h) Supraorbital margin.
i) Supraorbital notch (or foramen) (for the passage of the supraorbital artery, vein and nerve).
k) Frontal bone, nasal process.
l) Nasal Spine.
m) Nasal process of the maxilla (origin of mm frontalis, orbicularis palpebrum, and levator labii superioris alaeque nasi, and zygomaticomaxillary suture and medial palpebral ligament).
n) Zygomatic process of the maxilla.
o) Alveolar process of the maxilla (origin of mm. compressor, depressor nasi, buccinator,and incisivi labii superioris and inferioris).
p) Infraorbital foramen (exit of infraorbital canal carrying the infraorbital artery, vein, and nerve).
q) Maxillary depression (origin of m. levator anguli oris).

u) Fossa of the lacrimal sac.
v) Alveolar yokes.
w) Maxillary process of the zygomatic bone (origin of m. zygomaticus minor).
x) Frontal of the zygomatic bone.
y) Temporal process of the zygomatic bone.
z) Zygomaticofacial foramen. (transmits the zygomaticofacial nerve).

a)Mentum (chin), external mental spine.
b) Mental foramen (exit for the mental artery, vein, and nerve).
g) Mandibular angle (beginning of mm masseter and medial pterygoid).
d) Mandibular ramus.
e) Mastoid process.
z)Optic foramen (for the optic nerve and ophthalmic artery).
h) Superior orbital fissure. (between the greater and lesser wings of the sphenoid bone) (passage for the ophthalmic vein, nn. oculomotor, trochlear, ophthalmic, and abducens nerves).
q) Inferior orbital fissure (between the greater wing of the sphenoid and maxillary bone) (passage for ophthalmic vein, infraorbital nerve, artery, and vein, and cutaneous nerve of the cheek).
