Face - Anterior View
-
Platysma muscle - arising from skin and inferior border of mandible, extending
inferiorly to level of second rib
-
Supraorbital n.a.- lateral to trochlea for superior opbique, extending
superiorly along superficial aspect of frontalis
-
Supratrochlear n.a. - superior to trochlea for superior oblique, distributing
to angle between orbit and naison
-
Infratrochlear n.a. - inferior to trochlea for superior oblique, distributing
to angle between orbit and nose
-
Infraorbital n.a. - posterior (deep) to levator labii superiorus
-
Lacrimal n. - piercing orbital septum in upper lateral quandrant (not easily
seen)
-
Orbital septum - continuous with periosteum of orbital rim
-
Lateral palpebral lig. - attaching superior and inferior tarsal plates
to orbital rim
-
Medial palbebral lig. - attaching superior and inferior tarsal plates to
orbital rim
-
Lacrimal sac - posterior inferior and posterior superior to medial palprebral
lig.
-
Mental n. - posterior to mentalis and 3 cm lateral to midline
-
Superior and inferior labial arteries - branches of facial a. near lateral
aspect of upper and lower lip
-
Angular a. - extension of facial a. near angle of nose
-
External nose - nasal cartilages (septum, alar)
Face - Lateral View
-
Parotid duct - crossing lateral surface of masseter, entering buccinator
muscle near upper 2nd molar
-
Facial nerve - visible passing through substance of parotid gland
-
temporal branch - crossing temporal bone (squamous part) anterior to ear
-
zygomatic branch - crossing zygomatic arch, coursing toward obicularis
occuli
-
buccal branch - crossing masseter and providing motor supply to buccinator,
passing through buccal fat pad
-
mandibular branch - crossing mandible toward obicularis oris
-
cervical branch - crossing mandible to provide motor to platysma
-
Buccal nerve - crossing medial (deep) to masseter through buccal fat pad,
deep branch pierces buccinator to provide sensory to oral mucosa
-
Buccal branch of facial n. - crossing lateral to masseter to supply SVE
to buccinator m.
-
Buccal n. - crossing medial to masseter to supply GSA to mucosa and skin
of buccal region (V3)
-
Facial a. - crossing body of mandible anterior to masseter m., passing
through submandibular gland
-
Inferior labial a. - branching from facial
-
Superior labial a. - branching from facial (possible common trunk for inferior
and superior labial arteries)
-
Facial vein - paralleling course of facial artery, posterior to facial
artery
-
External ear
-
Helix
-
Antihelix
-
