Muscles are held in place and covered by: endomysium fascia tendons sarcomeres 3. A change in length of extrafusal muscle fibers to allow CNS to control posture, reflexes, opposing muscle groups, and a change in tension on collagen fibers to allow CNS to inhibit motor neurons to prevent injury. Finally, immerse yourself in the process of the sliding filament theory by interacting with the contractile proteins of a sarcomere. increased ca2+ binds troponin, which displaces tropomyosin, thus exposing myosin binding site. There are three major types of muscle tissues in the human body: skeletal, smooth, and cardiac muscle tissues. The breakdown of ATP is important because once ATP binds, the myosin head lets go of the actin . All myofibers in the unit contract at once. sirena. The three types of skeletal muscle fibers are slow red oxidative fibers, fast intermediate oxidative-glycolytic fibers and fast white glycolytic fibers. Skeletal Muscle Tissue has very large cylindrical cells (muscle fibers); striated; many nuclei found along the edge of the cell skeletal muscle fiber striated Unique features of smooth muscle cells are that it stretches wihtout developing tension which is important for the bladder and the stomach. the enzyme that breaks down acetylcholine in the synaptic cleft, during repolarization the cell cannot be stimulated again until repolarization is complete, the force exerted by a contracting muscle on an object, the opposing force exerted on the muscle by the weight of the object to be moved, A motor neuron and all of the muscle fibers it innervates, a chart of the timing and strength of a muscle's contraction, the response of a muscle to a single stimulation, the first few milliseconds following stimulation when excitation-contraction coupling is occuring; during this period, muscle tension is beggining to increase, cross bridges are active, from the onset to the peak of tension development, and the myogram tracing rises to a peak, final phase, lasting 10-100ms, is initiated by reentry of Ca2+ into the SR; muscle tension decreases to zero and tracing returns to baseline, depends on tension produced by each fiber and number of fibers contracting, if two identical stimuli (electrical shocks or nerve impulses) are delivered to muscle in rapid succession, the second twitch will be stronger then the first; this occurs because second contraction occurs before the muscle has completely relaxed; primary function is to produce smooth continuous muscle cells, some relaxation occurs between contractions, but nerve stimuli arrive at an even faster rate than during summing of contractions, unless the muscle contraction is smooth and sustained, No evidence of relaxation before the following contractions depolarization of sarcolemma causes increased cytoplasmic ca2+ from SR (via GPCR) and extracellular fluid (via voltage-gated channel).
