From C4–5, the thyroid cartilage [10] From C6–7, the cricoid cartilage [10] At C6, the oesophagus becomes continuous with the laryngopharynx and also where the larynx becomes continuous with the trachea. It is also the level where the carotid pulse can be palpated against the transverse process of the C6 vertebrae.
The target of C5 convertase is complement protein C5. C5 is a two-chain (α, β) plasma glycoprotein (Mr = 196,000). C5 and C3 have similar structure. However, C5 does not appear to contain the internal thiol ester group reported for C3 and C4. C5 has relatively few disulfide bonds.
The procedure involves cutting the lamina on both sides of the affected vertebrae (cutting through on one side and merely cutting a groove on the other) and then "swinging" the freed flap of bone open thus relieving the pressure on the spinal cord. The spinous process may be removed to allow the lamina bone flap to be swung open. The bone flap ...
GDF3 is involved with bone and cartilage growth. Mutations of GDF6, GDF3 and MEOX1 cause a reduced number of functional proteins that are coded by these genes, but it is unclear exactly how a shortage in these proteins leads to incomplete separation of the vertebrae in people with KFS. [ 10 ]
Cervicocranial syndrome can be caused either due to a defect (genetic mutation [9] or development of diseases later in life) or an injury pertaining to the cervical area of the neck that damages the spinal nerves traveling through the cervical region [10] [7] resulting in ventral subluxation. [11]

Cartilage is composed of a network of collagen type II held in tension by water-absorbing proteins, hydrophilic proteoglycans. [26] This is the adult skeleton in cartilaginous fishes such as sharks. It develops as the initial skeleton in more advanced classes of animals. In air-breathing vertebrates, cartilage is replaced by cellular bone.
Eburnation is a degenerative process of bone commonly found in patients with osteoarthritis or non-union of fractures. Friction in the joint causes the reactive conversion of the sub-chondral bone to an ivory-like surface at the site of the cartilage erosion. [1] The word derives from Latin eburneus, which means "of ivory". [2]
