T3 - T4
What ligament joins the ribs and the vertebral bodies?
Costotransverse bodies
What kind of joint is the intervertebral joint?
Symphysis (secondary cartilaginous joint)
What kind of joint is the costovertebral joints of the head of the ribs?
Synovial plane
What kind of joint is the costotransverse joint?
Synovial plane
What kind of joint is the 1st sternocostal joint ?
Primary cartilaginous joint

What type of joint is the sternoclavicular joint?
Saddle
What type of joint is the costochrondral joint?
Primary cartilaginous
What kind of joint is the interchondral joint?

Where is the weakest part of the rib?
Just anteriorly to its angle
What is flail chest?
A sizeable segment of the anterior and/or lateral thoracic wall moves freely because of of multiple rib fractures
What can a cervical rib cause and where is it normally found?
It articulates with the C7 vertebra and can compress spinal nerves C8 to T1 or the inferior trunk of brachial plexus supplying upper limb. They can also compress subclavian artery.
What can compression of spinale nerves C8 - T1 cause?
Tingling and and numbness may occur along the medial border of the forearm.
What can compression of subclavian artery cause?
Ischemic muscle pain which is caused by poor blood supply.
What is thoracotomy?
Surgical creation of an opening through the thoracic wall to enter a pleural cavity.
What is anterior thoracotomy?
It involves making H-shaped cuts through the perichondrium of one or more costal cartilages and then shelling out segments of costal cartilage to gain entrance to the thoracic cavity.
How does the breast lymph drain to the central and apical axillary nodes?
Via Infraclavicular and pectoral nodes
Where do the internal thoracic arteries arise from?
Subclavian artery
Where do the intercostal arteries supply?
The 1st six intercostal spaces
