T1 - Skin Assessment (Josh) Flashcards
What is the largest organ of the body?
skin
The skin is a site of metabolic activity. What does it do?
activates Vitamin D
Which layer of skin is the site of Vit D activation?
epidermis
***doesn’t have own blood supply
What is the main component of dermal tissue?
collagen
Which layer of skin contains capillaries, lymph vessels, and sensory nerves?
dermis
What are the pigment-producing cells of the skin called?
melanocytes
What are the 3 layers of skin?
Epidermis (outer)
Dermis (middle)
Subcutaneous (inner)
What are the 3 layers of the Epidermis?
Stratum Coreum (outer)
Stratum Granulosum (middle)
Basal Layer (inner)
What is the time frame for epidermis regeneration?
28-45 days
Which layer of skin is made up of fat, smooth and areolar tissue?
What is purpose of this layer?
Subq layer
- heat insulator
- shock absorber
- nutritional deposits
What are the main 2 components of the dermis?
Collage
Elastic Fibers
Dermis:
Collagen is produced by — cells
fibroblast
What all is contained in the Dermis?
Blood Vessels
Sweat and Sebaceaous Glands
Hair Follicles
Nerves to skin
Sensory fibers
Capillaries
Mast Cells (secretion, phagocytosis, production of fibroblasts)
Which layer of skin contains the Mast Cells?
Dermis
Name this skin layer:
- Vitamin D is regulated
- Temperature regulation
- Transmits sensations
- Homeostasis
Epidermis
Skin Cells:
— provide skin color
— help regenerate skin
melanocyts
keratinocytes
Nail Anatomy:
Where is keratin produced and new growth of a nail begins?
Lunula (white part of cuticle)
What is purpose of sebaceous glands?
sebum provides lubrication and waterproofing of skin
What are the 2 types of Sweat Glands?
Eccrine (over entire skin surface)
Apocrine (axillae, nipple areolae, periumbilicus, perineal areas)
***causes odor
What are some health problems we should assess for that can cause skin damage?
Liver problems (jaundice)
Kidney problems
Diabetes
COPD
What is the the rubric for assessing skin lesions (moles)?
ABCDE
A - assymetry of shape B - border irregularity C - color variation within one lesion D - diameter greater than 6 mm E - evolving or changin features
When we inspect skin, what signs are we looking for?
Edema
Moisture
Vascular Changes
What are some age-related changes we should look for in skin assessment?
Senile (cherry) agniomas
Xerosis
Wrinkles (due to less collagen)
Paper-thin, transparent skin (due to less subq tissue)
Actinic Lentigo (liver spots)
What is Petechiae a sign of?
increased capillary fragility and venous stasis
