This subcutaneous layer stores fat and has large blood vessels.
Hypodermis
Cells that participate in immune response
Langerhans cells
This tissue can be found covering body surfaces and lining hollow organs.
Epithelial tissue
Cares for abrasions and minor burns (first degree or less)
Superficial epidermal wound healing
Whiter area of the nail body, obscures vascular tissue underneath.
Lunula
This region of the dermis is responsible for fingerprints and footprints.
Papillary dermis
Produce melanin protein for protection from ultraviolet light
Melanocytes
Cellular organelles that synthesize proteins
Ribosomes
Two methods in which body temperature is regulated
Evaporation of sweat and blood flow regulation
Sensory nerve ending surrounding each hair follicle that is sensitive to the touch.
Hair root plexus
This layer of the skin contains no blood vessels.
Epidermis
Layer that contains keratinocytes, melanocytes, and Merkel cells
Stratum basale layer
Neurons convert stimuli into these electrical signals
Action potentials
Tactile sensations (touch, pressure, vibration) as well as thermal sensations (warmth, coolness)
Cutaneous sensations
Sudoriferous glands responsible for waste removal and temperature regulation. Releases during emotional stress.
Eccrine sweat glands
Location for collagen and elastic fibers that contribute to the elasticity and strength of the skin.
The reticular region of the dermis
Dead keratinocytes slough off this layer
Stratum corneum
Organelle that synthesizes fatty acids and steroids
Smooth endoplasmic reticulum
Phase of deep wound healing in which granulation tissue forms.
Migratory phase?
Location of blood vessels that nourish the hair follicle.
Papilla
One of the following does NOT contribute to skin color: Hemoglobin, melanin, keratin, carotene
Keratin
This layer is present only in the skin of the fingertips, palms, and soles
Stratum lucidum
The process of converting DNA into RNA
Transcription
Deep wound healing phase in which blood clots unite wound edges.
Inflammatory phase
Epidermal band overlapping the edge of the nail body.
Cuticle
