Foot cells are

Options

A. Podocytes of Bowmans capsule
B. JG cells of affarent arteriole
C. Macula densa of efferent arteriole
D. Macula densa of DCT

Answer

To answer the question "Foot cells are?", we will analyze the options provided and identify which one correctly describes foot cells.

### Step-by-Step Solution:

1. **Understanding the Term "Foot Cells":**
- Foot cells refer to specialized cells that have extensions resembling feet. In the context of the excretory system, these are typically associated with the renal corpuscle.

2. **Analyzing Option 1: Podocytes of the Bowman's Capsule:**
- Podocytes are specialized epithelial cells found in the Bowman's capsule of the nephron in the kidney.
- They have long, finger-like projections called foot processes (or pedicels) that interdigitate with each other, forming filtration slits.
- This structure is crucial for the filtration of blood, making podocytes the correct answer.

3. **Analyzing Option 2: JG Cells of the Afferent Arteriole:**
- Juxtaglomerular (JG) cells are located in the walls of the afferent arterioles and are involved in regulating blood pressure by releasing renin.
- They do not have the foot-like extensions characteristic of podocytes. Therefore, this option is incorrect.

4. **Analyzing Option 3: Macula Densa of the Efferent Arteriole:**
- The macula densa is a group of specialized epithelial cells located in the distal convoluted tubule, not the efferent arteriole.
- It plays a role in sensing sodium concentration but does not have foot-like processes. Hence, this option is also incorrect.

5. **Analyzing Option 4: Macula Densa of the Distal Convoluted Tubule:**
- Similar to the previous option, the macula densa consists of specialized epithelial cells that monitor sodium levels.
- These cells do not have foot-like extensions, making this option incorrect as well.

6. **Conclusion:**
- Based on the analysis, the only correct option that describes foot cells is **Option 1: Podocytes of the Bowman's Capsule**.

### Final Answer:
**Foot cells are Podocytes of the Bowman's Capsule.**
