Elastic cartilage is found in

Options

A. the auditory tube, larynx and pinnae of mammals
B. the trachea
C. spinal cord
D. intervertebral discs

Answer

**Step-by-Step Solution:**

1. **Understanding Elastic Cartilage**: Elastic cartilage is a type of connective tissue that is characterized by the presence of elastic fibers in its matrix. This allows it to provide both strength and flexibility.

2. **Identifying Locations of Elastic Cartilage**: Elastic cartilage is found in specific structures in the body. The key locations include:
- The external ear (also known as the pinna)
- The larynx (voice box)
- The auditory tube (also known as the Eustachian tube, which connects the middle ear to the throat)

3. **Function of Elastic Cartilage**: The primary function of elastic cartilage is to maintain the shape of these structures while allowing for moderate flexibility. This is crucial for the functioning of the ear and larynx, as they need to withstand various forces while maintaining their shape.

4. **Conclusion**: Based on the information, elastic cartilage is primarily found in the external ear (pinna), the larynx, and the auditory tube.

**Final Answer**: Elastic cartilage is found in the external ear (pinna), larynx, and auditory tube.
