The dissector's guide, or, Student's companion : illustrated by numerous woodcuts, clearly exhibiting and explaining the dissection of every part of the human body . vertebrae, descending obliquely, to beinserted into the whole length of the base of the scapula, below itsspine. Action, — to draw the scapula upwards and backwards. e. The serratus posticus inferior arises from the two inferior dorsal,and from the three lumbar vertebra?, by means of the fascia lumborum,to be inserted, by four fleshy slips, into the same number of inferiorribs, near their cartilages. Action, — to depress the ribs into which it isinserted, and thereby, during expiration, to assist in contracting the cav-ity of the thorax. /. The levator scapula? arises from the transverse processes of the fivesuperior cervical vertebra?, by the same number of distinct heads, whichsoon unite to form a flat muscle, running downwards and outwaids, tobe inserted into the superior angle of the scapula. Action, — to pull thescapula upwards and a little forwards, as in shrugging the shoulder; andwhen the scapula is fixed, to pull the neck a little to one side. THE DISSECTORS GUIDE. 177. These muscles may be reflected, when the following willbe brought into view. g. The serratus posticus su-perior. h. The splenius capitis. i. The splenius colli. k. The spinalis dorsi. I. The longissimus dorsi. m. The sacro-lumbalis. n. The complexus. o. The cervicalis descen-dens. f. The transversalis The trachelo-mastoideus. g. The serratus posticus su-perior arises by a broad thintendon, from the ligamentumnuchas, over the spinous pro-cesses of the three last cervi-cal, and two uppermost dor-sal vertebras ; going obliquelydownwards, to be inserted, byfour fleshy slips, into the sec-ond, third, fourth, and fifthribs, under the upper and backpart of the scapula. Action,-thorax in violent inspiration. h. The splenius capitis arises tendinous, from the two superior spi-nous processes of the dorsal, and tendinous and
