Covering membrane around muscle fibre is known asa)Neurilemmab)Plasmalemmac)Sarcolemmad)MyolemmaCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

The sarcolemma is the cell membrane of the striated muscle fibre cell. It is also known as the myolemma. The function of the sarcolemma is similar to the function of the plasma membrane of eukaryotic cells. The plasma membrane covering the muscle fibre is known as the sarcolemma.

Answer

The covering membrane around muscle fibre is known as Sarcolemma.Explanation:- Muscle Fibres: Muscle fibres are the individual muscle cells that make up the skeletal muscle tissue. These fibres are long, cylindrical, and multinucleated.- Sarcolemma: The sarcolemma is the plasma membrane that surrounds each muscle fibre. It plays a crucial role in the proper functioning and protection of the muscle cell. - Function: The sarcolemma is responsible for conducting electrical signals or action potentials, which are essential for muscle contraction. It also helps to maintain the structural integrity of the muscle fibre and acts as a barrier between the muscle cell and its external environment. - Composition: The sarcolemma is a phospholipid bilayer membrane, similar to other cell membranes. It contains proteins, lipids, and carbohydrates that allow for the passage of ions, nutrients, and waste products in and out of the muscle cell.In summary, the sarcolemma is the covering membrane around muscle fibres, playing a crucial role in muscle function and protection.

Answer

Sarcolemma as the covering membrane of muscle fibre

The covering membrane around muscle fibre is known as the sarcolemma. The sarcolemma is a plasma membrane that surrounds each muscle fibre, also known as a muscle cell. The sarcolemma is a vital component of the muscle cell as it serves several important functions.

Functions of sarcolemma

1. Maintains the structural integrity of muscle fibre: The sarcolemma provides a protective barrier around the muscle fibre, which helps to maintain its structural integrity. It protects the internal components of the muscle cell from damage and prevents the loss of essential cellular materials.

2. Regulates the transport of substances: The sarcolemma is selectively permeable, which means that it regulates the transport of substances in and out of the muscle cell. This function is essential for muscle contraction, as it allows ions such as calcium, sodium, and potassium to enter and exit the muscle cell as required.

3. Allows for the generation of action potentials: The sarcolemma plays a crucial role in the generation of action potentials, which are electrical signals that enable muscle contraction. The sarcolemma contains ion channels that allow for the movement of ions across the membrane, which generates the electrical signals required for muscle contraction.

4. Provides attachment points for muscle proteins: The sarcolemma provides attachment points for the muscle proteins actin and myosin, which are essential for muscle contraction. The sarcolemma anchors these proteins to the muscle cell, allowing them to work together to generate force and movement.

Conclusion

In conclusion, the sarcolemma is a vital component of the muscle cell, serving several important functions that are essential for muscle contraction. It is a selectively permeable membrane that regulates the transport of substances, allows for the generation of action potentials, and provides attachment points for muscle proteins.

Answer

The plasma membrane covering of the muscle fibre is called as. 'The plasma membrane covering of the muscle fibre is called as' sarcolemma. Sarcoplasmic reticulum.

Answer

Sarcolemma is also called the myolemma and is the cell membrane of a striated muscle fibre cell and also covering membrane around the muscle fibre named as Sarcolemma. The function of Sarcolemma is same as that of the plasma membrane of Eukaryotic cells.
