Thoracic Skeleton Flashcards
Articulation of the head of a rib with the inferior costal facet on one thoracic vertebra and the superior costal facet on the adjacent vertebrae.
Costovertebral joints
Articulation of the tubercle of a rib with the costal facet on the transverse process of a thoracic vertebrae.
Costotransverse joints
How many pairs of ribs does the human body have?
12 pairs
Form costovertebral joints by articulating with the costal demifacets of adjacent thoracic vertebral bodies and intervertebral discs.
Head of the rib
Articulates with the costal facets of the adjacent thoracic vertebral transverse processes.
Tubercle
Costal groove (on the shaft of the rib)
Houses the intercostal veins, arteris, and nerves.
Distal end of the rib shaft articulates with costal cartilage.
Costochondral joint.
Which ribs are true ribs?
1-7
Which ribs are false ribs?
8-10
Which ribs are floating ribs?
11 and 12
Consists of the manubrium, sternal angle, body and xiphoid process.
Sternum
A broad plate that has a notch on its superior border.
Manubrium
The clavicles articulate on the superior sides of manubrium, providing the only bony attachment between the upper limb to the axial skeleton.
Sternoclavicular joint
The junction between the manubrium and the sternal body.
Sternal angle (Angle of Louis)
Liamentum Arteriosum
Connects the pulmonary trunk to the aortic arch.
