Malpighian corpuscle is

Options

A. An excretory structure of insect
B. Another name for a nephron
C. Common name for glomerulus and Bowman's capsule
D. Present in medulla of kidney

Answer

**Step-by-Step Solution:**

1. **Understanding the Term "Malpighian Corpuscle":**
- The Malpighian corpuscle is a term that refers to a specific structure within the nephron of the kidney. It is not an excretory structure of insects, nor is it another name for the nephron itself.

2. **Components of the Malpighian Corpuscle:**
- The Malpighian corpuscle consists of two main parts:
- **Glomerulus:** A network of capillaries that plays a crucial role in the filtration of blood.
- **Bowman’s Capsule:** A cup-shaped structure that encases the glomerulus and collects the filtrate that is produced during the filtration process.

3. **Function of the Malpighian Corpuscle:**
- The primary function of the Malpighian corpuscle is ultrafiltration. Blood enters the glomerulus, where pressure forces water and small solutes out of the blood and into the Bowman’s capsule, forming a filtrate.

4. **Relation to Nephrons:**
- The Malpighian corpuscle is often referred to as the renal corpuscle or Malpighian body, and it is a crucial part of the nephron, which is the functional unit of the kidney.

5. **Conclusion:**
- Therefore, the correct description of the Malpighian corpuscle is that it is a structure formed by the glomerulus and Bowman’s capsule, responsible for the initial step in urine formation through ultrafiltration.

**Final Answer:**
The Malpighian corpuscle is a structure in the nephron of the kidney, consisting of the glomerulus and Bowman’s capsule, responsible for ultrafiltration.
