What is the most inferior rib?

There are two pairs of floating ribs and they are the most inferior of the ribs. They are different from the other ribs of the thoracic region because they do not articulate anteriorly with the sternum or the costal cartilage of other ribs.

What is the correct order of the ribs and how many of each type of rib do you have?

There are three types of ribs:

Seven ribs which connect directly to the sternum (1-7) Three ribs which connect to the costal cartilages of the rib above (8-10) Two "floating" ribs which connect only at the back (11&12)

What are the 3 groups of ribs?

According to their attachment to the sternum, the ribs are classified into 3 groups: true, false, and floating ribs. The false ribs (8,9,10) are the ribs that indirectly articulate with the sternum, as their costal cartilages connect with the seventh costal cartilag by the costochondral joint.

What are the three regions of the sternum listed from most superior to most inferior?

The sternum is a partially T-shaped vertical bone that forms the anterior portion of the chest wall centrally. The sternum is divided anatomically into three segments: manubrium, body, and xiphoid process. The sternum connects the ribs via the costal cartilages forming the anterior rib cage.

What is the correct order for the vertebral regions from superior to inferior?

From superior to inferior, these are: Cervical: 7 vertebrae (C1 = highest; C7 = lowest) Thoracic: 12 vertebrae (T1 = highest; T12 = lowest) Lumbar: 5 vertebrae (L1 = highest; L5 = lowest)

What is superior to the rib cage?

Sternum. The sternum is the elongated bony structure that anchors the anterior thoracic cage. It consists of three parts: the manubrium, body, and xiphoid process. The manubrium is the wider, superior portion of the sternum.

Where is rib 7 and 8 located?

Ribs 1–7 are classified as true ribs (vertebrosternal ribs). The costal cartilage from each of these ribs attaches directly to the sternum. Ribs 8–12 are called false ribs (vertebrochondral ribs). The costal cartilages from these ribs do not attach directly to the sternum.

How are the ribs numbered?

All ribs are attached posteriorly to the thoracic vertebrae. They are numbered to match the vertebrae they attach to – one to twelve, from top (T1) to bottom. The head of the rib is the end part closest to the vertebra with which it articulates.

Where are the 8th 9th and 10th ribs located?

These ribs, known as true ribs, also connect to your spine in the back. The 8th, 9th, and 10th rib pairs don't connect directly to your sternum, but they are connected to each other by cartilage that attaches to the costal cartilage of the 7th rib pair. These ribs also attach to your spine in the back.

What is first rib?

The first rib is the most tightly curved of all the ribs. It's also the broadest of the ribs. ... The costal cartilage of the first rib articulates with the manubrium of the sternum not at the top, but lower down at its broadest part. The first costal cartilage is short and massive.

What are the parts of a rib?

The parts of a rib include the head, neck, body (or shaft), tubercle, and angle. The head of the rib lies next to a vertebra. The ribs connect to the vertebrae with two costovertebral joints, one on the head and one on the neck.

What attaches to the first rib?

The first rib has several attachments which are listed below; Anterior scalene muscle: scalene tubercle. Middle scalene muscle: between groove for the subclavian artery and transverse tubercle. Intercostal muscles: from the outer border.

Which part of the sternum is most superior portion and site of articulation with the first and second costal cartilages?

The manubrium forms the expanded, superior end of the sternum. It has a jugular (suprasternal) notch, a pair of clavicular notches for articulation with the clavicles, and receives the costal cartilage of the first rib.

Which ribs connect directly to the sternum?

The first seven pairs are attached directly to the sternum by costal cartilages and are called true ribs. The 8th, 9th, and 10th pairs—false ribs—do not join the sternum directly but are connected to the 7th rib by cartilage.
