An anchoring protein for actin, coextend with actin and appears to play a regulatory role in mediating actin and myosin interactions.
Connective tissue sheath surrounding each fasciculus
A plasma membrane surrounding individual muscle fibers.
The motor units within a given muscle appear to be ranked.
The process by which the tension of a given motor unit can vary from that of a twitch to that of tetanus by increasing the frequency of stimulation of that motor unit.
Composed of the plasmalemma and the basement membrane.
The basic funtional unit of a myofibril and the basic contractile unit of muscle.
A gelatin-like substance that fills the spaces between and within the myofibrils.
A longitudinal network of tubules found within the muscle fiber.
Located between the plasmalemma and the basement membrane.
Involved in growth development of skeletal muscle and muscle's adaptation to injury, immobilization, and training.
A mechanism that may partially explain the principle of orderly recruitment.
When the myosin cross-bridges are activated they bind with actin, resulting in a conformational change in the cross-bridge, which causes the myosin head to tilt and to drag the thin filament toward the center of the sarcomere.
Muscles acting without moving. Happens when the muscle generates force but its length remains static (unchanged).
A series of three stimuli in rapid sequence, prior to complete relaxation from the first stimulus, can elicit an even greater increase in for or tension.
A state of continued stimulation at higher frequencies.
Stabilizes the myosin filaments along their longitudinal axis. They are filaments that extend from the Z-disk to the M-line.
Extensions of the plasmalemma that pass laterally through the muscle fiber. Allowing nerve impulses received by the plasmalemma to be transmitted rapidly to individual myofibrils.
One of Three Protein molecules that make each actin filament.
One of Three Protein molecules that make each actin filament.
The smallest contractile response of a muscle fiber or a motor unit to a single electrical stimulus.
Muscle fiber that takes 110 ms to reach peak tension in stimulation.
Muscle fiber that takes 50 ms to reach peak tension in stimulation.
What thinner filaments are composed primarily of.
Arrives at the a-motor neuron's dendrites, specialized receptors on the neuron's cell body.
Located on the myosin head, splits the ATP to yield ADP, inorganic phosphate, and energy.
Molecule that binds with myosin for muscle contraction to occur because ATP supplies needed energy.
When there is joint movement is produced, concentric contractions are considered dynamic.
The action of muscles exerting force even while lengthening.
A sheath of connective tissue that covers each muscle fiber.
The complex sequence of events that triggers a muscle fiber to contract.
Small bundles of fibers wrapped in a connective tissue sheath.
A single a-motor neuron and all the muscle fibers it directly signals are collectively a motor unit.
each fiber is a muscle cell that are multinucleated.
Skeletal muscles and the bones of the skeleton make up this system
Small fibers made up of the basic contractile elements of skeletal muscle- the sarcomeres.
What the thicker filaments are made of primarily.
