Three main layers of the skin:
Epidermis
Dermis
Subcutaneous
epidermis layer
outermost layer of your skin, and contains five additional layers
The five epidermis layers are
stratum cornea
stratum lucidum
stratum granulosum
stratum spinosum
stratum basale
Function stratum cornea
surface layer, which acts as a barrier against infections. Skin cells grow from the inside out; once cells reach the surface, they’re completely dead and keratinized.
These cells are packed closely together and serve as a water-resistant covering for the body. There’s an extensive amount of cell turnover in the skin, which is the process in which cells continuously die and are replaced by new ones. Your skin is constantly shedding these dead cells into the environment.
Function statum lucidum
Found just below the stratum corneum on the palms of the hands and soles of the feet only. This layer provides additional protection for these high-use areas. Cells in this layer appear clear.
Function stratum granulosum
Layer in which cells begin the protection process and are then distributed among the layers. These cells produce melanin, a type of protein that gives color to hair and skin.
Skin color has nothing to do with the numbers of melanocytes; instead, skin color is determined by the amount of melanin produced by the melanocytes
The stratum granulosum is the first layer not to be nourished by the dermis, so the cells start to die here, forming kreatin in the process.
KERATIN
Substance that constitutes your skin, hair and nails.
Stratum spinosum
Also known as the “prickle layer” for its spiny texture.
Stratum basale
Final and deepest layer of the epidermis which is composed of basal cells. This layer is responsible for renewing the epidermal cells.
dermis
Lies under the epidermal layer and is much thicker.
Located between the epidermis and the subcutaneous layer.
It contains blood and lymph vessels, as well as nerve fibers.
The dermis also contains hair follicles, sweat glands, and sebaceous glands.
Several types of connective tissue cells and collagen fibers support the hair follicles, sweat glands, and sebaceous glands.
Fibroblast cells
Produce fiber that helps to repair injuries.
Phagocytic cells
Protect the body by swallowing foreign materials such as bacteria.
histamine
Most cells contain histamine a substance that produces allergic reactions,
heparin
Most cells contain heparin, a substance that prevents blood clotting.
Collagen
gluey protein found in skin, connective tissue, bones, cartilage, tendons, and ligaments.
Collagen fibers provide the skin with its strength and elasticity. Because of collagen, skin can stretch- as it does during weight gains and pregnancy- and return to its normal shape again.
When the collagen fibers are overstretched, they break and form linea marks called stretch marks.
Whorls and loops
Found on the soles of the feet, the palms of the hands, and on the fingertips. These “prints” are actually formed from the ridges and furrows found in the dermis layer.
whorls and loops on the fingertips can help you grasp objects.
Location of Touch receptors in your fingertips
Closer to the epidermis so your fingers can detect very delicate surface changes.
Location of Pressure receptors
Deeper in the dermal layer, which explains why you can press on something firmly with your hands without discomfort.
Subcutaneous or hypodermal layer
Connective tissue layer that attaches the skin to the muscles and to other tissues lying beneath the skin.
Technically speaking, the subcutaneous layer isn’t actually part of the integumentary system because it’s made of connective tissue.
It’s sometimes called superficial fascia. Fascia is the tissue that provides support and protection for the organs.
The subcutaneous layer provides a link between the integumentary system and the other body system it covers. It serves to shape the body.
The subcutaneous layer also specializes in the production of fat.
Fascia
Tissue that provides support and protection for the organs.
Lipocytes
Adipocytes
Fat cells
stored in the subcutaneous layer in a special tissue called adipose tissue, which is made up of adipocytes.
Purpose of lipocytes
To manufacture and store large quantities of fat.
You need fat to maintain good health. It helps protect your underlying organs from mechanical shock as the body moves.
It also serves as insulation and, therefore, helps to keep the body warm.
When there’s no food to eat, fat becomes an energy source.
On the other hand, excessive fat stores are bad for your health.
The integumentary system is the body system that provides protective coverage for your _______?
Internal Organs
This integumentary system comprises the ____________
Skin
Hair
Nails
Sweat Glands
Sebaceous Glands
The skin’s functions are?
The skin provides protection from the outer environment.
The skin acts as a barrier against foreign pathogens.
The skin sends the pain, temperature, pressure, and touch stimuli to the brain.
When skin is exposed to the sun, it helps in synthesizing vitamin D, an essential vitamin needed to carry out various body functions.
How much space does the skin take up on average ?
20 square feet
How much does the skin weigh onaverage?
Between 7-9 punds
How many skin cells in the body?
300 million skin cells
Sweat glands are located….?
deep in the dermal layer, very close to the subcutaneous layer of the skin.
Two types of sweat glands
eccrine and apocrine
Eccrine sweat glands
numerous, important, and widespread throughout your body. These tiny coiled tubes reach the epidermis through crooked ducts called pores. Eccrine sweat glands produce a watery sweat.
Apocrine sweat glands
Found primarily in the axillae (armpits) and in the pigmented skin areas around the genitals. The apocrine sweat glands produce a thicker, milky secretion that can be odorous.
Mammary gland
Milk-producing, is actually a modified sweat gland, but it doesn’t work full time like the sweat gland. The mammary gland secretes milk only after the birth of a child.
Ceruminous glands
located in the skin that lines the external auditory canals. Instead of sweat, these glands secrete earwax, or cerumen.
Sebaceous glands
Flask-shaped, located in the dermis.
Commonly attached to hair follicles, the sebaceous glands secrete an oily substance called sebum, which is released through ducts in the hair follicles.
Sebum oils the hair, lubricates the skin, and prevents water loss.
Sebum
Oils the hair, lubricates the skin, and prevents water loss.
How many sweat glands in the body?
2 million
A single hair is composed of four basic parts:
hair shaft
hair root
hair follicle
papilla
hair shaft
the visible part of the hair
hair root
is embedded in the dermis
hair follicle
A bulblike attachment at the end of the hair. The follicle consists of the root and its coverings.
Papilla
A loop of capillaries enclosed within connective tissue.
lunula
The white crescent at the base of the nail. A nail grows from the lunula.
Fingernails grow indefinitely at the rate of about
1 milimeter per week.
Cuticle
The narrow band of the epidermis that extends from the nail wall onto the surface. The pinkish color seen beneath the nail is produced by underlying capillaries.
Common symptoms of various skin diseases:
pruritus or itching
erythema or redness
edema or swelling
scaling lesions
ulcers
hives
Pruritus (skin)
is due to histamine release from the skin cells in response to an allergic reaction.
Erythema (skin)
is caused by increased blood flow to the affected area of the skin.
Edema (skin)
is caused by fluid buildup in the affected skin area.
Scaling (skin)
is due to excess keratin buildup in the epidermis layer of the skin.
Lesion (skin)
the circumscribed area of the diseased skin tissue and is classified as primary and secondary.
ulcer, or an open lesion (skin)
results from tissue damage in the skin layers.
Hives (skin)
raised, irregularly shaped skin eruptions with red margins and pales centers. Hives usually result from an allergic reaction.
Common antibiotics used to treat bacterial infections:
Azithromycin (Zithromax)
Bacitracin (Bacitracin)
Bacitracin/ Neomycin/ Polymyxin B (Neosporin, Triple Antibiotic)
Cephalexin (Keflex)
Ciprofloxacin (Cipro)
Mupirocin (Bactroban)
Vancomycin (Vancocin)
Common antifungal medications:
Nystatin (Nystop)
Fluconazole (Diflucan)
Miconazole (Lotrimin)
Terbinafine (Lamisil)
Amphotericin B (Ambisome)
Primary skin lesions:
Abrasions
Contusions
Cysts
Exoriations
Lacerations
Macules
Papules
Polyps
Pustules
Vesicles
Wheals
Abrasion
the scraping away of epidermal tissue
Contusion
injured skin that’s intact and not broken
Cyst
a hollow cavity filled with liquid secretions
Excoriation
the superficial loss of tissue due to trauma, chemicals or burns
Laceration
broken skin layers or torn flesh
Macules
non-palpable discolored spots or patches
Papules
small, solid, circumscribed (rounded), raised areas. Examples include warts, moles, and pimples.
Polyp
a small growth protruding from a mucous membrane
Pustules
small, elevated, circumscribed, pus-containing lesions
Vesicles
blister-like elevations containing serous fluid. Examples include lesions due to dermatitis, burns, chicken pox, and scabies.
Wheals
localized areas of edema on the body surface. Examples include urticaria, or hives from allergic reactions
Secondary skin lesions
result from the healing process. As a primary skin lesion heals, scabs or crusts form over the affected area. These secondary lesions are composed of dry pus, lymph, or blood and may vary in color and thickness.
Cicatrix
is a scar from a wound that has healed.
Hypertrophied
Is a firm, raised, and thickened condition of a scar.
Keloid
Is a progessively enlarging, irregularly shaped scar tissue due to excessive collagen formation in the corium during repair.
Skin lesions are usually treated with
topical corticosteroids, antibiotics, and antiseptics, depending on the type of skin lesion.
list of common corticosteroids that are available to treat various skin disorders:
Betamethasone (Diprolene, Valisone)
Clobetasol (Temovate)
Desonide (Desowen)
Desoximetason (Topicort)
Fluocinolone (Capex)
Hydrocortisone (Cortef)
Triamcinolone (Kenalog)
Ulcer
An open sore or lesion caused by trauma, intense heat or cold, pressure, or bacterial infection. An ulcer is a depression of the epidermis.
It can progress to the erosion of the skin layers.
Pressure ulcers (or decubitus ulcers)
Are specifically caused by direct pressure due to prolonged immobility. When someone is sitting or lying down for long periods, ulcers may occur at the points that bear the most pressure, such as the heels, tailbone (coccyx), elbows and the back of the head. Patients that are immobile due to stroke, coma, or other serious diseases are at the greatest risk for developing pressure ulcers. Once an ulcer has formed, it doesn’t heal unless aggressive measures are taken to relieve the pressure. The ulcers may require surgery to remove dead or infected tissue.
decubitus ulcers
pressure ulcers
Pressure ulcer treatment includes
Keeping the affected area clean and dry.
Antibiotics, steroids, and pain reliever medications are sometimes used to provide symptomatic relief, decrease the inflammation, and treat infection if present.
Stage I ulcers
Have reddened skin, but the skin isn’t broken
Stage II ulcers
Can have broken or unbroken blisters that are reddened and/or irritated.
Stage III ulcers
Ulcers have skin breakage through all layers.
Stage IV ulcers
Ulcers go through all layers of skin and can affect muscles, tendons, and even bone.
Dermatitis
is a general term referring to any inflammation of the skin
