Question

which type of connective tissue is found in the trachea and between the ribs and sternum?
○ dense regular connective tissue
○ hyaline cartilage
○ elastic cartilage
○ fibrous cartilage
○ areolar connective tissue

Explanation:

To solve this, we analyze each option:

• Dense regular connective tissue: Found in tendons/ligaments, not trachea or rib - sternum.
• Hyaline cartilage: It is the most common type of cartilage. It is found in the trachea (forming rings to support it) and at the costal cartilages (between ribs and sternum).
• Elastic cartilage: Found in structures like the ear and epiglottis, not in trachea or rib - sternum junctions.
• Fibrous cartilage: Found in intervertebral discs and pubic symphysis, not in the mentioned locations.
• Areolar connective tissue: A loose connective tissue, not the type found in trachea or rib - sternum.

Answer:

B. hyaline cartilage
