"Bundle of His" is formed of

Options

A. Nervous tissue supplied to ventricles
B. Nervous tissue supplied to heart
C. Muscular tissue supplied to ventricles
D. Muscular tissue supplied to heart

Answer

**Step-by-Step Solution:**

1. **Understanding the Bundle of His**: The Bundle of His, also known as the atrioventricular bundle, is a collection of heart muscle cells that play a crucial role in the electrical conduction system of the heart.

2. **Function of the Bundle of His**: Its primary function is to transmit electrical impulses from the atrioventricular (AV) node to the walls of the ventricles. This transmission is essential for coordinating the contraction of the ventricles, allowing for effective pumping of blood.

3. **Analyzing the Options**:
- **Option 1: Nervous Tissue Supplied to Ventricles**: This option is incorrect because the Bundle of His is not made of nervous tissue; it is made of muscle cells.
- **Option 2: Nervous Tissue Supplied to Heart**: This option is also incorrect for the same reason; the Bundle of His does not consist of nervous tissue.
- **Option 3: Muscular Tissue Supply to Ventricles**: This option is correct. The Bundle of His is indeed composed of muscular tissue (specifically cardiac muscle cells) that transmits electrical impulses to the ventricles.

4. **Conclusion**: Based on the analysis, the correct answer is that the Bundle of His is formed of muscular tissue that supplies the ventricles.

**Final Answer**: The Bundle of His is formed of muscular tissue.
