Integumentary System (skin)

I've been there, my friend. I learned that and aced my test. Lets move on to cells. In skin cells, there is a hard outer covering. Inside, is the cell membrane. I guarantee you that your teacher will be impressed.

epidermis

When the epidermis is slightly injured, new skin cells are formed to replace the ones that were lost in the damaged area. Your body works quickly and smartly to cover up that area before an infection may occur. If the epidermis is more than slightly injured, you should get some serious attention before an infection occurs. However, in both cases, your skin will eventually repair and makes repairs to the burned or hurt area of skin.

1- it form barrier that helps prevent harmful microorganisms and chemicals from entering the body

2- it also prevent the loss of life-sustaining body fluids

3- it protect the vital structures inside the bOdy from injury and from the potent ally damaging ultraviolet rays of the sun

The dermal reticular layer; this layer is the location of a lot of structures such as the hair follicles and the blood vessels.

THere are many barriers to prevent foreign organisms and viruses from entering your body. These include the skin, the mucous membranes of the respiratory system, the stomach acid, the enzymes in your tears, and the immune system.

Some diseases and disorder that affect the integumentary system include acne, albinism, alopecia, blisters, burns, calluses, cancer, cellulitis, chickenpox, corns, cutaneous anthrax, dermatitis, eczema, epidermolysis bullosa, folliculitis, furunculosis, granuloma annulare, herpes, hirsutism, impetigo, intertrigo, keratosis pilaris, lupus, melasma, onychomycosis, orf, paronychia, pityriasis, pressure ulcers, psoriasis, rosacea, scleroderma, seborrhea, tinea, urticaria, vitiligo, warts. psoriasis, acne vulgaris, tinea pedis Eczema

The capillaries are contained within the dermis and and nutrients that the epidermis requires diffuses up to it.

According to Wikipedia:

"[Olive skin is n]amed as such for its olive hue, or sun tanned appearance, it usually refers to a natural skin tone."

1. What will happen is that when you touch the hot object the nervous system will send a signal to the brain which will make you react to the hot object and that is what happen when you touch the hot object . Example : a hot stove , a hot light bud, the seat in the summer which is like burning your bum ,and that are some example for hot object...or it will hurt alot

usually they would use a skin shaver (something just like a potato peeler but it slices thinner cuts) and use that to cover it up

they usually asked the patient where they would like to take the skin from

usually the patient picks the buttocks or somewhere that is always covered up.

the sun has UVA or UVB rays and if u are in the carribean wear alot of sunscreen and stay in shade for a short pieriod of time.

Accumulate the melanin granules on their superficial portion, forming a pigment that protects DNA from UV radiation

They are pressure receptors so respond to their stimuli-pressure :) hope this helps

Your skin is made up of three different layers. The epidermis is the outside layer that you can see, the dermis is under the epidermis and plays a role in sensation, and the third layer is subcutaneous fat and helps your body stay warm.

The dermal layer responsible for fingerprints is the papillary layer.
stratum germinativum

The two ways would be sweating and vasodilation. Sweating causes the sweat glands, know also as the sudoriferous glands, to release sweat. As the sweat evaporates it cools the skin. In order to take advantage of this cooling opportunity the capillaries in your skin vasodilate, which means that they open up to allow more blood to come to the surface to release heat from inside the body.

the dermis is dermis is the thickest layer of the integumentary system

The outer layer of the skin is the epidermis. The term epidermis means on top of the dermis. Actually the dermis is what gives color to the skin. The epidermis is a dry layer but it does give a waterproof coating.

No, it is not. The epidermis is in fact part of the integumentary system. This system comprises of the skin (epidermis, dermis and subdermis), and its appendages (including hair and nails).

Keratenocyles

Of course, since the genetic material which is your DNA can be found on the nucleus of your skin cells.

yes, the dermis is much thicker than the epidermis

The papillary layer of the skin is one of two layers of the dermis.

yes all the time
