Nov 18, 2022 · The ribs are 12 pairs of curved, flat bones that form the thoracic cage or rib cage, the bony structure that shapes the thoracic cavity and protects various organs. Despite being relatively thin and light, these bones are highly resilient.

The part of the ribs that articulates with the thoracic vertebrae (in your spine) is called the proximal end and the part that articulates with the costal-cartilage / sternum (in the centre of your chest) is called the distal end.

Aug 16, 2023 · There are three parts to each rib: the head, the neck, and the shaft, or body, of the rib. The head of your ribs are shaped like a wedge and have two specific areas called facets. These facets articulate with your spinal vertebrae.

4 days ago · As part of the bony thorax, the ribs protect the internal thoracic organs. They also have a role in ventilation; moving during chest expansion to enable lung inflation. In this article, we shall look at the anatomy of the ribs – their bony landmarks, articulations and clinical correlations.

Nov 2, 2022 · Review the anatomical characteristics of the rib and ribcage in this interactive tutorial and test your knowledge in the quiz.

In this anatomy lesson, I’m going to cover the rib bones, also called costae in Latin. The ribs help protect vital organs in the thorax such as the heart and lungs, and they assist with breathing. Don’t be fooled their long, curved shape! Rib bones are not classified as long bones.

Oct 30, 2023 · The next group of fibres are known as the lateral costotransverse ligament, which lies posteriorly and attaches the transverse process of the vertebra to the rib, just distal to the tubercle. The final part is the superior costotransverse ligament which is a two-layered ligament with the fibres orientated at right angles.

The rib cage protects the two major organs in the thoracic cavity, the heart and the lungs. Supports the upper body, keeping it stable. It provides a point of attachment for the clavicles, thus establishing the connection between the arm and the axial skeleton.

Jan 3, 2019 · Ribs are numbered from the first to the twelfth starting with the most superior rib. The distal end of each ribs has a cartilaginous extension known as a costal cartilage. Ribs 1-7 are known as the sternal ribs because the costal cartilages connect directly to the sternum.

Jul 10, 2023 · However, the floating ribs are the ribs that do not articulate with the sternum at all; they are the distal two ribs. The true ribs articulate with the sternum by the sternocostal joints. The first rib is an exception to that rule; it is a synarthrosis.
