• Yellowish skin coloration which is many times caused by liver disease
• “Bili” lights are used to treat this condition in newborns.
• Jaundice

• Bluish skin color due to low oxygenation of the blood.
• Cyanosis

• Sweat glands that are active throughout life. Respond to elevated body temperature, release sweat onto the surface of the skin through a pore.
• Eccrine glands

• Sweat glands that become active at puberty. Produce moisture when a person is upset, frightened, in pain or sexually aroused. Duct opens into a hair follicle.
• Apocrine gland

• Projection of dermal blood vessels at the base of a hair follicle that supplies nourishment.
• Hair papilla

• This layer consists of adipose tissue and loose, areolar C.T. Major blood vessels that supply the skin are located here.
• Subcutaneous layer

• These are formed by ridges in the dermis. They are determined by genetics, but are also influenced by fetal movement in the womb, so that even identical twins each have a unique set of these.
• Fingerprints

• This epidermal layer is only present in the thicker skin on the palms of the hands and soles of the feet.
• Stratum lucidum

• This is the deepest layer of the epidermis. Cells in this layer frequently undergo mitosis, producing new cells to compensate for those lost by desquamation, (sloughing).
• Stratum basale
![Page 10: 1 Yellowish skin coloration which is many times caused by liver disease “Bili” lights are used to treat this condition in newborns. Jaundice.](https://reader036.fdocuments.in/reader036/viewer/2022062500/5697bffa1a28abf838cc0896/html5/thumbnails/10.jpg)

• This is the outermost layer of the epidermis. It is composed of 20-30 layers of dead, flattened keratinocytes, and provides a tough, waterproof barrier for the skin.
• Stratum corneum
![Page 11: 1 Yellowish skin coloration which is many times caused by liver disease “Bili” lights are used to treat this condition in newborns. Jaundice.](https://reader036.fdocuments.in/reader036/viewer/2022062500/5697bffa1a28abf838cc0896/html5/thumbnails/11.jpg)

• Smooth muscle attached to the base of each hair follicle. Contracts when the body chills, producing “goose bumps.”
• Arrector pili muscle

• This can develop when a person or animal lies in one position for a long period, so that pressure on prominent body parts restricts blood flow to the tissue, causing tissue necrosis (death).
• Methods used to prevent formation of this include: frequently changing body position, massaging the skin, adequate fluid intake and eating foods rich in protein.
• Decubitus ulcer

• Acne is caused by a disorder of this gland.• Gland associated with each hair follicle; it
secretes sebum
• Sebaceous gland

• The 4 cardinal signs of this are: redness, swelling, heat and pain.
• The body’s normal response to an injury or stress.
• Inflammation

• The body’s normal response to this is goose bumps, vasoconstriction of the dermal blood vessels and shivering.
• Hypothermia
![Page 16: 1 Yellowish skin coloration which is many times caused by liver disease “Bili” lights are used to treat this condition in newborns. Jaundice.](https://reader036.fdocuments.in/reader036/viewer/2022062500/5697bffa1a28abf838cc0896/html5/thumbnails/16.jpg)

• The body’s normal response to this is vasodilation of the dermal blood vessels and sweating.
• Hyperthermia

When phagocytes eat an infectious agent, they release this chemical which causes the hypothalamus to raise the set point for body temperature, resulting in a fever.
Interleukin 1

• Type of burn that only involves the epidermis.
• Superficial, partial-thickness burn. Heals in a few days to 2 weeks, with no scarring.
• First degree burn

• Type of burn that involves the epidermis and partial dermis; Blisters form; accessory structures are spared.
• Deep, partial thickness burn. Can heal with no scarring and maintain function of the skin.
• Second degree burn.

• Type of burn that involves the epidermis and full dermis. Accessory structures are destroyed. Heals with scarring and loss of functional skin, (can’t sweat, form goose bumps, no hair).
• Deep, full thickness burn. Many times requires a skin graft.
Third degree burn

• Production of this chemical is influenced by both genetics and exposure to UV radiation; UV radiation also causes it to darken.
• Melanin
![Page 23: 1 Yellowish skin coloration which is many times caused by liver disease “Bili” lights are used to treat this condition in newborns. Jaundice.](https://reader036.fdocuments.in/reader036/viewer/2022062500/5697bffa1a28abf838cc0896/html5/thumbnails/23.jpg)

• Small, conical projections of dermis that increase surface area contact with the epidermis; helps ensure enough nutrients and oxygen can diffuse to the epidermis from the dermis.
• Dermal papillae

• Thinning hair, thinning epidermis, decreased sensory receptors, decrease in collagen and elastin fibers, decrease gland secretions, decrease in subcutaneous fat – these are the affects of ____
• Aging
