Answer 3

stratum basale

Question 5

Pacinian lamellated corpuscle

Answer 5

deep pressure mechanoreceptor

Question 6

Ruffini corpuscle

Answer 6

mechanoreceptor found in skin near fingernails, detect pressure for grasping

Question 7

Meisner corpuscle

Answer 7

Light touch mechanoreceptor found in dermal papillae

Question 8

Answer 8

cold thermoreceptor

Question 9

Merkel disks

Answer 9

Mechanoreceptor found in stratum basale, pressure receptor

Question 10

Nociceptors- free nerve endings

Answer 10

pain receptors

Question 11

the structures of the skin that contribute to regulating and maintaining body temperature

Answer 11

arrector pili muscle- causes hair to stand erect (goosebumps)
sweat glands- cools down body
Hair- warmth
dermis blood vessels- controls blood flow (heat)

Question 12

Dermis is made up of

Answer 12

loose areolar connective tissue
dense irregular connective tissue

Question 13

characteristics of the dermal papillae

Answer 13

• increase surface area for diffusion of oxygen and nutrients into the stratum basale layer
• push up epidermis creating friction ridges on fingertips
• found within the papillary layer of the dermis

Question 14

The sweat gland that has a pore directly to the skin surface is

Answer 14

merocrine

Question 15

What are melanocytes

Answer 15

Melanin producing cells in the stratum basale

Question 16

all functions of melanin

Answer 16

• Forms a cap over nucleus protecting DNA from UV damage
• protects folate from UV light

Question 17

ultraviolet (UV) light

Answer 17

• causes mutations in DNA resulting in skin cancers
• stimulates melanin production
• stimulated vitamin D3 synthesis

Question 18

Having dark skin is an evolutionary advantage (contributes to surviving to successful reproduction) because

Answer 18

dark skin protects folate from degrading in the blood

Question 19

Darker skin increases the odds of surviving to reproductive age by protecting against skin cancer

Answer 19

False, does not increase odds

Question 21

2nd degree

Answer 21

• red, inflamed, painful and blisters
• affects superficial and deeper cells of the epidermis but not stratum basale

Question 22

3rd degree

Answer 22

• destroys entire epidermis and into the dermis
• charred, destroyed stem cells, no sensation

Question 23

necessary treatments for critical burns

Answer 23

• fluid resuscitation
• antibiotics
• skin grafts

Question 24

autoimmune disorder resulting in loss of pigment protein

Answer 24

Vitiligo

Question 25

skin cancer appears as a waxy bulb on surface

Answer 25

Basal cell carcinoma

Question 26

mutation in gene encoding the body’s pigment protein

Answer 26

albinism

Question 27

cancer that appears red and scaly, with an irregular appearance.

Answer 27

squamous cell carcinoma

Question 28

metatasized cancer of cells producing skin’s pigment

Answer 28

malignant melanoma

Question 29

Malignant melanoma is the most life threatening form of skin cancer

Answer 29

true

Question 30
