from S nuchal lines of O bone to supraorbital ridge of F bone



S ==> skin
C ==> connective tissue containing neurovasculature
A ==> aponeurosis of occipitofrontalis, tempoparietalis, and S auricular muscles
L ==> loose areolar tissue
P ==> periosteum


What lie in the loose connective tissue layer?

muscles of facial expression
- originate on bones of face
- insert into overlying skin


From what a. are the branches that supply the face and scalp?

EXTERNAL carotid a.
- S and I labial aa. --> lips
- L nasal a.
- angular branches of facial a.
- mental branch of I alveolar a. --> chin
- superficial temporal a.
- P auricular a.
- occipital a.
- supratrochlear and supraorbital branches of ophthalmic a. (branch of INTERNAL) ==> anastomose w/ angular a.


sensory nn. of face and scalp

supraorbital and supratrochlear nn. (CN V1)
infraorbital n. and zygomaticotemporal and zygomaticofacial n. (V2)
auriculotemporal n., buccal n., and mental n. (branch of I alveolar n.) (V3)
great auricular n. and lesser occipital n. --> A rami of C2 and C3 via C plexus
greater occipital n. and 3rd occipital n. --> P rami of C2 and C3


motor nn. of face and scalp

temporal, zygomatic, buccal, and marginal mandibular branches of facial n. (CN VII) ==> facial muscles
T and P auricular branches of facial n. ==> scalp muscles
muscular branches of mandibular division of trigeminal n. (CN V3) ==> muscles of mastication
