the movement of muscles under the skin is what gives rise to the formation of prominencesfoldshollowsfurrows
for every muscle pulling in one direction there is another muscle which returns it to position
origin refers to the end of a muscle which is attached to a fixed point
on the face, the origin is usually on an immovable bone or cartilage
insertion refers to the end of a muscle which is attached to a movable part of the body or to the skin
it is upon the insertion that the pull of a muscle is applied

orbicularis oris known as the puckering or whistling muscle
this is the sphincter muscle that encircles the mouth orbicularis oris
contraction of the orbicularis oris closes and puckers the lips
unlike the sphincter of the eye, the orbicularis oris is composed primarily of fibers from other facial and lip muscles

restorative art the care of the deceased to recreate natural form and color
form refers to the shape of the surface structure , head , which is recognizable by its outline and surface movement. Involves three dimensions: length width and projection.
color refers to those rays of light reflected from the surface, skin color, which is basically determined by its spectral composition. Also, shadow and highlights.
minor restoration require a minimum of effort, skill, and time to complete
major restoration take a longer period of time and require extensive skill
time table restoration treatments for pre-embalming corrective positioning eyes mouth nose suturing in place
time table restoration treatments for embalming color, swelling
time table restoration for post embalming removal of mutilated tissue treatment of swelling wax: surface, deep wound
restorative art as we know it has reached its highest level of performance mainly in USCanada
restorative art goes back to egyptians
unlike today- egyptians focused on what type of restoration whole body for reincarnation
demi-surgery the art of building or creating parts of the body which had been destroyed by accident, disease, decomposition or discoloration and making the body perfectly natural and lifelike
physiognomy the study of structures and surface markings of the face and features
physical anthropology the study of humans as biological species with interest in evolution and modern human variations
taxonomy an orderly classification of plants or animals by their presumed natural relationships
morphology means shape – study and form of structure of organisms and their structural features
two of the most important influences on human form and behavior are environmentnutrition
races european asian african
leptorrhine = narrow nose
mesorrhine = intermediate nose
platyrrhine wide nose
skin color determined by the amount of melanin, carotene, and blood present.
the darker the skin- the more melanin is present
cells within the dermis that produce melanin are called melanocytes
melanosomes in black skin larger more oval and singly dispersed
melanosomes in white skin smaller and more aggregated
melanin protects the skin from the rays of the sun and absorbs ultraviolet light
stratum corneum top layer of skin
the stratum corneum in african and asiatic races is more compact has greater permeability
which kind of skin tone contains 40-60% more sebaceous oil producing glands darker skin
dark skin can make white massage cream turn gray
the use of what can result in ashen skin titanium oxide talcother white powders in cosmetics
xeroxes = ashen skin
the use of orange or yellow tinted cosmetic powders may be preferred for people with black, bronze, red or yellow complexions
anatomical position the body is erect, feet together, palms facing upward, upper limbs are at the sides with thumbs pointed away from the body
superior towards the head
inferior towards the feet
anterior (ventral) towards the front
posterior (dorsal) towards the rear or caudal end
medial towards the midline
lateral towards the side, away from the midline
projection a part extending beyond the level of its surroundings
recession the withdrawal of a part from its normal position
depression a hollow or concave region
protrusion the state or condition of being thrust forward or projecting
concave exhibiting a depressed or hollow surface, a concavity
convex curved evenly , resembling a segment of the outer edge of a sphere
