Integumentary

this aids in maintaining the calcium and phosphate levels of the body at optimum levels by participating in the production of vitamin D

The skin aids in maintaining ______ and ________ levels of the body at optimum levels by participating in the production of ______

Processes that increases heat loss from the body

It is an alveolar gland that produces a white, oily substance called sebum and usually open into hair follicles.

It is one of the functions if integumentary system wherein it allows your body to maintain its core internal temperature

Function of integ

white, oily, substance called ____ and usually open into hair follicles

Are most numerous in the palms and soles

Merocrine or ?

Responsible for the structural strength of dermis

Skin is most resistant to stretch along these lines

Can develop when the skin is overstretch

Contains blood vessels that supply the epidermis, removes waste, helps regulates

Increase friction and improve the grip of hands and feet

Produces and secretes sebum that helps nourish the hair

Superficial layer of epidermis

Stratified squamous epithelium

Pigments primarily responsible for hair, skin eye color

Melanin is produced by

Deepest layer of epidermis

Layer of epidermis that is only found on parts of the skin with no hair

Replaced Near time of birth by terminal hair

Columns of dead keratinized epithelial cells

Nail which is covered by skin

Nail matrix which is visible through the nail body

Eyelashes grow for ____ days and rest for ____ days

Hypodermis or ?

Functions of hypodermis

Hypodermis stores _____ in the form of ____

Red, painful and slight edema

Involve only the epidermis

Third degree burns or ?

Damage Epidermis and dermis

Injury to tissues caused by heat, cold, friction, chemicals or radiation

Skin is made up of two major tissue layers which are:

Superficial layer of the skin, consisting of stratified squamous epithelial tissue

Responsible for most of the strength of the skin

Layer of loose connective tissue that rests on the skin

TRUE or FALSE
The subcutaneous tissue is part of the skin or the integumentary system
True False

TRUE or FALSE
The epidermis contains no blood vessels.
True False

Cells of the epidermis are:

Cells in epidermis that produce a protein mixture called keratin

Cells in epidermis that produce the pigment melanin

Cells in epidermis that are part of the immune system

Cells in epidermis that are specialized epidermal cells associated with the nerve endings resposible for light touch and superficial pressure

Kertinocytes change shapes and chemical composition through ____

Come Let's Get Sun Burned (Superficial - Deepest)

deepest portion of the epidermis is a single layer of cuboidal or columnar cells

superficial to the stratum basale, it consists of 8-10 layers of many sided cells, cells are also spiny

consists of 2-5 layers of somewhat flattened, diamond-shaped cells; it derives its name from the presence of protein granules

thin, clear zone above the stratum granulosum, consists of several layers of dead cells

last and most superficial layer, composed of 25 or more layers of dead,overlapping squamous cells

dead cells with a hard protein envelope that is in the stratum corneum

Strata FUNCTIONS
this strata provide structural strength due to keratin within cells, prevents water loss due to lipids surrounding cells

Strata FUNCTIONS
this strata disperses keratohyalin around keratin fibers, (present in thick skin, absent in most thin skin)

Strata FUNCTIONS
this strata produces keratohyalin granules

Strata FUNCTIONS
this strata produces keratin fibers

Strata FUNCTIONS
this strata produces cells of the most superficial strata, produce melanocytes, protects against UV lights
