The Best Cheat Sheet
· _________________________________ and feel each of the following locations/features on your face and cranium while discussing and studying.
· This will help you better understand what the text is speaking of regarding ___________________________________________ (thickness/thinness).
· Doing this will help you on your exams—because YOU ARE YOUR BEST CHEAT SHEET!!! Commit these to memory as you study using yourself as a guide. YOU are the one thing you can have with you when taking your exams/comps, so let yourself be study material to help absorb this information.

Mouth

Cheek (AKA: _____________________________)
· Contains a considerable ______________________________
· Superficial fascia is tougher and more fibrous than at other parts
· Between the ______________________________________________:
· Muscles, fat, areolar tissue, blood vessels, nerves, and glands are found
· Fascia covering the cheekbone _____________________________
· A greater amount of fat is found on the part of the
_______________________________________________________
· _______________________________
· Contributes to the fullness of the _____________________________________ between the angle of the jaw and the Zygomatic Arch
· Posterior border of the muscle is covered by part of the ________________________ which extends to the ear
· Fullness of the anterior cheek is produced by facial muscles and __________________________________________
· Encapsulated mass of fat lying _________________ to the Masseter Muscle but ________________________ to its front border
Chin
· __________________________ of the chin is covered by tissues which are somewhat dense
· Composed of _______________________ and moderately
________________________________________________
· Only at the __________________________________ of the bone is the tissue close to
the body structure
Submandibular Area
· Superficial fascia of the region, ______________________________, is thinner and less dense than the fascia of the facial area
· May contain very little or develop a moderately large amount of adipose tissue
· Fascia splits to enclose the __________________________________
· Two layers come together again for a short distance near the _________________ and then separate again to ensheath (cover) the Parotid Gland
Integument (aka: _________________)
· Face is covered by skin that is thin, highly vascular, and supplied with many
______________________________________________________________________
· Consists of a layer of dense connective tissue (AKA: ____________or ______________) and an external covering of epithelium (Epidermis)
· _____________________________________________________________
· ___________________________ but also, an agent of water output
· Has absorbing powers; it will absorb oily materials placed in contact with it
· Thickness of skin varies between one-thirty second (1/32) to a little more than one-sixteenth (1/16th) of an inch
· ____________________________________________
· Ability of the skin to be stretched varies with its thickness
· Density of the __________________________________ and the firmness of fixation by the superficial fascia are directly related to its mobility
· ______________________________________________________________
· Texture _____________________________________________ and at various ages
Starts soft and as time passes, many things affect the texture of the skin
Derma (AKA _______________________________)
· The deeper layer of the skin
· ______________________________________________________________________
· Thickness varies in different parts of the body
· Consists of _______________________________________________
· Contains a small amount of fat, rich plexuses of blood vessels and lymphatics, nerve twigs, and numerous sensory nerve endings
· Moving down the _____________________________________________________ are hair follicles, sebaceous glands, the ducts of sweat glands, and bundles of smooth muscle fibers
· Deeper layer of Derma is a mass of ________________________________________________________________________
________________________________________________________________________
· This layer is mostly responsible for the ______________________________
· Sebaceous glands are _____________________ found in most parts of the skin
· Are especially abundant in the ______________________________
Epidermis
· Remember: ______________________________________________
· So, over, or on, the dermis
· _________________________________________________
· Has no __________________________________________
· Composed if four strata (layers) of cells
· Three outer layers are practically dead and constantly shed to be replaced by new ones from the fourth layer
· _______________________________________________
· Protoplasm of cells has become chemically changed into a protein substance which acts as a waterproof covering and provides the protective coating for the living cells of the Derma
Color of the Skin
· Partly dependent upon
1. The presence of the ___________________________________
2. The ___________________________ of the superficial capillaries
ARCHAIC DESCRIPTION FROM THE TEXT BUT YOU SHOULD BE FAMILIAR WITH THE TERMINOLOGY UNTIL THE TEXT IS CHANGED OR UPDATED:
· ‘Deep brown or blackishness of an African American, and the “tanned” color of some of the white race’
· Color is _________________________________________________________
PIGMENT (AKA: __________________________)
Consists of ______________________________________________ of very small size which are packed closely together within the cells of the Epidermis
· Deposited in the cells of the deepest stratum
· _____________________________________________________
· Exposure to sunlight involves increase of pigmentation as a protection for the deeper structures
· Melanin may be totally lacking in some persons
· _________________________________________
· Partial albinism may also occur
· Some may have patches of skin that are pigment-free
· Moles are localized spots of _____________________________
· _____________________________ are common in many
· Elderly people get small areas of pigmentation spots (think “_________________________”)
SECOND PIGMENT (CAROTENE)
· In the ______________________________ layer and fat of the Derma and superficial fascia
· Pigment varies in quantity from time to time in each individual
· In old age, this yellow pigment contributes greatly to the

Glossary
-epidermis: top layer of skin
-areolar tissue: fibrous connective tissue having the fibers loosely arranged in a net or meshwork
-adipose: satty tissue
-dermis: 2nd layer
-subcutaneous layer (aka, Hypodermis): bottom layer
-fascia: bands or sheets of connective tissue found below the skin; tissues that attach, stabilize,
impart strength, maintain vessel patency, separate muscles, and enclose different organs
-subcutaneous tissue: the deepest layer of your skin
-connective tissue: tissue that connects, supports, binds, or separates other tissues or organs, typically having relatively few cells embedded in an amorphous matrix, often with collagen or other fibers, and including cartilaginous, fatty, and elastic tissues. "A thin sheet of connective tissue"
-Deep fascia: dense connective tissue that is commonly arranged in sheets that form a stocking around the muscles and tendons beneath the superficial fascia
- tendon: fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.
- Ligament: tough fibrous band of connective tissue that serves to support the internal organs and hold bones together in proper articulation at the joints.
