Neurilemma is outer covering of

Options

A. Blood capillaries
B. Muscle fibre
C. Intestine
D. Nerve fibre.

Answer

**Step-by-Step Solution:**

1. **Understanding Neurilemma**: Neurilemma, also known as the neurolemma, is a specific structure associated with nerve cells. It is the outermost layer of the nerve fibers.

2. **Identifying the Function**: The primary function of the neurilemma is to serve as a protective covering for the axons of neurons. It plays a crucial role in the regeneration of nerve fibers.

3. **Relation to Myelin Sheath**: The neurilemma is located outside the myelin sheath, which is another protective layer that surrounds the axons. The myelin sheath is made up of modified cellular membranes.

4. **Conclusion on the Outer Covering**: Since the neurilemma surrounds the axons of neurons and is the outer covering of nerve fibers, we can conclude that the correct answer to the question is that the neurilemma is the outer covering of nerve fibers.

5. **Elimination of Incorrect Options**: The other options provided (blood capillaries, muscle fibers, and intestines) do not relate to the structure of the neurilemma, confirming that the correct answer is indeed related to nerve fibers.

**Final Answer**: Neurilemma is the outer covering of nerve fibers.
