Integumentary System (skin)

The reticular layer of the dermis

Individuals with phenylketonuria (PKU) have a genetic disorder that affects their ability to metabolize phenylalanine, leading to its accumulation in the body. However, the enzyme responsible for melanin production is not directly affected by the PKU mutation. While PKU can lead to lighter skin due to lower levels of certain amino acids, some melanin production still occurs because the body utilizes other pathways for pigment synthesis, allowing for some degree of skin pigmentation. Additionally, factors such as environmental exposure to sunlight can also influence melanin production in these individuals.

because those are the keratinocytes that are about the be shed... not really any other reason

People with high concentrations of the pigment melanin tend to have darker skin.

Ulcer

UVC radiation is almost completely absorbed by the ozone layer and does not affect the skin as it doesnt get to us.

The Subcutaneous Layer.

Adrenalin is a hormone made by the adrenal glands.

Technically no. It is just a blood clot. It is dried up blood

The skin is part of the Integumentary System, and is the largest organ in the body.

holocrine,apocrine,merocrine are the terms used to designate the secretory cells (glands),depending on how these cells release their secretions.

holocrine-release their secretions by lysis of the cell.

apocrine-by budding off cell membrane into vesicles.

merocrine-by exocytosis into ducts.

ascending order of tissue damage during secretion

merocrine

Sweat glands are of 2 types Eccrine(a type of merocrine) and Apocrine.

The term Apocrine sweat gland is a misnomer, since they dont secrete by apocrine mechanism, as earlier believed.

Regarding differences, both types glands vary in terms of number,distribution,nature of secretions,activity,histology,innervation,etc

I can now answer only a few things and the rest if left unanswered will be discussed by others.

first eccrine, numerous, all over the body,clear,odorless secretions rich in Nacl and H20.

next apocrine, limited,eyelids ,ear canal,alae of nose,armpits,breasts,pubic and perianal region,etc,odorless,oily,thick,opaque,secretions that gain odor after bacterial decomposition.

Very small pinpoint hemorrhages under the skin are known as what?

Shearing of the skin is when skin sticks to a surface while muscles slide in the direction the body is moving.

Most of the pigmented lesions are moles. Other benign pigmented lesions are haemangioma, dermatofibroma, solar keratoses.

Malignant pigmented lesions are malignant melanoma, Bowen's disease, and basal cell carcinoma.

Moles should be carefully watched for change in size, colour, ulceration, bleeding and crusting and avoid exposure to too much Sunlight and the use of sun lotion with UVA / UVB protection.

The skin response for a low body temperature would be causing the small hairs (erector pili) to rise. This causes "goose bumps". In other animals this action would hold the heat in. But we do not have that. Also the blood flow would go deeper and the skin would appear bluish. If a higher body temperature would occur, the skin would produce sweat to cool us and also the skin would appear red so that heat would be carried to the surface by the now dilated blood vessels.

Sebaceous glands are part of the pilosebaceous unit and so are found wherever hair follicles are located where Sebaceous filaments are buildups of skin debris, bacteria, and sebum around hair follicles. They usually appear white, yellow, or gray in color, and look like tiny plugs. I also don't have any know how about this. I get this info by visiting website Smarthealthkick.

They both contain sensory receptors.

Eight normal age-related changes of the integumentary system include the thinning of the epidermis, which can lead to increased fragility of the skin; a decrease in collagen and elastin production, causing loss of elasticity and wrinkles; and reduced oil production, resulting in drier skin. Additionally, there may be a decline in the number of melanocytes, leading to gray hair and age spots. Blood vessels in the dermis may become more fragile, increasing the risk of bruising. Lastly, the rate of skin cell turnover slows down, which can impair wound healing.

If you break it enough for blood to come out you can get a blood disease like HIV. Also if you break it with something rusty or dirty there's tetnus. I know there are a TON more but those are just the one's I know about.

This described rhubarb. It is long and thin, and looks a bit like celery. However, the stalks are a rich red color.

itz called a weenis -im seious my brother started sayin that but i didnt beleeve him so i looked it up tha internet and itz tru

turn cyanotic

does ring worm effect the epidermis

Disincrustation is a term used in skin care industry. It describes a process of dissolving dead skin cells and debris on the surface of the epidermis (outermost layer of the skin). Skin care therapist often use disincrustation liquid or solution before they do extractions to open the pores and have better results from the facial.
