Assessment of the Skin, Hair, and Nails Flashcards
The largest organ of the body; ‘cutaneous membrane’
Skin
The focus on the Skin
Structure and Function
Physical barrier that protects from the underlying tissues and organs from microorganisms, physical trauma, ultraviolet radiation, and dehydration
Skin
Plays a vital role in temperature maintenance, fluid and electrolyte balance, absorption, excretion, sensation, immunity, vitamin D synthesis, and individual identity
Skin
Three Layers of the Skin
Epidermis
Dermis
Subcutaneous Tissue
Outer layer of the Skin / Consists of dead keratinized cells that render the skin waterproof
Epidermis
Five Layers of the Epidermis
Stratum Corneum
Stratum Lucidum
Stratum Spinosum
Stratum Granulosum
Stratum Germinativum
Keratin
Keratinocytes
Melanin
Melanocytes
Determinants of the Skin
Melanin
Capillary Blood Flow
Chromophores
Collagen
Inner layer of the Skin / Creates unique pattern of friction in hands and feet
Dermis
Two Layers of the Dermis
True Dermis
Dermal Papillae
Friction ridges
Fingerprints
Immune Response
Langerhans Cells
Sensory Response
Merkel Cells
Pressure / Vibration
Pacinian Corpuscles
Inflammation / Itch-Bound
Bradykinin
Components of the Skin
Collagen
Elastic Fibers
Nerve Endings
Lymph Vessels
Secretes an oily substance
Sebaceous Glands
Secretes across all sweat
Sweat Glands
Sweat and thermoregulator
Eccrine Glands
Milky sweat odor
Apocrine Glands
Stores fat / Provides insulation / Contains pathways
Subcutaneous Tissue
The formation of layered keratinized cells
Hair
The focus on the Hair
Structure and Function
Found over much of the whole body
Hair
Develops within a sheath of epidermal cells
Hair Follicle
At the base of the Hair Follicle
Hair Growth
Along dermal blood vessels
Hair Bulb
Visible above the Skin
Hair Shaft
Is surrounded by the Hair Follicle
Hair Root
Types of Hair
Lanugo Hair
Vellus Hair / Peach Fuzz
Terminal Hair / Permanent
Given featured hair
Lanugo Hair
Short, pale, fine, and present much over the body / Initiates Puberty
Vellus Hair / Peach Fuzz
Longer, generally darker, and coarser / Thermoregulation provider
Terminal Hair / Permanent
Yellow to Red pigmentation
Pheomelanin
Brown to Black pigmentation
Eumelanin
Tyrosinase
Graying
The transparent plates of keratinized cells
Nails
The focus on the Nails
Structure and Function
Formed fundamental packed plates
Nails
Grows out across
Cuticle
Extends over
Nail Body
Crescent-given area
Lunula
Blue pigmentation
Cyanosis
Yellow pigmentation
Jaundice
The leaning towards rendered health significance
Biological and Cultural Behavior Variations
More functioning Eccrine glands
Tropical
Less functioning Eccrine glands
Non-Tropical
Fewer functioning Apocrine glands
Asians
Less functioning Apocrine glands
Americans
Highest risk for Skin issues
Fair-Skinned
Later risk for Skin issues
