The sternum is bone.
The sternum is lined by a type of connective tissue called hyaline cartilage. This cartilage provides a smooth surface for the articulation of the ribs and contributes to the flexibility and strength of the rib cage. Hyaline cartilage is also found in other areas of the body, such as the joints and the respiratory tract, where it serves similar functions.
Hyaline Cartilage
"Retrosternal" means behind the sternum (breastbone), while "fat pad" refers to a localized accumulation of fat tissue. Therefore, a retrosternal fat pad is a collection of fat located behind the sternum in the chest area.
The mass of tissue from the sternum to the vertebral column is the pectoral muscle, specifically the pectoralis major muscle. It is a large muscle that covers the chest area and is responsible for movements like flexing and rotating the arm.
The type of connective tissue found in the trachea and between the ribs and sternum is hyaline cartilage. Hyaline cartilage is a smooth and flexible type of connective tissue that provides support and reduces friction between bones.
Transitional tissue is a type of epithelial tissue.
