four major functions of the skin

1. protects body from physical damage, UV rays, and pathogens

2. maintains body temperature

3. excretes waste in the form of sweat

   1. perceives stimuli using nerves

epidermis

outermost layer of the skin

melanocyte

cells that produce dark pigmentf

functions of melanocytes

1. produces dark pigment

2. protects skin from UV rays

sebum

oil that lubricates hair and skin

collagen

connective tissue in skin; from Greek for “glue”

hypodermis/subcutaneous layer

layer containing fat cells

lunula

path/o

disease

-dermis

skin

-ectomy

difference between impetigo and tinea

impetigo is caused by bacteria while tinea is caused by fungus

petechiae

pinpoint round spots under skin (medical side effect)

varicose veins

veins that lose elasticity and appear twisting

difference between a keloid and wart

keloids caused by overgrowth of scar tissue; warts caused by virus (HPV)

visual difference between psoriasis and eczema

psoriasis has silvery patches; eczema does not

scleroderma

chronic autoimmune condition causing connective tissue hardening

urticaria

hives

two conditions caused by poor blood circulation

gangrene and cyanosis

difference between first- and second-degree burns

second-degree burns include blisters

difference between second- and third-degree burns

third-degree burns include severe numbness

two things that clinicians evaluate in burn patients

1. severity of burn

2. percentage of body affected (TBSA)

percentage of total body surface area for both the anterior and posterior of the head

9 percent

vesicle

small, raised skin lesion filled with clear fluid

fissure

crack or groove (as in a sore)

wheal

smooth, slightly swollen area redder or paler than surrounding skin

ulcer

open sore or erosion of the skin

papule

solid skin elevation with distinct borders

pustule

small, infected skin elevation that contains pus

cyst

closed, thick-walled sac containing fluid

macule

small, flat, discolored lesion

nodule

skin elevation larger than 1 centimeter

nevus

highly pigmented lesion

three elements the skin protects the body from

1. physical damage

2. UV rays

3. pathogens

skin helps regulate temperature by…

sweating to cool down the body

purpose of tactile receptors

to perceive/sense touch

location of mucous membranes

nasal cavity, intestines, and any cavity opening to the outside

stratified

arranged in layers

squamous

scaly

three characteristics connective tissue provides

1. shape

2. strength

3. elasticity

major difference between sebaceous and sudoriferous glands

sebaceous = oil/sebum; sudoriferous = water/sweat

areas of body with greatest number of sweat glands

palms of hands, soles of feet

cause of sweat body odor

bacteria interaction/reproduction

who has more hair follicles on average: redheads or blondes?

blondes

arrector pilli

tiny muscle in skin; causes hair to “stand on end”

keratin

substance that makes up nails

why do clinicians examine nails?

first signs of disorders can appear on nails
