The Type of Cartilage That Forms the Costal Cartilages at the Ends

Question

The type of cartilage that forms the costal cartilages at the ends of the ribs is
A) hyaline cartilage.
B) fibrocartilage.
C) elastic cartilage.
D) calcified cartilage.

Accepted Answer

Hyaline cartilage is the most common type of cartilage and is found at the ends of bones in joints, at the tip of the nose, and in the trachea and bronchi. It is also the type of cartilage that forms the costal cartilages at the ends of the ribs. Fibrocartilage is found in areas that require additional support and elasticity, such as the intervertebral discs and the pubic symphysis. Elastic cartilage contains elastic fibers and is found in areas that require both support and flexibility, such as the external ear and the epiglottis. Calcified cartilage is a form of hyaline cartilage that has become calcified and is found in areas such as the growth plates of bones.
