The C-Shaped Rings That Provide Support for the Wall of the Trachea

Question

The C-shaped rings that provide support for the wall of the trachea are made out of
A)hyaline cartilage
B)elastic cartilage
C)fibrocartilage
D)reticular connective tissue
E)bone

Accepted Answer

The rings are made of hyaline cartilage, which is a smooth, flexible connective tissue that maintains the shape of the trachea while allowing it to move during breathing. Elastic cartilage is similar to hyaline cartilage, but can stretch and recoil. Fibrocartilage is found in areas that require extra support and strength, such as the intervertebral discs in the spine. Reticular connective tissue forms supportive networks, but is not typically found in the trachea. Bone is a hard, rigid tissue that is not present in the trachea.
