Question | Answer |
Abduction | Moving away from the midline of the body |
Actin | Contractile protein found in the myofilaments of skeleton muscle |
Adduction | Moving toward the midline of the body |
All or None | When stimulated, a muscle fiber will contract fully or not at all |
Antagonists | Those having opposing actions |
Biceps Brachii | The primary flexor of the arm |
Bursa | Small, cushion like sacs that are found between moving body parts to make it easier to move |
Deltoid | Having a triangular shape |
Duchenne Muscular Dystrophy | Form of muscular dystrophy inherited on the X chromosome and characterized by mild leg muscle weakness that progresses rapidly to include the shoulder muscles and eventually death |
Endurance Training | Continuous vigorous exercise requiring the body to increase its consumption of oxygen and develop the muscles' ability to sustain activity over a prolonged period of time |
Extension | Increasing the angle between two bones at a joint |
Fatigue | Loss of muscle power |
Flexion | the act of bending |
Hypertrophy | Increased size of a part caused by an increase in the size of its cells |
Hypothermia | Failure of thermoregulatory mechanisms to maintain homeostasis in a very cold environment |
Insertion | Attachment of muscle to the bone that it moves when contraction occurs |
Intercalated Disks | Connections that form unique dark bands between cardiac muscle fibers |
Isometric Contraction | Type of muscle contraction in which muscle does not shorten |
Isotonic Contraction | Type of muscle contraction that maintains uniform tension or pressure |
Masseter | Largest muscle of the cheek |
Mastication | Chewing |
Motor Neuron | Transmits nerve impulses from the brain and spinal cord to muscles and glandular epithelial tissues |
Muscle Fiber | The specialized contractile cells of muscle tissue that are grouped together and arranged in a highly organized way |
Muscular Dystrophy | A group of muscle disorders characterized by atrophy of skeletal muscle without nerve involvement |
Myasthenia Gravis | Autoimmune muscle disorder characterized by progressive weakness and chronic fatigue |
Myosin | Contractile protein found in the thick myofilaments of skeletal muscle |
Neuromuscular Junction | The point of contact between the nerve endings and muscle fibers |
Origin | The attachment of a muscle to a bone which does not move when contraction occurs |
Oxygen Debt | Continued increased metabolism that occurs in a cell to remove excess lactic acid that resulted from exercise |
Pectoralis Major | Major flexor of the upper arm |
Posture | Position of the body |
Prime Mover | The muscle responsible for producing a particular movement |
Rotation | Movement around a longitudinal axis |
Sarcomere | Contractile unit of muscle; length of a myofibril between two Z bands |
Sliding Filament Model | Concept in muscle physiology describing the contraction of a muscle fiber in terms of the sliding of microscopic protein filaments past each other within the myofibrils in a manner that shortens the myofibrils and thus the entire muscle |
Sprain | An acute injury to soft tissues surrounding a joint, including muscle, tendon, and/or ligament |
Strain | Injury involving any component of the “musculotendinous unit” |
Strength Training | Contracting muscles against resistance to enhance muscle hypertrophy |
Synergists | Muscle that assists a prime mover |
Tendon Sheaths | Tube-shaped structure lined with synovial membrane that encloses certain tendons |
Tendons | Bands or cords of fibrous connective tissue that attach a muscle to a bone or other structure |
Tetanus | Sustained muscular contraction |
Threshold Stimulus | Minimal level of stimulation required to cause a muscle fiber to contract |
Tonic Contraction | Special type of skeletal muscle contraction used to maintain posture |
Trapezius | Triangular muscle in the back that elevates the shoulder and extends the head backwards |
Triceps Brachii | Extensor of the elbow |
Twitch | A quick, jerky response to a single stimulus |
Zygomaticus | The corners of the mouth and lips |
Paralysis | Loss of the power of motion, especially voluntary motion |
