A cervical rib in humans is an extra rib which arises from the seventh cervical vertebra. Their presence is a congenital abnormality located above the normal first rib. A cervical rib is estimated to occur in 0.2% [6] to 0.5% [7] (1 in 200 to 500) of the population. [8] People may have a cervical rib on the right, left or both sides. [9] [10]
This rudimentary rib causes fibrous changes around the brachial plexus nerves, inducing compression and causing the symptoms and signs of TOS. This is called a "cervical rib" because of its attachment to C-7 (the seventh cervical vertebra), and its surgical removal is almost always recommended. The symptoms of TOS can first appear in the early ...
Execution by hanging is intended to cause death from a cervical fracture. Considerable force is needed to cause a cervical fracture. Vehicle collisions and falls are common causes. A severe, sudden twist to the neck or a severe blow to the head or neck area can cause a cervical fracture.
Flail chest typically occurs when three or more adjacent ribs are fractured in two or more places, allowing that segment of the thoracic wall to displace and move independently of the rest of the chest wall. Flail chest can also occur when ribs are fractured proximally in conjunction with disarticulation of costal cartilages distally. For the ...

In tetrapods, cervical vertebrae (sg.: vertebra) are the vertebrae of the neck, immediately below the skull. Truncal vertebrae (divided into thoracic and lumbar vertebrae in mammals) lie caudal (toward the tail) of cervical vertebrae. [1] In sauropsid species, the cervical vertebrae bear cervical ribs.
In birds, ribs are present as distinct bones only on the thoracic region, although small fused ribs are present on the cervical vertebrae. The thoracic ribs of birds possess a wide projection to the rear; this uncinate process is an attachment for the shoulder muscles. [9] Usually dogs have 26 ribs. Mammals usually also only have distinct ribs ...
Rib fractures usually occur from a direct blow to the chest such as during a motor vehicle collision or from a crush injury. [2] [1] Coughing or metastatic cancer may also result in a broken rib. [1] The middle ribs are most commonly fractured. [5] [1] Fractures of the first or second ribs are more likely to be associated with complications. [6]
