Which type of connective tissue cushions the ends of bones at their joints?

• A. Dense regular connective tissue
• B. Adipose tissue
• C. Areolar connective tissue
• D. Hyaline cartilage

Answer: (D)

Verified step by step guidance

1. Understand the role of connective tissues: Connective tissues provide support, structure, and protection to the body. Different types of connective tissues have specialized functions, such as cushioning, energy storage, or structural support.
2. Review the function of hyaline cartilage: Hyaline cartilage is a type of connective tissue that is smooth and resilient. It is specifically designed to reduce friction and absorb shock at joints, making it ideal for cushioning the ends of bones.
3. Compare the other options: Dense regular connective tissue primarily provides tensile strength and is found in tendons and ligaments. Adipose tissue stores energy and provides insulation. Areolar connective tissue is a loose connective tissue that supports and binds other tissues but does not cushion joints.
4. Identify the correct answer: Based on the function of hyaline cartilage and the roles of the other connective tissues, hyaline cartilage is the correct type of connective tissue that cushions the ends of bones at their joints.
5. Conclude: Hyaline cartilage is essential for smooth joint movement and preventing bone-to-bone contact, which could lead to damage or pain.
