Book excerpt: Excerpt from Dublin Dissector, or Manual of Anatomy: Comprising a Description of the Bones, Muscles, Vessels, Nerves, and Viscera, Also the Relative Anatomy of the Different Regions, of the Human Body, Together With the Elements of Pathology The integuments covering the cranium are firm and dense, although when felt they give the sensation of being thin: the cuticle is delicate, but the cutis is very thick; the subjacent cellular membrane contains granulated fat, and the bulbs of the hairs, which afterwards perforate the skin in an oblique direction. The cellular tissue here has partly a ligamentous structure, and adheres so intimately to the subjacent muscular and tendinous, expansion, that the inexperienced student may find some difficulty in exposing the surface of the latter. Make an incision through the integuments along the median line, from the tuberosity of the occipital bone, as far forwards as the lower part of the forehead: from each extremity of this, make a transverse incision about three inches long; let the posterior one be parallel to the superior transverse ridge of the occipital bone, and the anterior one parallel, and about half an inch superior to the eyebrow; cautiously dissect off the integuments from the subjacent muscular and tendinous expansion, which is the occipito-frontalis. This muscle, like most of the superficial muscles of the face, is closely attached to the skin, which circumstance, added to the paleness and smallness of their fibres, renders their dissection somewhat difficult and tedious. Most of the superficial muscles of the head and face, during life, assist some of the organs of sense, and contribute to produce certain changes in the countenance, indicative of character or passion. The superficial muscles of the head are divided into those of the cranium and face. Those of the cranium are the occipito-frontalis, and the three common muscles of the ear. Occipito-Frontalis is the only muscle which properly belongs to the scalp; it is thin and broad, fleshy at each extremity, aponeurotic in the centre. It arises by tendinous and fleshy fibres on each side of the middle line, from the two external thirds of the superior transverse ridge of the occipital bone, and from the external and posterior part of the mastoid process; the fibres on each side ascend, from behind forwards, and from without inwards, and soon terminate in one thin and broad tendon, which extends over the upper and lateral parts of the cranium.
