About skin

Back 35

Largest organ in body

Weighs more than 20 pounds in adult

Aka integument

Cutaneous membrane

Front 36

Skin functions

Back 36

Protection

House nerve receptors

Secrete fluids

Regulate temperatures

Front 37

Sensory receptors

Back 37

Located within middle layer of ski

Detect:

*Temperature

*Pain

*Touch

*Pressure

Nerve endings convey messages to brain and spinal cord

Front 38

Sweat glands

Back 38

Assists body in maintaining internal temp

Creates cooling effect when sweat evaporates

Front 39

Protection

Back 39

Primary function

Forms 2-way barrier

*keeps out pathogens

*prevents critical body fluids from escaping

Protects underlying tissue

Front 40

Sebaceous glands

Back 40

Oil glands

Produce sebum

Lubricates the skin surface

Front 41

Temp regulation: to cool skin

Back 41

Sweat evaporation

Dilate superficial blood vessels to release heat

Front 42

Temp regulation: To conserve heat

Back 42

Constrict superficial blood vessels to keep warm blood away from surface

Continuous fat layer acts as insulation

Front 43

Epidermis

Back 43

Thin, outer membrane layer

Front 44

Dermis

Back 44

Middle, fibrous connective tissue layer

Front 45

Three layers of skin

Back 45

Epidermis

Dermis

Subcutaneous layer

Front 46

Subcutaneous layer

Back 46

Innermost layer of fatty tissue

Front 47

About Epidermis

Back 47

Composed of stratified squamous epithelium

Has no blood supply or connective tissue

Depends upon deeper layer of skin for nourishment (basal layer)

Front 48

Stratified squamous epithelium

Back 48

Flat scale-like cells

Arranged in overlapping layers called strata

Front 49

Basal layer

Back 49

Deepest layer of epidermis

Cells continuously grow and push old cells toward surface

Old cells called keratin

Front 50

Keratin

Back 50

Cells shrink,die, and fill with hard protein forming keratin

Keratinized skin acts as a barrier to infection

Front 51

Melanocytes

Back 51

Special cells of basal layer

Produces black pigment melanin

Gives skin color

Protect against uv rays of sun

Front 52

About Dermis

Back 52

Aka corium

Located between epidermis and subcutaneous layer

Name means true skin

Living tissue with very good blood supply

Front 53

What is dermis composed of?

Back 53

Connective tissue and collagen fibers

Strong fibrous proteins give dermis flexible strength

Front 54

Dermis houses:

Back 54

Hair follicles

Sweat glands

Sebaceous glands

Blood vessels

Lymph vessels

Sensory receptors

Nerve fibers

Muscle fibers

Front 55

Subcutaneous layer

Back 55

Aka hypodermis

Third and deepest layer

Aka hypodermis

Composed of fat cells called lipocytes

Protects the deeper tissues of the body

Acts as insulation for heat and cold

Front 56

Accessory organs

Back 56

Located in dermis

Hair

Nails

Sebaceous glands

Front 58

Arrector pili

Back 58

Slip of smooth muscle

Causes hairs to stand up

Front 59

Nail body

Back 59

Flat plate of keratin

Front 60

Nail bed

Back 60

Connects nail body to underlying tissue

Front 61

Lunula

Back 61

Half-moon white area at base of nail

Front 62

Cuticle

Back 62

Soft tissue that covers the nail root

Front 63

Sebaceous glands

Back 63

Open into hair follicles

Secretes the oil sebum

Front 64

Sebum

Back 64

Lubricates hair and skin

Prevents drying and cracking

Front 65

Sweat glands

Back 65

Aka sudoriferous glands

Coiled gland in dermis

Sweat travels to surface in sweat duct

Front 66

Sweat pore

Back 66

Surface opening

Front 67

Sweat glands continued...

Back 67

2 million throughout body

Sweat aka perspiration

*cools body as evaporated

*contains small amount of waste products

*normal colorless and odorless

Front 68

Apocrine glands

Back 68

Found in pubic and underarm areas

Thicker sweat that can produce an odor
