WebOct 7, 2024 · dreamrob Answer: In a muscle fiber Ca+ + is stored in Sarcoplasmic reticulum. When muscle cells are stimulated the calcium ions are released inside the sarcoplasmic reticulum. Sarcoplasmic reticulum is a membrane-bound arrangement found in muscle cells. WebThe signal for a muscle to contract originates in the nervous system and is transmitted to the muscle at the neuromuscular junction, a point of contact between the motor nerve and the muscle. In higher organisms each muscle fibre is innervated by a single motor nerve fibre; in other species (e.g., crustaceans) inhibitory fibres are also present.

Web- Ca++ is released from lateral sacs--> Ca++ binds to troponin, conformational charge in tropomyosin, now MCB can bind to actin . 100. What are the types of muscle fibers? Type I . Type IIa . Type IIx . 100. What is atrophy? if muscle are not used the actin and myosin content decreases and muscle decreases in mass . 100. WebThe muscle fiber will repolarize, which closes the gates in the SR where Ca ++ was being released. ATP-driven pumps will move Ca ++ out of the sarcoplasm back into the SR. This results in the “reshielding” of the actin-binding sites on the thin filaments.
Web• Ca++ release from T- tubules, which are large, is a very important source of Ca++. • T-tubule Ca++ depends strongly on extracellular Ca++ concentration. • Heart’s T-tubules are bigger than those in skeletal muscle and rich in mucopolysaccharides. • Mucopolysaccharides bind and store Ca++.
