Anatomy Physiology Epidermis Glands Cells
10
What is the hypodermis?
The component that connects to the skin and serves as a storage repository for fat.
10
What is a water barrier ?
Keratin and oils in the skin reduce water loss through evaporation and form a barrier against water infusion.
10
What is stratum granulosum?
The layer of somewhat flatten cells just superficial to stratum spinosum and inferior to the stratum lucidum.
10
What is the eccrine glands?
The glands that empty directly into the skin.
10
What are Merkel cells?
The cells of the epidermis that function as touch receptors.
20
What is the papillary layer?
Fingerprints are derived from patterns here.
20
What is temperature regulation?
Capillaries dilate to dissipate heat and constrict to conserve heat. Sweat evaporation provides a cooling effect.
20
What is stratum spinosum?
The layer of the epidermis superior to stratum basale and inferior to stratum granulosum.
20
What is sebaceous glands?
Produces a substance called sebum.
20
What is lipocytes?
The hypodermis is the location for these fat cells.
30
What is arrector pili?
These tiny muscles cause “goose-bumps” when we are cold or frightened.
30
What is vitamin d production?
Sunlight converts modified cholesterol molecules to vitamin D, which is essential for bone health.
30
What is stratum basale?
The innermost layer that absorbs nutrients from the dermis.
30
What is chemical reaction caused by bacteria ?
The unpleasant odor when a person sweats.
30
What is melanocytes?
These specialized cells responsible for skin color.
40
What is keratin?
The tough protein that strengthens hair and nails.
40
What is waste elimination?
Urea and uric acid are eliminated in sweat.
40
What is stratum corneum?
The layer of the epidermis that consists of dead cells filled with keratin.
40
What is apocrine and eccrine glands?
The two types of sudoriferous glands.
40
What is keratinocytes?
Cells within the epidermis that produce keratin.
50
What is the reticular layer?
The layer of the dermis that contains blood vessels sweat and oil glands, involuntary muscles, hair follicles and nerve endings.
50
What is sensory perception?
Receptor cells transmit information about touch, pressure, vibration, pain, and temperature to the central nervous system.
50
What is stratum lucidium?
The clear layer of thick skin found on the palms of the hands, fingers, soles of the feet and toes.
50
What is sweat?
A chemical waste product that includes urea, uric acid, and salts that protects against bacteria.
50
What is melanocytes?
The cells in individuals with albinism do not produce melanin.
