Front 1

A group of tissues that performs a specific function is a

Back 1

Organ

Front 2

The two major components of the integumentary system are

Back 2

the cutaneous membrane and the accessory structures

Front 3

The portion of the integument that is made up of dense irregular connective tissue containing collagen & elastin is

Back 3

Dermis

Front 4

The epidermis provides a physical barrier due largely to the presence of

Back 4

Keratin

Front 5

The cells producing the pigment responsible for skin color are the

Back 5

Melanocytes

Front 6

Cells of the skin that are active in the immune process

Back 6

Langerhans Cells

Front 7

Beginning at the basal lamina and traveling toward the free surface, the epidermis includes the following layers

Back 7

Germinativum, spinosum, granulosum, lucidum, corneum

Front 8

The layer of the epidermis only found in the thick skin of the palms and soles is

Back 8

Stratum Lucidum

Front 9

As the cells are pushed from the deeper portion of the epidermis toward the surface, what happens

Back 9

they degenerate and die

Front 10

Layer where mitosis occurs to replace cells lost from outer layer of epidermis

Back 10

Stratum Basale

Front 11

Layer of dead cells filled with keratin

Back 11

Stratum Corneum

Front 12

Production of keratohyalin granules; lamellar bodies release lipids; cells die

Back 12

Stratum Granulosum

Front 13

Dispersion of keratohyalin around keratin fibers; layer appears transparent; cells die

Back 13

Stratum Lucidum

Front 14

Production of keratin fibers; formation of lamellar bodies; limited amount of cell division.

Back 14

Stratum Spinosum

Front 15

Has no direct blood supply, contains kerantinocytes

Back 15

Epidermis

Front 16

Is mostly connective tissue and layer where corpuscles of touch are found

Back 16

Dermis

Front 17

The two major components of the dermis are

Back 17

papillary layer and reticular layer

Front 18

The layer of the dermis closest to the epidermis and its responsible for fingerprints and footprints

Back 18

Papillary Layer

Front 19

The layer of the dermis responsible for most of the structural strength of the skin and responsible for cleavage line and striae

Back 19

Reticular layer

Front 20

Receptors in the skin that are sensitive to touch

Back 20

Meissner's corpuscles & Pacinian Corpuscles

Front 21

The primary pigments contained in the epidermis

Back 21

Carotene and melanin

Front 22

The function of melanin in the skin is

Back 22

Protection from ultraviolet light

Front 23

The accessory structures of the integument include

Back 23

hair follicles, nails, sebaceous glands, and sweat glands

Front 24

Hair

Back 24

colored by melanin

Front 25

The base of a hair follicle is enlarged into an onion-shaped structure called

Back 25

Bulb

Front 26

Structures of a hair and hair follicle in order form the outside of the hair follicle to the center of the hair

Back 26

Dermal root sheath, epithelial root sheath, cuticle, cortex, medulla

Front 27

The outer surface of a hair shaft is made up of

Back 27

thin, flat, scale-like cells arranged like shingles

Front 28

Hair is surrounded by and is a product of cells of the

Back 28

epidermis

Front 29

The portion of the hair follicle where the cell divisions responsible for growth occur is the

Back 29

matrix

Front 30

You can cut hair without feeling pain because

Back 30

the shaft of the hair consist of dead cells

Front 31

An arrector pili muscle

Back 31

can cause the hair to stand up straight

Front 32

Two types of exocrine glands in the skin are

Back 32

Sebaceous and sweat glands

Front 33

The glands usually associated with hair follicles

Back 33

Sebaceous glands

Front 34

Lubricates the surface of the skin and hair, consist of dead cells and fatty substances, in excess may cause seborrhea

Back 34

Sebum

Front 35

Perspiration is the substance produced by

Back 35

Sudoriferous glands

Front 36

The primary function of sensible perspiration is to

Back 36

Reduce body temperature

Front 37

Alveolar glands that produce a white, oily substance; usually open into hair follicles

Back 37

Sebaceous Glands

Front 38

Coiled tubular glands that secrete a hyposmotic fluid that cools the body; most numerous in the palms and soles of feet

Back 38

Merocrine sweat glands

Front 39

Secretions from these coiled tubular glands are broken down by bacteria to produce body odor; found in the axillae, genetalia and around anus

Back 39

Apocrine sweat gland

Front 40

Apocrine sweat glands can be controlled by

Back 40

The autonomic nervous system and the endocrine system

Front 41

Glands that are present in the external auditory meatus are

Back 41

Ceruminous glands

Front 42

The stratum corneum of the nail fold grows onto the nail body as the

Back 42

Lunula

Front 43

The lunula of the nail appears white because

Back 43

blood vessels cannot be seen through the thick nail matrix

Front 44

The cuticle of the nail consists of

Back 44

Srtatum Corneum

Front 45

Most of the nail is produced by the

Back 45

nail Matrix

Front 46

nails are found from

Back 46

Epidermal cells

Front 47

The portion of a nail that extends past the end of the finger is the

Back 47

free edge

Front 48

The skin aids in maintaining the calcium and phosphate levels of the body at optimum levels by participating in the production of

Back 48

Vitamin D

Front 49

Which process increases heat loss from the body

Back 49

Dilation of dermal arterioles

Front 50

In third-degree burns, both the epidermis and dermis of the skin are destroyed. What would not occur

Back 50

Increased sweating

Front 51

The development of gray hair is due to

Back 51

the reduction of melanocyte activity

Front 52

If damaged, which may be replaced by fibrous tissue

Back 52

nerves, muscles and hair follicles

Front 53

white blood cells at the scene of a deep wound

Back 53

engulf microbes and cell debris

Front 54

sometimes, scar tissue formation continues to form after the repair is complete. this is called

Back 54

Keloid

Front 55

After a cut into the dermis, the stratum germinativum cells begin to migrate

Back 55

toward one another to close the wound

Front 56

During the repair process of a wound, the number of capillaries at the wound site

Back 56

increases in number
