Sebum

This gland produces sebum

Sebaceous gland

The production process of injured skin to restore itself to normal thickness

Hyperproduction

Glands that excrete perspiration, regulate body temperature and detoxify the body.

Sudoriferous

What is the average pH of the acid mantle?

5.0 -6.0

Tube like depressions with oil glands attached are..

Follicles

What is TEWL???

Transepidermal Water loss (evaporation of the skins surface)

What cells are found in the Stratum granulosum?

Strain basal, melanocytes, the spinosum.

This layer is stratum is only present in the thicker skin of the palms and soles?

Lucidum

This strain serves as effective barrier to any chemicals that might harm the living cells beneath them..

Corneum

The stratum insureds production of new skin cells. It also provides vital protection against viruses bacteria parasites or any other forms of pathogen or toxin.

Corneum

The stratum is the thickest layer of the four it protects the hands and feet? Hint it’s underneath the corneum..

Stratum lucidum

What is the bottom layer of the epidermis?

Lymph vessel

Within the skin through… 🐛

Capillaries

This “ingredient” is a natural intercellular fluid that helps hydrate the skin

Hyaluronic acid

What 5 components make up the dermis?? F L L L M

Fibroblasts (cell stimulaters) Lymphocytes (fights infections) Langerhans cells ( guards cells) Mast cells ( involved in allergic reactions) Leukocytes ( 🩸 fight against injections)

LEUKOCYTES

What are dermal papillae??

Membranes of ridges &grooves that attaches to the epidermis

A colony of microorganisms that adhere to environmental surface/ human body that secrete a sticky/ protective coating that cements them together. (Making them hard to penetrate)

Hair papillae are cone-shape elevation at the base of the follicle that fit..

Into the hair bulb

The lipid substances between Corneum cells that protect the cells from water and irritation.

Intercullar matrix

Hydrolipidic film

Is an oil water balance that protects the skin surface

This is the top layer of the dermis! Next to the epidermis.

The papillary layer!

The deepest layer of the dermis, contains proteins, college and elastic that give the skin its strength and elasticity

Reticular layer

This gland protects the surface of the skin, whereas Sudoriferous glands excrete perspiration and regulate body temperature

Sebaceous gland

SUBCANTANEOUS

This layer provides a protective cushion& energy storage for the body, whereas fibroblast stimulate cells, collagen and amino acids.

Subcutaneous

This is also known as the Subcutis tissue!!

Adipose tissue

This gland excretes perspiration and detoxify the body

Sudoriferous

This stimulates cells that form proteins
