I just heard of this condition where there is an extra bone growing out of a person's neck. I guess you can't see it and it is genetic... any idea what it is or how it is passed? Thanks!
Extra rib?

Maybe you're referring to the thoracic outlet syndrome??? An anomalous cervical rib compresses the lower trunk of the brachial plexus --> paralysis of ulnar and median nerves, compresses subclavian aa --> diminished radial pulse when turn head to opposite side. See p 111 of first aid..

Yeah, you can have a cervical rib bilaterally. This rib arises from C7 (the last cervical vertebrae) and can compress structurs like the subclavian artery and the brachial plexus leading to both vascular and neurological problems with the upper extremities.
Kind of cool to see on x-ray though..

Actually I just learn about this condition yesterday while studying the Thoracic region. There is such a condition in which a person can have an extra lumbar rib. It's a thriteenth rib more or less among the floating ribs. It is not present in every human. It is more common than Cervical rib and normally goes undetected. The condition is known as Anomalous therteenth rib (lumbar "gorilla" ribs) and arises from the lumbar vertebra L1. A lumbar rib is an abnormality of costal development resulting in the formation of a rib or ribs that articulate with: the first lumbar vertebra or the tip of the transverse process of the first lumbar vertebra Relatively more common than cervical rib, it is clinically important because: on lumbar radiogram, it may be misinterpreted as a fracture of the L1 transverse process it may confuse the appreciation of target organs during surgery
However, clinically it is usually silent. One most not confuse this condition with Cervical rib which arises from the transverse process of vertebra C7 (also known as thoracic outlet syndrome) which is less common than the thirteenth rib.
You may go here for reference to this condition gpnotebook
Also if you have a copy of the NMS (National Medical series for Independent study- Clinical Anatomy), on page 246 you'll find a brief mention of it.
Hopes this helps
