MICROANATOMY

Detailed explanation-1: -Sarcoplasm is the cytoplasm of a muscle cell. It is comparable to the cytoplasm of other cells, but it contains unusually large amounts of glycogen (a polymer of glucose), myoglobin, a red-colored protein necessary for binding oxygen molecules that diffuse into muscle fibers, and mitochondria.

Detailed explanation-2: -Sarcoplasm is the cytoplasm of a myocyte (muscle fiber).

Detailed explanation-3: -Complete answer: Sarcolemma is the cover or cell membrane that is present around the striated muscle fibres. The plasma membrane of muscle fibres is known as the sarcolemma and the cytoplasm is known as sarcoplasm.

Detailed explanation-4: -The sarcoplasmic reticulum (SR) is a specialized form of the endoplasmic reticulum of muscle cells, dedicated to calcium ion (Ca2+) handling, necessary for muscle contraction and relaxation.

Detailed explanation-5: -The sarcolemma is the plasma membrane of the muscle cell and is surrounded by basement membrane and endomysial connective tissue.
