MICROANATOMY

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: -Sarcoplasm: it is the cytoplasm (material or protoplasm within a living cell, excluding the nucleus) of striated 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.

Detailed explanation-5: -Ontogenesis of Striated Muscle The abundant sarcoplasm (i.e., cytoplasm) within the core of the myotube between and around nuclei contains membranous organelles. These are mitochondria with well-formed cristae, Golgi apparatuses generally located at the end of a nucleus, and single-membrane vesicles.
