Inter-calated discs are present in

Options

A. Cardiac muscles
B. Striped muscles
C. Unstriated muscles
D. Ligament .

Answer

### Step-by-Step Solution:

1. **Identify the Types of Muscle Tissue**:
- There are three main types of muscle tissues: skeletal muscle, smooth muscle, and cardiac muscle.

2. **Examine the Characteristics of Each Muscle Type**:
- **Skeletal Muscle**: These muscles are striated (striped appearance) and are under voluntary control. They do not have intercalated discs.
- **Smooth Muscle**: These muscles are non-striated (smooth appearance) and are involuntary. They also do not have intercalated discs.
- **Cardiac Muscle**: These muscles are striated and involuntary. They are found in the heart and are characterized by the presence of intercalated discs.

3. **Define Intercalated Discs**:
- Intercalated discs are specialized structures found between cardiac muscle fibers. They facilitate the transmission of electrical impulses and help synchronize the contraction of the heart muscle.

4. **Conclusion**:
- Based on the characteristics and definitions, intercalated discs are present in cardiac muscle tissue.

5. **Final Answer**:
- The correct answer to the question is: Intercalated discs are present in **cardiac muscle**.
