Surgical anatomy : a treatise on human anatomy in its application to the practice of medicine and surgery . —The collateral circulation is established by theanastomosis of the vertebral arteries and opposite internal carotid with the liga-tured artery through the circle of Willis. Irregularities.—The irregularities of the internal carotid artery which areof importance are the following: It may arise from the arch of the aorta or theinnominate artery ; its cervical portion may be tortuous ; it may give origin to theoccipital artery. OPERATIONS UPON NERVES OF HEAD AND NECK. The supra-orbital nerve is exposed at the supra-orbital notch or foramen,which is located at the junction of the middle one-third with the inner one-thirdof the supra-orbital margin. The eyelid is drawn downward and the eyebrowheld steady while a transverse incision is made along the supra-orbital incision is one-half to three-fourths of an inch in length and divides skin,superficial fascia, and orbicularis palpebrarum muscle. The nerve is now PLATE CXGV, Orbicularis palpebrarum mPeriosteumSuperficial fascia. Supraorbital fascia
