Sweat glands located in the armpits and groin area.Become active in puberty and release secretions through hair follicles A.Eccrine sweat gland B.Apocrine sweat gland C.Ceruminous glands

B.Apocrine sweat gland They release some cellular material which causes body odor from the beakdown of this material

B.Dermis Has the ability to stretch with little damage as during pregnancy

Most of the skin's accessory structures including the sweat glands,oil glands,and the hair are located in the --- A.Epidermis B.Dermis

B.Dermis May extend into the subcutaneous layer under the skin

The skin contains 2 layers A.Sebaceous gland and Eccrine gland B.Epidermis and Dermis

B.Pimple

The --- glands are saclike in structure and their oily secretions ---- lubricates the skin and hair and prevents drying. A.Sudoriferous Ceruminous B.Sebaceous Sebum

B.Sebaceous Sebum The ducts of the sebaceous gland open into the hair follicles

The term cutaneous refers to A.Nails B.Skin C.Covering

B.Skin

When the epidermis cells reach the surface of the skin the cells are flat ,filled with keratin, and horny forming the uppermost layer of the epidermis called A.Stratum germinativum B.Stratum coreum C.Melanin

B.Stratum coreum Coreum means horny Protective layer more prominent in thick skin

The blood vessels that supply the skin with nutrients and oxygen and help to regulate body temperature run through the --- layer A.Dermis B.Subcutaneous C.Epidermis

B.Subcutaneous This layer is rich in nerves and nerve endings including the ones that supply nerve impulses to and from the dermis and epidermis.

Coiled tube like structures located in the dermis and the subcutaneous tissue.Function to cool down the body. A.Sebaceous gland B.Sudoriferous gland

B.Sudoriferous gland (sweat) They release sweat or perspiration that draws heat from the skin as the moisture evaporates at the surface.

C.Eccrine sweat gland

The process by which the outer most layer of skin cells are constantly being replaced A.Dermal papillae B.Melanin C.Exfoliation

C.Exfoliation

As the epidermal cells die from the gradual loss of nourishment their cytoplasm is replaced by large amounts of a protein called --- which thickens and protects the skin A.Stratum corneum B.Dermal papillae C.Keratin

C.Keratin

If a sebaceous gland becomes blocked a sac of accumulated sebum may form and gradually increase in size. A.Blackhead B.Pimple C.Sebaceous cyst

C.Sebaceous cyst Can be removed by surgery

The --- is where cells are constantly dividing and producing daughter cells and pushed upward toward the skin's surface is called A.Keratin B.Stratum coreum C.Stratum basale

C.Stratum basale Also known as Stratum germinativum This is the growing layer and the deepest layer of the epidermis.

Babies are born with a covering that is produced by the sebaceous glands that resembles cream cheese called A.Sebaceous cyst B.Keratin C.Vernix caseosa

C.Vernix caseosa

Continuous bundles of elastic fibers connect the subcutaneous tissue with the dermis so there is no clear boundary between the 2. True or False

True

Consist of a mixture of dried sebum and karatin that collect at the opening of the sebaceous glands A.Blackhead B.Pimple C.Sebaceous cyst

A.Blackhead

Extensions of the dermis that extend upwards into the epidermis to get closer to the surface cells A.Dermal papillae B.FIngerprints C.Keratin

A.Dermal papillae Form a distinct pattern of ridges that help to prevent slipping when picking up an object.Known as fingerprints and footprints and can be used to ID someone

Surface portion of the skin in which the outer most cells are constantly lost through wear and tear A.Epidermis B.Dermis

A.Epidermis

Which layer of skin contains no blood vessels A.Epidermis B.Dermis

A.Epidermis

The cells in the deepest layer of epidermis produce a dark pigment that colors the skin and protects it from the harmful rays of sunlight called A.Melanin B.Keratin C.Dermal papillae

A.Melanin

The cells that produce melanin are the A.Melanocytes B.Dermal papillae

A.Melanocytes Irregular patches are called freckles

Between the stratum basale and the stratum corneum there are additional layers of A.Stratified epithelium B.Squamous epithelium

A.Stratified epithelium Amount vary do to the skins thickness

The dermis rest on the --- layer referred to as the hypodermis or superficial fascia.It connects the skin to the surface muscles A.Subcutaneous B.Cutaneous

A.Subcutaneous

The subcutaneous layer consists of Pick 2 A.Adipose(fat) tissue B.Connective tissue C.Nervous tissue

AB Adipose tissue (fat) - serves as insulation and energy reserves Connective tissue

Modified sweat glands Pick 3 A.Ceruminous glands B..Ciliary glands C..Mammary glands D..Apocrine glands

ABC Ceruminous glands - in ear canal and produce ear wax(cerumen) Ciliary glands- edge of eyelid Mammary glands - breast

The integumentary system includes accessory structures Pick 3 A.Glands B.Hair C.Nails D.Lungs

ABC Glands Hair Nails

Skin cells are being lost and replaced especially in areas of high wear and tear.Where are these areas Pick 4 A.Scalp B.Face C.Soles of feet D.Back E.Palms of hands

ABCE Scalp Face Soles of feet Palms of hands
