Question

Sternum is connected to ribs by

• A. bony matter
• B. white fibrous cartilage
• C. hyaline cartilage
• D. areolar tissue

Answer 1

The Correct Option is C

The sternum (also known as the breastbone) is connected to the ribs by hyaline cartilage.

Hyaline cartilage is a type of flexible connective tissue that provides support and allows for slight movement between bones. In the case of the sternum and ribs, the hyaline cartilage forms the costal cartilages, which connect the ribs to the sternum. These costal cartilages allow for some flexibility and movement during activities such as breathing.

The hyaline cartilage is responsible for connecting the sternum and ribs, providing structural integrity, and allowing for some degree of movement in the ribcage.

Answer 2

The ribs and the sternum are joined by a cartilaginous juncture. Cartilaginous joints, commonly known as symphysis or synchondrosis joints, are partly movable joints. These joints can only be found in areas where the articulating bone connections are made of cartilage. Synchondrosis is a condition in which young children have temporary cartilaginous joints that last into puberty. Cartilaginous joints are entirely composed of cartilage. Cartilaginous joints are more flexible than fibrous joints, allowing for more bone motion. The costal cartilage links the rib to the sternum and is positioned between the ribs and the sternum.
