The intercostal space (ICS) is the anatomic space between two ribs (Lat. costa). Since there are 12 ribs on each side, there are 11 intercostal spaces, each numbered for the rib superior to it. Since there are 12 ribs on each side, there are 11 intercostal spaces, each numbered for the rib superior to it.
The parts of the rib. Each rib consists of a head, neck, and a shaft. 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. It is marked by a kidney ...
Anatomical terms of bone [ edit on Wikidata ] The suprasternal notch , also known as the fossa jugularis sternalis , jugular notch , or Plender gap , is a large, visible dip in between the neck in humans, between the clavicles , and above the manubrium of the sternum .
[2]: 321 Counting ribs is essential attempting to make a thoracic incision; an incision at the first or second rib interspace can result in damage to large, important blood vessels and the brachial plexus. Identification of the second rib and thus the second intercostal space inferiorly is useful when auscultating heart sounds.
In cardiology, Erb's point refers to the third intercostal space on the left sternal border where S2 heart sound is best auscultated. [5] [6] Some sources include the fourth left interspace. [7] Human female breasts are located on the chest wall, most frequently between the second and sixth rib. [4]
Passing backward, it splits into the deep cervical artery and the supreme intercostal artery (highest intercostal artery), which descends behind the pleura in front of the necks of the first and second ribs, and anastomoses with the first aortic intercostal (3rd posterior intercostal artery). As it crosses the neck of the first rib it lies ...
The internal intercostal muscles (intercostales interni) are a group of skeletal muscles located between the ribs.They are eleven in number on either side. They commence anteriorly at the sternum, in the intercostal spaces between the cartilages of the true ribs, and at the anterior extremities of the cartilages of the false ribs, and extend backward as far as the angles of the ribs, hence ...
The costovertebral joints are the joints that connect the ribs to the vertebral column. The articulation of the head of rib connects the head of the rib and the bodies of vertebrae. The costotransverse joint connects the rib with the transverse processes of vertebrae.
