Functions of Skin
- Provides protective membrane
- Skin glands lubricate and cool the skin
- Receptor for sensations
- Helps maintain body temperature
lubricate: lam tron, nhon
Functions of Skin (cont’d)
- Produces sweat: sweat glands produce a watery secretion that evaporates and cools
- Produces sebum: sebaceous glands produce an oily secretion that lubricates the skin and hair
- Receives sensation: pain, temperature, pressure, and touch
- Thermoregulates: interprets message from heat center in the brain
evaporates (v): lam bay hoi; sebum: dau nhon, sebaceous glands: tuyen ba nhon; Thermoregulate: dieu chinh nhiet
- Structure of the Skin
Epidermis: outermost, thin cellular membrane
Dermis: next layer; dense fibrous, connective tissue
Subcutaneous tissue (hypodermis): thick, fat-containing tissue
Epidermis: bieu bi, Dermis: ha bi, hypodermis: lop duoi da
Accessory Organs of the Skin 1
Hair: cells filled with the hard protein; keratin (chat sung)
- Hair follicles: shafts that hold the hair
- Five million hairs on the body; 100,000 on the head
- Melanocytes at the root form the color
- Grows .5 inch (1.3 cm) per month
- Cutting does not affect growth
Hair follicles: nang long, Melanocytes: the bao bier bi tao hac to.
Accessory Organs of Skin (cont’d) 2
Nails: hard keratin plates covering the toes and fingers
Lunula: vat hinh luoi liem
Cuticle: bieu bi
Paronychium: viem da mong ngon tay ngon chan
Accessory Organs of Skin (cont’d) 3
Glands: sebaceous and sweat
- Sebaceous glands secrete oily sebum into the hair follicle to lubricate.
- Sweat glands secrete into pores to moisten and cool.
- Both are subject to bacterial growth.
