Study Notes

Bony Thorax Composition

The bony thorax consists of the sternum, 12 pairs of ribs, and 12 thoracic vertebrae.

Sternum Overview

Commonly known as the "breast bone," the proper term is sternum.
The sternum is classified as a flat bone.
It is composed of three parts: the manubrium, body, and xiphoid process.

Sterner Structure and Features

The manubrium is the most superior part of the sternum.
Clavicles articulate with the articular facets located just lateral to the jugular notch on the manubrium.
The sternal angle is formed by the junction of the manubrium and sternum body.
The body of the sternum serves as the elongated central portion.
The jugular notch is located at the superior border of the manubrium.
The xiphoid process is the smallest part of the sternum, located at the level of T10.

Rib Classifications

True ribs (1-7) attach their costal cartilages directly to the sternum.
False ribs (8-12) do not attach directly to the sternum, using hyaline cartilage instead.
Floating ribs (11 & 12) have no anterior attachments and do not articulate with the sternum.

Additional Sternum Details

The manubrium is the topmost part of the sternum and articulates with the clavicles, forming the sternoclavicular joint.
The landmark on top of the manubrium is known as the jugular notch.
The inferior portion of the manubrium connects with the body at the sternal angle.
The body of the sternum is also referred to as gladiolus and articulates with the true ribs and the xiphoid process.

Costal Cartilage

The costal cartilage connecting false ribs is made of hyaline cartilage.
Lower margins of the ribs sit at the vertebral levels of L2 and L3.
Ribs articulate with thoracic vertebrae.
