Vasa efferentia end in and vasa deferentia start from the following regions of epididymis respetively.

Options

A. Caput epididymis & cauda epididymis
B. Caput epididymis & carpus epididymis
C. Cauda epididymis & caput epididymis
D. Cauda epididymis & carpus epididymis

Answer

**Step-by-Step Solution:**

1. **Understand the Structure of the Epididymis:**
- The epididymis is divided into three main segments: the caput (head), corpus (body), and cauda (tail).

2. **Identify the Function of Vasa Efferentia:**
- Vasa efferentia are the ducts that transport sperm from the testis to the epididymis. They connect to the epididymis at the caput region.

3. **Determine Where Vasa Efferentia End:**
- The vasa efferentia end in the caput of the epididymis. This is where the sperm enters the epididymis.

4. **Identify the Function of Vasa Deferentia:**
- The vasa deferentia (or ductus deferens) are the ducts that transport sperm from the epididymis to the ejaculatory duct.

5. **Determine Where Vasa Deferentia Start:**
- The vasa deferentia start from the cauda region of the epididymis. This is where the sperm is stored and matures before being transported.

6. **Conclude the Answer:**
- Therefore, the vasa efferentia end in the caput of the epididymis, and the vasa deferentia start from the cauda of the epididymis.

**Final Answer:**
- Vasa efferentia end in the caput epididymis and vasa deferentia start from the cauda epididymis.
