Loop of Henle is part of
(a) Uriniferous tubule
(b) Seminiferous tubule
(c) Neuron
(d) Muscle fibres

Options

A. Uriniferous tubule
B. Seminiferous tubule
C. Neuron
D. Muscle fibres

Answer

### Step-by-Step Solution

1. **Understanding the Question**: The question asks about the anatomical structure that the Loop of Henle is part of.

2. **Identifying the Options**: The options provided are:
- (a) Uriniferous tubule
- (b) Seminiferous tubule
- (c) Neuron
- (d) Muscle fibres

3. **Defining the Loop of Henle**: The Loop of Henle is a U-shaped part of the nephron, which is the functional unit of the kidney. It plays a crucial role in the concentration of urine.

4. **Identifying the Nephron Structure**: The nephron consists of several parts:
- Renal corpuscle (which includes Bowman's capsule and glomerulus)
- Proximal convoluted tubule
- Loop of Henle
- Distal convoluted tubule
- Collecting duct

5. **Analyzing Each Option**:
- **Option (a) Uriniferous tubule**: This is correct because the Loop of Henle is part of the nephron, which is also referred to as the uriniferous tubule.
- **Option (b) Seminiferous tubule**: This is incorrect; seminiferous tubules are involved in sperm production in the testes.
- **Option (c) Neuron**: This is incorrect; neurons are nerve cells and not related to the urinary system.
- **Option (d) Muscle fibres**: This is incorrect; muscle fibers are involved in muscle contraction and are not related to the urinary system.

6. **Conclusion**: Based on the analysis, the correct answer is (a) Uriniferous tubule.

### Final Answer
The Loop of Henle is part of (a) Uriniferous tubule.
