3 Anatomical Orientation

Zygoma (
Figs 3.15, 3.16)

The bony structures below the lateral orbit are formed by the

zygoma. 
S.I.-18is located directly below the outer canthus of

the eye at the lower border of the zygoma, at the junction of the

zygoma and the maxilla, on the anterior border of the masseter

muscle. (
Lower face and chin).

Zygomatic arch (
Figs 3.15, 3.16)

On the lateral aspect of the face, the temporal process of the

zygoma articulates with the zygomatic process of the temporal

bone to form the zygomatic arch. This is an approximately hori-

zontal bony structure which can be palpated laterally to the ear.


G.B.-3and 
T.B.-22are both located on the upper border of

the zygomatic arch, while 
ST-7and 
T.B.-21are situated at

its lower border.
