Front 10

What layer of the epidermis is a single layer of cupboidal shaped cells and is mitotically active?

Back 10

Stratum Basale

Front 11

What layer of the epidermis is:
-8 to 10 cell layers thick
-cells start to flatten as they reach the upper part of this layer?

Back 11

Stratum Spinosum

Front 12

What layer of the epidermis is 3-5 cell layers thick. The cells continue to flatten out, and cells begin to die forming water resistant barriers (keratinized

Back 12

stratum granulosum

Front 13

What layer of the epidermis is only present on the finger tips, palms and soles of the feet?

Back 13

Stratum Lucidum

Front 14

What layer of the epidermis is 20-30 cell layers in thickness, has flattened dead keratinocytes with no nuclei, the other layers are continually shed needing to be replaced and are approximately 3/4 of the epidermal thickness?

Back 14

stratum corneum.

Front 15

What layer of the skin is mostly connective tissue containing collagen and elastin fibers, few cells?

Back 15

The dermis

Front 16

What are the two layers or regions of the dermis?

Back 16

The papillary Region and the reticular region.

Front 17

The papillary region

Back 17

Is the superficial portion of the dermis, It includes the dermal papillae, meissner corpuscles, and the epidermal ridges

Front 18

What are the dermal papillae?

Back 18

tiny projections into the epidermis which increase the surface area of the Stratum Basale.

Front 19

What are the Meissner corpusclues?

Back 19

(corpuscles of touch) they are tactile receptors located at te apex of dermal Papilae

Front 20

What are epidermal Ridges?

Back 20

Epidermal Ridges = Dermatogyphs= finger priints.

Front 21

What part of the dermis is the deepest and largest portion and contains irregular connective tissue?

Back 21

reticular region.

Front 22

What layer of the skin is composed of adipose and areolar connective tissue, stores fat, and contains vessels and nerves that supply the skin?

Back 22

Hypodermis.

Front 23

What are the three pigments associated with pigmentation of the skin?

Back 23

Melanin, Carotene, and Hemoglobin.

Front 24

What is the brown or black pigment that is produced from melanocytes. Is made from amino acids Tyrosine?

Back 24

Melanin

Front 25

What are some disorders associated with melanin?

Back 25

albinism and vitiligo

Front 26

What is the pigmentation that is a yellow/orange pigment; not associated with Jaundice but associated with Vitamin A?

Back 26

Carotene

Front 27

What is the pigmentation that is a red/pin pigment, Is the oxygen carrying molecule in RBCs and is associated with translucent skin (skin lacking in melanin?)

Back 27

Hemoglobin

Front 28

What is another word for the Accessory structures of the integumentary System?

Back 28

Epidermal derivatives

Front 29

What are 4 epidermal derivatives (accessory structures) of the skin?

Back 29

Hair, Nails, Sebaceous glands, Sudiferous(Sweat) glands.

Front 30

What is the accessory structure that covers most of the skin surface, are columns of dead keratinized cels that are bonded together, and protects the body from heat loss and UV light?

Back 30

Hair= Pili/Pilus

Front 31

What is the accessory structure of the skin that are plates of tightly packed, keratinized epidermal cells?

Back 31

Nails

Front 32

What is the epidermal derivatives that: secrete sebum, an oily substance that softens and lubricates the skin water proofing, maintains hair follicles, contains antibacterial substances?

Back 32

Sebaceous glands

Front 33

What is the epidermal derivative that is associated with hair follicles, lips, and the pubic region and is not found on palms and soles?

Back 33

sebaceous glands

Front 34

What releases secretions onto the surface of the skin and is known as and accessory structure of the skin?

Back 34

sudoriferous glands (sweat glands)

Front 35

What are two types of sudoriferous (sweat) glands?

Back 35

eccrine glands and apocrine glands.

Front 36

What are the most common sweat gland that produces watery sweat that contains ions and small organic molecules and helps regulate body temperature and eliminates waste?

Back 36

Eccrine glands.

Front 37

What are the sweat glands that are common to the axilla and groin, produce watery secretions that are more viscous than norm. sweat, contains proteins and lipids, and also secondary sexual function

Back 37

Apocrine glands

Front 38

Two types of wound healing

Back 38

superficial and deep wound healing

Front 39

Superficial Wound Healing

Back 39

is when only the epidermis is damaged.
-the cells surronding the wound enlarge and migrate to fill the gap created by the injury.
-contact inhibition= migration ceases when the cells on both sides of the wound come into contract. Mitiosis in the stratum basale is stimulated, more cells are reproduced to make up for dead cells.

Front 40

Deep Wound Healing

Back 40

effects the dermis and has two phases the inflammatory phase and the migratory phase.

Front 41

What phase of deep wound healing does clots form over the wound, and local vasolidation, leukocytes, and fibroblasts move into the damaged area to repair?

Back 41

Inflammatory Phase

Front 42

in what phase of deep wound healing do scabs form, granulation or scar tissue is laid beneath the scab and vessels regrow?

Back 42

migratory phase.
