vasoconstrict

in response to hot temperatures outside, dermal blood vessels __________

vasodilate

third degree

1. all of the dermis is affected 2. skin grafts may be required 3. sometimes muscle and bone are destroyed

thin skin

1. contains sebaceous glands 2. does not include the stratum lucidum 3. contains hair follicles 4. found over most of the body

merocrine

1. found distributed over entire body 2. thermoregulation 3. abundant in hands, feet., and forehead

apocrine

1. found mostly in the area of pubic, axillary, and beard hair 2. not active until puberty 3. scent is meant to attract a potential mate

thick skin

1. found on the palms of the hands 2. found on the soles of the feet 3. does not contain hair follicles 4. contains all five epidermal strata

vasoconstriction

1. going outside on a cold day 2. jumping into a cold pool

chemical signal dispersal

1. hairs disperse pheromones 2. pheromones are involved with attracting members of the opposite sex

melanoma

1. if metastasized, the deadliest skin cancer 2. arises from the cells that protect from UV light 3. the least common skin cancer 4. caused by mutations commonly found in moles

temperature regulation

1. if the body becomes too hot, the dermis of the skin contains a large number of blood vessels that increase in size to allow for increased heat loss 2. if the body becomes too hot, sweat glands release their contents to help control and/or cool our internal temperature
