HAP: Intugumentary quiz Flashcards
Type of tissue that makes up the epidermis
stratified squamous epithelium
The stem cells that give rise to new skin are from
stratum basale
Pacinian lamellated corpuscle
deep pressure mechanoreceptor
Ruffini corpuscle
mechanoreceptor found in skin near fingernails, detect pressure for grasping
Meisner corpuscle
Light touch mechanoreceptor found in dermal papillae
Kraus end bulb
cold thermoreceptor
Merkel disks
Mechanoreceptor found in stratum basale, pressure receptor
Nociceptors- free nerve endings
pain receptors
the structures of the skin that contribute to regulating and maintaining body temperature
arrector pili muscle- causes hair to stand erect (goosebumps)
sweat glands- cools down body
Hair- warmth
dermis blood vessels- controls blood flow (heat)
Dermis is made up of
loose areolar connective tissue
dense irregular connective tissue
characteristics of the dermal papillae
- 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
The sweat gland that has a pore directly to the skin surface is
merocrine
What are melanocytes
Melanin producing cells in the stratum basale
all functions of melanin
- Forms a cap over nucleus protecting DNA from UV damage
- protects folate from UV light
ultraviolet (UV) light
- causes mutations in DNA resulting in skin cancers
- stimulates melanin production
- stimulated vitamin D3 synthesis
Having dark skin is an evolutionary advantage (contributes to surviving to successful reproduction) because
dark skin protects folate from degrading in the blood
Darker skin increases the odds of surviving to reproductive age by protecting against skin cancer
False, does not increase odds
1st degree
- affects only superficial cells of epidermis
- red, inflamed and tender
2nd degree
- red, inflamed, painful and blisters
- affects superficial and deeper cells of the epidermis but not stratum basale
3rd degree
- destroys entire epidermis and into the dermis
- charred, destroyed stem cells, no sensation
necessary treatments for critical burns
- fluid resuscitation
- antibiotics
- skin grafts
autoimmune disorder resulting in loss of pigment protein
Vitiligo
skin cancer appears as a waxy bulb on surface
Basal cell carcinoma
mutation in gene encoding the body’s pigment protein
albinism
cancer that appears red and scaly, with an irregular appearance.
squamous cell carcinoma
metatasized cancer of cells producing skin’s pigment
malignant melanoma
Malignant melanoma is the most life threatening form of skin cancer
true
Treatments for malignant melanoma
- Interferon and Interleukin 2
- surgical removal
- chemotherapy
The first step in the process of wound healing is
Hemostasis
What are the stages of wound healing in order
Inflammation, proliferative, remodeling
