17
Q

hair follicle

A

stands of hair originate in an epidermal penetration of the dermis called the hair follicle- under skin and hair shaft

18
Q

hair shaft

A

is the part of the hair not anchored to the follicle and much of this is exposed at the skin’s surface- in the the epidermis and dermis

19
Q

hair root

A

ends deep in the dermis at the hair bulb and includes a layer of mitotically active basal cells- epidermis

20
Q

free edge

A

Protects the tips of our fingers and toes as they are the farthest extremities and the parts of the body that experience the maximum mechanical stress- beyond the nail plate

21
Q

lunula

A

thick layer of epithelium over the nail matrix forms a a crescent region- closest to the skin of the finger

22
Q

Epomychium

A

the nail fold that meets the proximal end of the nail body and forms the nail cuticle- on the vertical side of the proximal nail fold

23
Q

Nail Root

A

nail body forms at the nail root, which has a matrix of proliferating cells from the stratum Basale that enables the nail to grow- lies below the skin under the nail

24
Q

Pores

A

a minute opening in a surface, especially the skin or integument of an organism, through which gases, liquids, or microscopic particles can pass- located on the face, chest, back, groin; along the surface of the epidermis

25
Q

Apocrine Sweat Glands

A

is usually associated with hair follicles in densely hairy areas, such as armpits and genital regions- located in dermis

26
Q

Eccrine Sweat Glands

A

is a type of gland that produces a hypotonic sweat for thermoregulation- located in dermis

27

Q

first degree burns

A

  • red and painful, swelling
  • cool the burn and cover it with bandage
36
Q

2nd degree burn

A
  • outer and part of inner layer of skin (epidermis, dermis)
  • often looks wet
  • may be caused by hot water, open flames, hot objects, sun, chemicals, and electricity
  • blisters, pain, swelling, etc
37
Q

3rd degree burns

A
  • destroy epidermis and dermis
  • also damage bones, muscles, tendons
  • charred and no sensation in area b/c nerve endings destroyed
  • dark brown color, leathery
  • skin graft, IV fluid, etc
38
Q

4th degree burn

A
  • go through both layers of skin and underlying tissue as well as deeper tissue
  • flames, chemicals, etc
  • charred looking appearance, which in color, exposed bone and muscle tissue, etc
  • professional help to heal
39
Q

Stretch Marks

A
  • are a type of scar that develops when skin stretches or shrinks too quickly
  • streak lines on body
  • no treatment- topical maybe
40
Q

  • avoid repetitive actions that cause them
  • on feet and toes, hands
