If connective tissue layers extend beyond muscle, like a chord or sheet they are called respectively  

Options

A. tendon & ligament
B. ligament & tendon
C. tendon & sarcomere
D. tendon & aponeurosis

Answer

To answer the question regarding the connective tissue layers that extend beyond muscle, we can break down the solution step by step:

### Step-by-Step Solution:

1. **Understanding Connective Tissue**:
- Connective tissue is a type of tissue that supports, protects, and gives structure to other tissues and organs in the body. Examples include bone, cartilage, fat, and blood.

**Hint**: Remember that connective tissues have various forms and functions in the body.

2. **Identifying Tendons**:
- A tendon is a fibrous connective tissue that connects muscle to bone. It is typically cord-like in structure and is made up of collagen fibers.

**Hint**: Think of tendons as the "ropes" that attach muscles to bones.

3. **Identifying Ligaments**:
- A ligament is also a fibrous connective tissue, but it connects bone to bone. It helps stabilize joints and maintain structural integrity.

**Hint**: Ligaments are more like "bands" that hold bones together rather than connecting muscles.

4. **Understanding Aponeurosis**:
- Aponeurosis is a type of connective tissue that is flat and sheet-like. It serves as an attachment point for muscles to connect to bones and also helps bind muscles together.

**Hint**: Visualize aponeurosis as a "sheet" that covers and connects muscles.

5. **Evaluating the Options**:
- The options provided are:
- Tendon and ligament
- Ligament and tendon
- Tendon and sarcomere
- Tendon and aponeurosis

- From our analysis:
- Tendon is correct as it is cord-like.
- Ligament is not correct as it is not sheet-like.
- Sarcomere is part of muscle tissue, not connective tissue, so it is incorrect.
- Aponeurosis is correct as it is sheet-like.

6. **Conclusion**:
- The correct answer is "Tendon and Aponeurosis" because tendons are cord-like structures that connect muscles to bones, while aponeurosis is a sheet-like structure that connects muscles to bones and binds muscles together.

**Final Answer**: Tendon and Aponeurosis.
