Bones and Joints in the Thoracic Region The bones that create the architecture of the thoracic cage include the sternum, the ribs, and the thoracic vertebrae. The sternum: The sternum is a flat, long bone that forms the medial and anterior part of the thoracic cage. It has three parts: Manubrium: The manubrium forms the upper part of the sternum. It articulates with the clavicles and attaches to the cartilage of the first two ribs. Body: This part of the sternum articulates with the costal cartilages of the 2nd through 7th ribs on its sides and with the xiphoid process.

How Many Ribs Are Attached to the Sternum? How many pairs of ribs compose the thoracic cage? The thoracic cage, also known as rib cage, is composed of 12 pairs of ribs. It is comprised of bony and cartilagenous structures. It is surrounded by the thoracic cavity, and it supports the shoulder girdle.

Bones and Joints in the Thoracic Region The cartilaginous joints in your thoracic cage allow you to breathe. 1  The 1st ribs don’t move at all, but the act of breathing requires the other ribs to move up and down a bit, so the joints formed between the rest of the ribs and thoracic vertebrae allow for some movement: 1  Manubriosternal joint: The joint between the manubrium and the body of the sternum; forms the sternal angle.

PARTS OF THE SPINE The next 12 vertebrae make up the thoracic spine, running through the middle of the back and forming the back of the rib cage. It’s the least flexible part of the spine. Commonly the rib joint with the thoracic spine becomes stressed and can cause acute pain between the spine and shoulder blade. Other problems of this area would be hyperkyphosis, or humpback, and muscles tension. The thoracic spine can be associated with asthma and even some digestive problems.

Chapter 7 The adult sternum form the anterior midline of the thoracic wall and has 3 components. The manubrium is a broad triangular bone that articulates with the clavicles and the cartilage of the first pair of ribs. The body attaches to the inferior surface of the manubrium and articulates with the cartilage of ribs 2-7.

Related category The body of the sternum articulates above with the manubrium by means of a fibrocartilaginous joint (a symphis) called the manubriosternal joint, which allows slight movement between these two parts of the sternum when the ribs rise and fall during breathing.

AnatomyThe ribs and intercostal spaces Abstract. Of the 12 ribs, the first 7 are ‘true’ and articulate via their costal cartilages with the sternum; ribs 8 to 10 articulate with each other through their costal cartilages (false ribs), while ribs 11 and 12 have costal cartilages that end in the abdominal wall muscles (floating).f the 12 pairs of ribs, pairs 1–7 are connected by their costal cartilages to the sternum (true ribs), the cartilages of ribs 8, 9 and 10 articulate with each other (false ribs), and pairs 11 and 12 are free anteriorly, capped by costal cartilage (floating ribs).

- The thoracic vertebrae are a group of twelve small bones that form the vertebral spine in the upper trunk. Thoracic vertebrae are unique among the bones of the spine in that they are the only vertebrae that support ribs and have overlapping spinous processes.

A Patient's Guide to Low Back Pain (overview) The thoracic spine is made up of the middle 12 vertebrae. These vertebrae connect to your ribs and form part of the back wall of the thorax (the ribcage area between the neck and the diaphragm). The thoracic spine's curve is kyphotic, a C-shaped curve with the opening of the C in the front.

thorax The principal organs in the thoracic cavity are the heart with its major blood vessels and the lungs with the bronchi, which bring in the body's air supply. The trachea enters the thorax to connect with the lungs, and the esophagus travels through it to connect with the stomach below the diaphragm.

The Muscles of the Thoracic Cage The Muscles of the Thoracic Cage. There are five muscles that make up the thoracic cage; the intercostals (external, internal and innermost), subcostals, and transversus thoracis. These muscles act to change the volume of the thoracic cavity during respiration. There are some other muscles that do not comprise the thoracic wall, but do attach to it.

RIB CAGE ANATOMY The second through the tenth ribs meet with the body of the sternum via costal cartilage. The xiphoid process is available for muscle attachment and does not adhere to the ribs. The costal margin of the ribcage is formed by the fusion of the eight, ninth, and tenth ribs’ coastal cartilage.

Unit  IV â The Thoracic Cage/ Respiration & Breathing It is formed by the 12 pairs of ribs, the sternum (breast bone), costal cartilages, and the 12 thoracic vertebrae. These bony and cartilagenous structures form the thoracic cage (rib cage) which surrounds the thoracic cavity and supports the shoulder girdle.

How many pairs of ribs are there what type of Rib 1 and ribs 10-12 articulate with only one vertebral body, and ribs 11 and 12 do not articulate with a vertebral transverse process. Answer “check your understanding” question 17 on page 180. Define the sternal angle. Which rib articulates with the sternum at this landmark? The sternal angle is the junction between the manubrium and the body of the sternum. Rib 2 articulates here.
