1.  NAME TWO IMPORTANT FUNCTIONS OF THE DERMAL PAPILLAE BLOOD VESSELS
2.  NAME THE TWO PARTS OF THE HAIR:
3.  WHAT IS THE HAIR FORMED BY:
4.  WHEN THERE IS AN ACCUMILATION OF MELANIN AT ONE SITE THIS CAUSES:
5.  WHAT CELLS IS THE NAIL MADE UP OF?
6.  TRUE OR FALSE:  •Hair is found over most of the body –No hair on soles, palms, nipples, lips, and parts of external genitalia
7.  IDENTIFY THE FOLLOWING GLAND: Produce cerumen Found in external auditory canalKeeps foreign particles and insects out of auditory canal
8.  NAME THE PART OF THE SKIN THAT PROVIDES THESE FUNCTIONS?  Serves as a boundary Protects the body against Entrance of pathogens Ultraviolet radiationExcessive water loss
9.  WHAT PIGMENT IS RESPONSIBLE FOR SKIN COLOR:
10.  NAME THE TISSUE THE EPIDERMIS IS MADE UP OF?
11.  NAME THIS LAYER OF THE SKIN?  •Outermost layer •Numerous layers of dead, flat, keratinized cells •Constantly sloughed off and replaced –It takes approximately two weeks for new cell to complete their journey through the epidermis
12.  NAME THE MUSCLE THAT CAUSE THE FOLLOWING ACTION:  •Contracts and raises the hair in the follicle on end •Causes “goose bumps”
13.  NAME ONE FUNCTION OF MELANIN:
14.  IDENTIFY THE FOLLOWING SUDORIFEROUS GLAND:  •Empty secretion into hair follicle •Located in axillary and genital regions •Activate at puberty •Milky sweat due to proteins and fats •Odorless –BO due to bacterial decomposition
15.  WHAT IS ANOTHER NAME FOR THE HYPODERMIS?
16.  WHAT IS ANOTHER NAME FOR SUDORIFEROUS GLAND?
17.  NAME TWO FUNCTIONS OF THE NAIL?
18.  WHERE IS THE HYPODERMIS LOCATED
A.
B.
C.
D.
E.
19.  NAME THE TWO TYPES OF TISSUES THAT MAKES UP THE HYPODERMIS:
20.  NAME THIS PART OF THE HAIR?  •Contains the hair root •Bulb of follicle is site of new hair growth –Nourished by dermal papillae •New cells from bulb become part of the root
21.  NAME THE THREE STRUCTURES OF THE NAIL:
22.  IN WHAT AREAS IS THE SKIN THINNEST.  (SELECT ALL THAT APPLIES)
A.
B.
C.
D.
E.
23.  IDENTIFY THE DEFINITION:  •Form from epidermis that grows inward into the dermis
24.  NAME THIS PART OF THE SKIN:  •Conelike projections of dermis that fit into recesses of epidermis •Possess blood vessels, touch receptors •Forms fingerprints and toe prints
25.  NAME THE TWO MAJOR LAYERS OF THE SKIN?
26.  NAME THE LAYER OF THE EPIDERMIS:  –Innermost layer of epidermis –Site of mitotic cell division –New cells move from the stratum basale towards the surface –As cells move they form distinctive layers in the epidermis •Cells acquire keratin as they migrate through the epidermal layers
27.  IDENTIFY THE FOLLWING SWEAT GLAND:  •Occur all over the body •Secrete sweat onto skin surface directly •Cleary, watery perspiration •Activated with increase in body temperature •Functions to cool the body
28.  IDENTIFY THIS PART OF THE SKIN:  –Composed of fibrous connective tissue •Collagen: strength and toughness •Elastic fibers: extensibility and elasticity
29.  NAME THE THREE TYPES OF INTEGUMENTARY GLANDS
30.  NAME THE THREE TYPES OF SKIN PIGMENTS:
31.  NAME THE FIVE MAJOR FUNCTIONS OF THE SKIN IN ALPHABETICAL ORDER:
32.  WHAT DETERMINES THE RATE OF MELANIN PRODUCTION
33.  IDENTIFY THE FOLLOWING GLANDS: Oil-producingEmpty sebum into hair follicleFunctionsIncrease pliability and softness of skin and hairLimit evaporative water lossInhibit bacterial growth
34.  NAME THE PART OF THE SKIN THAT PERFORMS THESE FUNCTIONS?  •Attaches skin to underlying tissues and organs •Site for subcutaneous injections •Site of white blood cell action •Heat insulator •Fat storage •Conserve body heat and retards penetration of external heat
