Body's framework of bones, cartilage and connective tissues?

• A. Skeletal System
• B. Onychia
• C. Pediculosis
• D. Petechiae

Answer: (A)

The skeletal system is the body's framework of bones, cartilage, and connective tissues. It provides structure and shape, supports soft tissues, protects vital organs, and enables movement in collaboration with muscles through joints. Bones store minerals and house bone marrow for blood cell production, while cartilage cushions joints and allows smooth movement. Ligaments and other connective tissues help stabilize and connect the components of the framework.

Onychia refers to inflammation of the nail bed, which is a nail condition and not about the body’s framework. Pediculosis is an infestation with lice, a skin/parasite condition. Petechiae are tiny red or purple spots from small blood vessel bleeding under the skin, not a structural system term. Therefore, the term that matches the description is the skeletal system.
