08 Face, Neck, Integument, and Muscles Anatomy Flashcards
5 layers of epidermis from deep to superficial
- Stratum basale
- Spinosum
- Granulosum
- Lucidum
- Corneum
Dermis primarily contains what types of collagen
I - 80%
III - 15%
How does skin differ b/w asians and caucasians
Asians have thicker skin with greater collagen density and are more prone to hypertrophic scarring and prolonged erythema
How does the skin age differently b/w asians and caucasians
Asians develop fewer fine rhytids but more pigmented lesions than caucasians
What muscles draw the eyebrows medially and thus result in vertical glabellar rhytids
Corrugator supercilli
What is the relationship of the SMAS to the zygomatic arch
terminates 1 cm below the zygomatic arch
What is the relationship of the SMAS to the lower eyelid
It merges with the muscle fibers of the periorbital orbicularis oculi
What is the only location in the face where the SMAS is not covered by the fascial-fatty layer
superior portion of the lower eyelid
What is the relationship of the frontal branch of VII to the TPF
lies within it
What plane separates the TPF from teh deep temporal fascia
Subaponeurotic plane of loose areolar tissue
What separates the superficial and deep layers of the deep temporal fascia
superficial temporal fat pad
What fat pad separates the temporalis muscle from the deep temporal fascia and zygomatic arch
The deep temporal fat pad, an extension of buccal fat pad
What are the only mimetic muscles to receive innervation from VII on superficial surface
Buccinator
Levator anguli oris
Mentalis
Where are dense fibrous attachments b/w the superficial and deep facial fascias located
along zygomatic arch, overlying partoid, along anterior border of masseter
T/F: The buccal fat pad, parotid duct, facial art and vein, and FN all lie in same anatomic plane in cheek
true
