Incorrect Statement: The cytoplasm of striated muscle is called endoplasm.
Explanation:
Striated muscles, also known as skeletal muscles, are attached to bones and are responsible for voluntary movements of the body. They are called striated muscles because their cells exhibit a striped or striated appearance under a microscope.
Structure of Striated Muscle:
1. Muscle Fibers: Striated muscles are made up of long, cylindrical cells called muscle fibers.
2. Myofibrils: Each muscle fiber contains multiple myofibrils, which are composed of repeating units called sarcomeres.
3. Sarcomeres: Sarcomeres are the functional units of striated muscles and are responsible for muscle contraction. They contain thick filaments made of the protein myosin and thin filaments made of the protein actin.
4. Sarcolemma: The plasma membrane of striated muscle fibers is called sarcolemma. It encloses the cytoplasm and regulates the movement of substances in and out of the muscle fiber.
5. Sarcoplasmic Reticulum: The endoplasmic reticulum (ER) of striated muscle fibers is called sarcoplasmic reticulum. It is a specialized form of ER that stores and releases calcium ions, which are essential for muscle contraction.
Corrected Statement: The cytoplasm of striated muscle is called sarcoplasm.
Conclusion:
The incorrect statement is option C, which states that the cytoplasm of striated muscle is called endoplasm. In reality, the cytoplasm of striated muscle is called sarcoplasm. The sarcoplasm contains the necessary cellular components for muscle contraction, including the myofibrils, mitochondria, and other organelles. The sarcoplasmic reticulum, not the endoplasm, is responsible for storing and releasing calcium ions required for muscle contraction.
