  • Muscle contraction
    Muscle contraction is the activation of tension-generating sites within muscle fibers.
  • Muscle tissue
    Muscle tissue is a soft tissue that composes muscles in animal bodies, and gives rise to muscles' ability to contract.
  • Hypertrophy
    Hypertrophy (IPA /haɪˈpɝːtrəfi/, from Greek ὑπέρ "excess" + τροφή "nourishment") is the increase in the volume of an organ or tissue due to the enlargement of its component cells.
  • Cardiac muscle cell
    Cardiac muscle cells or cardiomyocytes (also known as myocardiocytes or cardiac myocytes) are the muscle cells (myocytes) that make up the cardiac muscle.
  • Iris dilator muscle
    The iris dilator muscle (pupil dilator muscle, pupillary dilator, radial muscle of iris, radiating fibers), is a smooth muscle of the eye, running radially in the iris and therefore fit as a dilator.
  • Muscular system
    The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles.
  • Sphincter
    A sphincter is a circular muscle that normally maintains constriction of a natural body passage or orifice and which relaxes as required by normal physiological functioning.
  • Sarcomere
    A sarcomere (Greek sarx "flesh", meros "part") is the basic unit of striated muscle tissue.
  • Smooth muscle tissue
    Smooth muscle is an involuntary non-striated muscle.
  • Iris sphincter muscle
    The iris sphincter muscle (pupillary sphincter, pupillary constrictor, circular muscle of iris, circular fibers) is a muscle in the part of the eye called the iris.
  • Galvanism
    In biology, galvanism is the contraction of a muscle that is stimulated by an electric current.
  • Muscle
    Muscle is a soft tissue found in most animals.
  • Cardiac muscle
    Cardiac muscle (heart muscle) is an involuntary, striated muscle that is found in the walls and histological foundation of the heart, specifically the myocardium.
  • T-tubule
    A T-tubule (or transverse tubule) is a deep invagination of the sarcolemma, which is the plasma membrane of skeletal muscle and cardiac muscle cells.
  • Myotoxin
    Myotoxins are small, basic peptides found in snake venoms, (e.g. rattlesnakes), and lizard venoms (e.g. mexican beaded lizard).
  • Extensor expansion
    An extensor expansion (dorsal expansion, dorsal hood, dorsal aponeurosis) is the special connective attachments by which the extensor tendons insert into the phalanges.
  • Epimysium
    Epimysium (plural epimysia) (Greek epi- for on, upon, or above + Greek mys for muscle) The epimysium is the fibrous tissue envelope that surrounds skeletal muscle.
  • Hypothenar eminence
    The hypothenar muscles are a group of three muscles of the palm that control the motion of the little finger.
  • Extrafusal muscle fiber
    Extrafusal muscle fibers are the skeletal standard muscle fibers that are innervated by alpha motor neurons and generate tension by contracting, thereby allowing for skeletal movement.
  • Muscle fascicle
    In anatomy, a muscle fascicle is a bundle of skeletal muscle fibers surrounded by perimysium, a type of connective tissue.
  • Nuclear bag fiber
    A nuclear bag fiber is a type of intrafusal muscle fiber that lies in the center of a muscle spindle.
  • Nuclear chain fiber
    A nuclear chain fiber is a specialized sensory organ contained within a muscle.
  • Striated muscle tissue
    Striated muscle tissue is muscle tissue that features repeating functional units called sarcomeres, in contrast with smooth muscle tissue which does not.
  • Conjoint tendon
    The conjoint tendon (previously known as the inguinal aponeurotic falx) is a structure formed from the lower part of the common aponeurosis of the internal abdominal oblique and the transverse abdominal as it inserts into the crest of the pubis and pectineal line immediately behind the superficial inguinal ring.
  • Perimysium
    Perimysium is a sheath of connective tissue that groups muscle fibers into bundles (anywhere between 10 and 100 or more) or fascicles.
  • Modiolus (face)
    In facial anatomy, the modiolus is a chiasma of facial muscles held together by fibrous tissue, located lateral and slightly superior to each angle of the mouth.
  • Pennate muscle
    A pennate or pinnate muscle (also called a penniform muscle) is a muscle with fascicles that attach obliquely (in a slanting position) to its tendon.
  • Endomysium
    The endomysium, meaning within the muscle, is a wispy layer of areolar connective tissue that ensheaths each individual myocyte (muscle fiber, or muscle cell).
  • Axillary space
    The axillary space is an anatomic space, bounded by teres major muscle, teres minor muscle and humerus.
  • Interfoveolar ligament
    Lateral to the inguinal aponeurotic falx (i.e. the conjoint tendon) is a ligamentous band connected with the lower margin of the transversalis fascia and extending down in front of the inferior epigastric artery to the superior ramus of the pubis; it is termed the interfoveolar ligament of Hesselbach and sometimes contains a few muscular fibers.
  • Intrafusal muscle fiber
    Intrafusal muscle fibers are skeletal muscle fibers that serve as specialized sensory organs (proprioceptors) that detect the amount and rate of change in length of a muscle.
