Ejacaiatory duct is formed by union of

Options

A. Duct from seminal vesicle, vas deferens and glandular part of urethra
B. Duct from prostate gland and membranous urethra
C. Duct from seminal vesicle and vas deferens
D. Duct from Cowper`s gland and penile urethra

Answer

To solve the question regarding what the ejaculatory duct is formed by, we can break it down into clear steps:

### Step-by-Step Solution:

1. **Understanding the Ejaculatory Duct**:
- The ejaculatory duct is a crucial structure in the male reproductive system that plays a role in the transport of sperm.

2. **Identifying the Components**:
- The ejaculatory duct is formed by the union of two specific ducts: the duct of the seminal vesicle and the vas deferens.

3. **Analyzing the Options**:
- **Option 1**: Duct from seminal vesicle, vas deferens, and glandular part of urethra.
- This option is incorrect because the ejaculatory duct does not include the glandular part of the urethra.
- **Option 2**: Duct from prostate gland and membranous urethra.
- This option is also incorrect because the prostate gland does not directly form the ejaculatory duct.
- **Option 3**: Duct from seminal vesicle and vas deferens.
- This option is correct as it accurately describes the components that form the ejaculatory duct.
- **Option 4**: Duct from Cowper's gland and penile urethra.
- This option is incorrect because Cowper's gland (bulbourethral gland) does not contribute to the formation of the ejaculatory duct.

4. **Conclusion**:
- The correct answer is that the ejaculatory duct is formed by the union of the duct from the seminal vesicle and the vas deferens.

### Final Answer:
The ejaculatory duct is formed by the union of the duct from the seminal vesicle and the vas deferens.
