ANATOMY

Detailed explanation-1: -Sarcoplasm is the cytoplasm of a muscle fibre. It is a water solution containing ATP and phosphagens, as well as the enzymes and intermediate and product molecules involved in many metabolic reactions. The most abundant metal in the sarcoplasm is potassium.

Detailed explanation-2: -Sarcoplasm is the cytoplasm of a myocyte (muscle fiber). It is comparable to the cytoplasm of other cells, but it contains unusually large amounts of glycosomes (granules of stored glycogen) and significant amounts of myoglobin, an oxygen-binding protein.

Detailed explanation-3: -We can understand more about the plasma membrane of the muscle cells. As mentioned earlier, the plasma membrane of a skeletal muscle fiber is called the sarcolemma. The sarcolemma invaginates into the cytoplasm of the muscle cell (sarcoplasm). This forms membranous tubules that pass across the muscle cells.

Detailed explanation-4: -The sarcolemma is the plasma membrane of the muscle cell and is surrounded by basement membrane and endomysial connective tissue. The sarcolemma is an excitable membrane and shares many properties with the neuronal cell membrane.

Detailed explanation-5: -The cytoplasm of a muscle fiber is called sarcoplasm. Sarcoplasm is different from the cytoplasm of other cells in that it contains large amounts of myoglobin and glycosomes, both of which reflect the high energy demands of muscle fibers.
