GENERAL HISTOLOGY

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: -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. These are called transverse tubules (or ‘T tubules’).

Detailed explanation-3: -This is muscle cell. The lining over muscle fibre is called sarcolemma. The protoplasm in the muscle fibre is called sarcoplasm. The endoplasmic reticulum in muscle fibre is called sarcoplasmic reticulum.

Detailed explanation-4: -sarcoplasm: The cytoplasm of a myocyte. sarcoplasmic reticulum: The equivalent of the smooth endoplasmic reticulum in a myocyte. sarcolemma: The cell membrane of a myocyte. sarcomere: The functional contractile unit of the myofibril of a striated muscle.
