The upper and lower borders of the laminae are roughfor the attachment of the ligamenta subflava. The concavities aboveand below the pedicles are the intervertebral notches. The spinousprocess stands backwards from the angle of union of the laminae of thevertebra. It is the succession of these projecting processes along themiddle line of the back, that has given rise to the common designationof the vertebral column, the spine. The use of the spinous process isfor the attachment of muscles. The transverse processes T^io]&ci one ateach side from the laminaj of the vertebra; they also are intended for. CERVICAL VERTEBRAE. 11 the attachment of muscles. The articular processes, four in number,stand upwards and downwards from the lamiuse of the vertebra, toarticulate with the vertebra above and below. Cervical Vertebra.—In a cer-vical vertebra the body is smaller ^^S- ^*than in the other regions ; it isthicker before than behincl, broadfiom side to side, concave onthe upper surface, and convexbelow; so that, when articu-lated, the vertebrse lock the oneinto the other. The laminaare narrow and long, and theincluded spinal foramen largeand triangular. The superior in-tervertelral notches are slightlydeeper than the inferior; theinferior being the broadest. The spinous process is short and bifid at the extremity, increasing inlength from the fourth to the seventh. The transverse processes arealso short and bifid, and deeply grooved along the upper surface forthe cervical nerves. Piercing the base of the transverse process isthe verteb
