instructions
sarcolemma
muscle fiber
sarcoplasm
sarcoplasmic reticulum
t-tubule
narrow, tubular extensions of the sarcolemma into the sarcoplasm
plasma membrane of a muscle fiber
smooth endoplasmic reticulum in a muscle fiber
a muscle cell
cytoplasm of a muscle fiber

Explanation:

• Sarcolemma: It is the plasma membrane of a muscle fiber.
• Muscle fiber: A muscle fiber is a muscle cell.
• Sarcoplasm: The sarcoplasm is the cytoplasm of a muscle fiber.
• Sarcoplasmic reticulum: It is the smooth endoplasmic reticulum in a muscle fiber.
• T - tubule: T - tubules are narrow, tubular extensions of the sarcolemma into the sarcoplasm.

Answer:

• Sarcolemma: plasma membrane of a muscle fiber
• Muscle fiber: a muscle cell
• Sarcoplasm: cytoplasm of a muscle fiber
• Sarcoplasmic reticulum: smooth endoplasmic reticulum in a muscle fiber
• T - tubule: narrow, tubular extensions of the sarcolemma into the sarcoplasm
