Sarcoplasm
The Sarcoplasm of a muscle fiber is comparable to the cytoplasm of other cells, but it houses unusually large amounts of glycosomes (granules of stored glycogen) and significant amounts of myoglobin, an oxygen binding protein.1

What does sarcoplasmic reticulum do?

The Sarcoplasmic Retiulum releases calcium ions that will cause troponin/tropomyosin complex to move. This exposes the binding sites on actin and allows the cross-bridges of myosin to bind to the actin binding sites.

What is the major function of the sarcoplasmic reticulum in muscle contraction?

The major function of the sarcoplasmic reticulum in musclecontraction is to regulate intracellular calcium concentration. Itis a system of membrane-bound tubules that surrounds the musclefibrils. it is a specialized form of smooth endoplasmic reticulum.The calcium ions initiates and promotes the att ( Full Answer )

What is an increase in the diameter of muscle fibers owing to the production of more myofibrils mitochondria sarcoplasmic reticulum and so forth?

Muscular Hypertrophy is the increase in muscle size due toincreased number of myofibrils et al. . Each muscle fiber (myocyte syncytium) consists of a cellmembrane (sarcolemma) containing myofilaments actin and myosinarranged in end to end segments called sarcomeres. Muscle fibersare produced by fu ( Full Answer )

What is the function of the sarcoplasm?

The sarcoplasm is the cytoplasm or intracellular fluid of a muscle cell. It has many functions in acting as a medium for various cellular reactions to take place which are necessary for muscle contraction and general cellular metabolism.

What is the major function of the sarcoplasmic reticulum in skeletal muscle contraction?

Sarcoplasmic reticulum is the endoplasmic reticulum of the muscle cell it contains calcium ions in it and the calcium ions are responsible for the contraction of the muscle At the time when the nerve signal reaches the neuromuscular junction i.e. the site at which neuron and the muscle membranes me ( Full Answer )

Major function of the sarcoplasmic reticulum?

One major function of the sarcoplasmic reticulum is the regulatethe intracellular levels of CA2+ for contractions and relaxationfor muscles. Sarcoplasmic Reticulum is a storage organelle withcalcium ion pumps on membrane and use ATP to fuel pumps to getcalcium ion inside it's cell and holds it. When ( Full Answer )

What causes the release of calcium ions from the sarcoplasmic reticulum?

When Ach enters the synaptic cleft (gap) it open chemically gated sodium channels that starts an action potential spreading through the sarcolemma of the myofibril. This action potential spreads down the T-tubules and "shocks" the sarcoplasmic reticulum into releasing calcium ions.
