  • produce secretion of water and sodium chloride
A

Eccrine sweat glands

39
Q

Found in axillary and pubic regions

A

Apocrine sweat glands

40
Q

produce an oily secretion known as sebum, carried through ducts to the surface of the skin or to hair follicles

A

Sebaceous glands

41
Q
  • Found only in the dermis of the ear canals
  • Produce a waxy secretion known as cerumen to protect the ear canals and lubricate the eardrum
A

Ceruminous glands

42
Q

• Also known as cornification
• Process of keratin accumulating within keratinocytes
• Begin their life as offspring of the stem cells of the stratum basale

A

Keratinization

43
Q

• Being the body’s outmost organ, the skin is able to regulate the body’s temperature by controlling how the body interacts with its environment

A

Temperature homeostasis

44
Q

secreted to control body temperature

A
  • Sweat
  • Vasodilation
  • Vasoconstriction
45
Q

• An essential vitamin necessary for the absorption of calcium from food, is produced by ultraviolet (UV) light striking the skin
- Sterol molecule known as 7-dehydrocholesterol to calcitriol

A

Vitamin D

46
Q

• Minor mechanical damage from rough or sharp objects is mostly absorbed by the skin before it can damage the underlying tissues

A

Protection

recessive genetic trait that causes a deficiency or an absence of melain
- fair skin, white hair, unpigmented irises in the eyes

A

62
Q

Decrease in the blood o2 content produces a bluish color of the skin

A

Cyanosis

63
Q

yellowish skin color
- liver is damaged by a disease such as viral hepatitis

A

Jaundice

64
Q
  • injury to a tissue caused by heat, cold, friction, chemicals, elextricity, or radiation
A

Burn

65
Q
  • part of the stratum basale remains viable, regeneration of the epidermis occurs from within the burn area, as well as from the edges of the burn
A

Partial-thickness burns

66
Q
  • only the epidermis are red and painful
  • slight edema or swelling may be present
  • caused by sunburn or brief exposure to very hot or very cold objects
  • heal without scarring in about a week
A

first-degree burns

67
Q
  • damages both the epidermis and the dermis
  • If dermal damage is minimal – redness, pain, edema, and blisters
  • Healing = 2 weeks, no scarring results
  • If the burn goes deep into the dermis – wound appears red, tan, or white
  • Heal = take several months
  • Might scar
  • Epidermis, including the stratum basale where stem cells are found, is damaged
A

Second-degree burns
