Difference between typical cervical & thoracic veebra
High-Yield Explanation
CERVICAL VEEBRAE They are identified by the presence of foramen transversaria.There are seven cervical veebrae,out of which the third to sixth are typical,while the first,second and seventh are atypical. Typical cervical veebra Body 1.The body is small and broader from side to side than from before backwards. 2.The superior surface is concave transversely with upward projecting lips on each side. 3.The inferior surface is saddle shaped,being convex from side to side and concave from before backwards. 4.The anterior and posterior surfaces resemble that of other veebrae. Veebral Foramen It is larger than the body.It is triangular in shape because the pedicles are directed backwards and laterally. Veebral Arch 1.The pedicles are directed backwards and laterally. 2.The laminae are relatively long and narrow,being thinner above than below. 3.The superior and inferior aicular processes form aicular pillars which project laterally at the junction of pedicle and the lamina. 4.The transverse processes are pierced by foramina transversaria.
