Head of sperm is made up of

Options

A. A : Acrosome
B. B : Carvical canal
C. C : Uterine cavity
D. D : Ampulla

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of Sperm**: Sperm is composed of three main parts: the head, the neck (or middle piece), and the tail. Each part has specific functions and structures.

2. **Identifying the Components of the Head**: The head of the sperm is crucial as it contains the genetic material that will combine with the egg. Within the head, there is a specialized structure known as the acrosome.

3. **Function of the Acrosome**: The acrosome is a cap-like structure that contains enzymes necessary for penetrating the outer layers of the egg during fertilization. This makes it an essential component of the sperm's head.

4. **Evaluating the Options**: The question provides four options regarding what the head of the sperm is made up of:
- A. Acrosome
- B. Cervical canal
- C. Uterine cavity
- D. Ampulla

5. **Analyzing Each Option**:
- **Option A (Acrosome)**: This is correct as it is a part of the sperm's head.
- **Option B (Cervical canal)**: This is part of the female reproductive system, not related to the sperm.
- **Option C (Uterine cavity)**: This is also part of the female reproductive system and not related to sperm.
- **Option D (Ampulla)**: This refers to a part of the female reproductive tract and is not part of the sperm.

6. **Conclusion**: The correct answer is **Option A: Acrosome**, as it is the structure that makes up the head of the sperm.
