To define the central sulcus (fissure of Rolando) two points are taken; one is situated 1.25 cm. behind the center of the line joining the nasion and inion; the second is at the intersection of the line of the posterior ramus of the lateral cerebral fissure with a line through the preauricular point at right angles to Reid’s base line.

The anterior auricular glands (lymphoglandulæ auriculares anteriores; superficial parotid or preauricular glands), from one to three in number, lie immediately in front of the tragus.

An alternative method is to draw two perpendicular lines from Reid’s base line to the top of the head; one from the preauricular point and the other from the posterior border of the mastoid process at its root.

—The anterior sacroiliac ligament consists of numerous thin bands, which connect the anterior surface of the lateral part of the sacrum to the margin of the auricular surface of the ilium and to the preauricular sulcus.
