Anatomy of Ribs
The number of the rib corresponds to
What is the thoracic vertebra it attaches to
This part of the rib articulates with the body of the thoracic vertebra
The first pair of sternocostal joints is functionally classified as
What is synarthrotic (immovable)
Classified as a flat bone, this provides attachment for the costal cartilage of the first seven pairs of ribs
What is the sternum
The centering points for ribs above and below the diaphragm
What is T-7 and T-10
The vertebral end of the rib is this much higher than the anterior end
This is located on the inferior and internal surface of the rib
What is the costal groove
The 6th-9th pair of interchondral joints are diarthrotic (gliding), where the 9th and 10th pairs are
What is amphiarthrotic, fibrous syndesmosis
This is formed by the junction of the manubrium and sternal body and lies at the level of the junction of the second costal cartilage
What is sternal angle (Angle of Louis)
For a lateral sternum, the height of the IR should be
What is 1.5 inches above the jugular notch
This rib is the narrowest
What is the 12th rib
This is the constricted portion of the rib just below the head
What is the neck
The costotransverse joints are functionally classified as
What is diarthrotic gliding
The manubriosternal joint is classified as
What is cartilaginous, symphysis, slightly movable (amphiarthrotic)
This demonstrates the axillary portion of the ribs on the side away from the IR, free of bony superimposition
What is the anterior obliques (RAO/LAO)
These ribs are also termed vertebrochondral ribs
What is pairs 8-10
This articulates with the transverse process to form the costotransverse joint
What is the costal tubercle
Costochondral joints are formed by
What is the junction of ribs and cartilage
In the upright position, the jugular notch lies anterior to the interspace between these vertebrae on the average person
What is between the second and third thoracic vertebrae
For AP ribs above the diaphragm, the IR is placed
What is 1.5 inches above the upper boarder of the relaxed shoulders
Ribs increase in length from ribs 1 through
What is 7
This is known as the axillary portion of the rib
What is the costal angle
These pairs of ribs form costochondral joints
The classification of the xiphisternal joint is
What is cartilaginous, synchondrosis, immovable (synarthrotic)
The central ray for RAO sternum enters
What is the elevated side of the posterior thorax at the level of T-7, 1 inch lateral to the MSP
