The muscle between 25 and 26 is the ORBITAL GROUP. 187 the mastoid portion of the temporal bone. Its insertion takes placeby means of the blending of the fibres of its anterior portion withthose of the orbicularis palpebrarum, corrugator supercilii, levatorlabii superioris aloeque nasi, and pyramidahs nasi. The muscle isfleshy in front over the frontal bone and behind over the occipital, thetwo portions being connected by a broad aponeurosis. The twomuscles together with their aponeurosis cover the whole of the vertexof the skull, hence their designation galea capitis; they are looselyadherent to the pericranium, but very closely to the integument, par-ticularly over the forehead. Relations.—This muscle is in relation by its external surface frombefore backwards, with the frontal and supra-orbital vessels, the supra-orbital and facial nerve, the temporal vessels and nerve, the occipitalvessels and nerves, and with the integument, to which it is veryclosely adherent.
