Options

A. Corpus cavernosa
B. Corpus spongiosum
C. Both
D. None

Answer

To answer the question "Bundles of erectile tissues in the penis are," we need to identify the types of erectile tissues present in the penis. Here’s the step-by-step solution:

### Step 1: Identify the Types of Erectile Tissues
The penis contains three main types of erectile tissues:
1. **Corpus Cavernosum** (two bundles)
2. **Corpus Spongiosum** (one bundle)

### Step 2: Understand the Function of Each Tissue
- **Corpus Cavernosum**: These are two cylindrical structures that run along the length of the penis. They are responsible for the rigidity of the penis during erection by filling with blood and compressing the veins to slow blood outflow.
- **Corpus Spongiosum**: This single structure surrounds the urethra and prevents it from collapsing during erection. It also contributes to the overall volume of the penis during arousal.

### Step 3: Analyze the Options Provided
The options given are:
1. Corpus Cavernosum
2. Corpus Spongiosum
3. Both
4. None

Based on our understanding:
- Both the **Corpus Cavernosum** and **Corpus Spongiosum** are present in the penis.

### Step 4: Conclusion
Since both types of erectile tissues are present in the penis, the correct answer is:
**Option 3: Both**
