Sarcoplasm is described as

• A. Cytoplasm
• B. Interstitial fluid
• C. Sarcoplasm
• D. Nucleoplasm

Answer: (C)

Sarcoplasm is the muscle cell’s own version of cytoplasm. It refers to the fluid inside a muscle fiber, bounded by the cell membrane, where the cytosol and organelles like mitochondria and glycogen stores reside. In muscle tissue this specialized cytoplasm is called sarcoplasm, so describing it as the cytoplasm of a muscle cell is the precise way to express what it is. It’s separate from interstitial fluid, which sits between cells in tissue, and from nucleoplasm, which is the substance inside the cell nucleus.
