain protein filaments that slide past one another, producing a contraction that changes both the length and the shape of the cell. Muscles function to produce force and motion. They are primarily responsible for maintenance of and changes in posture, locomotion of the organism itself, as well as movement of internal organs, such as the contraction of the heart and movement of food through the digestive system via peristalsis. Muscle tissues are derived from the mesodermal layer of embryonic germ cells in a process known as myogenesis. There are three types of muscle; classified as skeletal, cardiac, or smooth muscles. These types of muscles are split down into two more different classifications: voluntary and involuntary. Cardiac and smooth muscle contraction muscles occur without conscious thought and are thought to be essential for survival. Muscles are predominantly powered by the oxidation of fats and carbohydrates, but anaerobic chemical reactions are also used, particularly by fast twitch fibers. These chemical reactions produce adenosine triphosphate molecules which are used to power the movement of the myosin heads.

Chambers 20th Century Dictionary

  1. Muscle

    mus′l, n. an animal tissue consisting of bundles of fibres through whose contractility bodily movement is effected, the fibres of the voluntary muscles being striped, those of the involuntary (of intestinal canal, blood-vessels, and of skin) unstriped.—adj. Mus′cled, supplied with muscles.—ns. Mus′cle-read′ing, the interpretation of slight involuntary muscular movements; Mus′cling, the delineation of muscles, as in a picture; Musculā′tion, the arrangement of muscles of a body; Musculos′ity.—adj. Mus′culous, pertaining to muscle: full of muscles, strong. [Fr.,—L. musculus, dim. of mus, a mouse, a muscle.]

Examples of Muscle in a Sentence

  1. Eric Butterworth:

    Nothing stops the man who desires to achieve. Every obstacle is simply a course to develop his achievement muscle. It's a strengthening of his powers of accomplishment.

  2. Peter Drucker:

    Management means, in the last analysis, the substitution of thought for brawn and muscle, of knowledge for folkways and superstition, and of cooperation for force. It means the substitution of responsibility for obedience to rank, and of authority of performance for the authority of rank. Whenever you see a successful business, someone once made a courageous decision.

  3. Martin Hoffman:

    When someone runs 26 miles, the blood supply to the skin and muscle increases tremendously, because they need a lot of oxygen, it's estimated that up to 25% of blood ends up going to skin and muscle, and when this happens, that means the blood is getting diverted from other organs. So, while the skin and muscle are perfused at a higher rate, the kidneys are receiving a reduced blood supply.

  4. Thomas Carlyle:

    A man with a half volition goes backwards and forwards, and makes no way on the smoothest road a man with a whole volition advances on the roughest, and will reach his purpose, if there be even a little worthiness in it. The man without a purpose is like a ship without a rudder - a waif, a nothing, a no man. Have a purpose in life and having it, throw such strength of mind and muscle into your work as God has given you.

  5. Rita Rudner:

    I got kicked out of ballet class because I pulled a groin muscle. It wasn't mine.
