The Dermis of Skin
dermal papillae
peglike projections of the superior papillary layer which indent the overlying epidermis
pacinian corpuscles
pressure receptors w/in the reticular layer of the dermis
apocrine glands
suderiferous glands which secrete a milky, fat-rich substance
exocrine
suderiferous/sweat glands are this type of gland
fibroblasts, adipose, macrophages
type of cells found w/in the dermis
dense irregular CT
type of tissue which forms the reticular layer of the dermis
reticular layer
accounts for 80% of dermis thickness
blackhead
accumulation of dried sebum, bacteria and melanin from epithelial cells in the oil duct
acne
active infection of the sebaceous gland
merocrine sweat glands
an alternative name for eccrine glands
apocrine glands
analogous to pheremone-producing scent glands of other animals
axillary and genital areas
areas in which apocrine glands are predominatly found
goosebumps
contraction of the arrector pili results in this phenomenon
reticular layer
dermis layer deep to the papillary layer
heat-regulation
eccrine glands aid in this homeostatic process
papillary layer
made of areolar CT; collagen and elastin fibers form loosely woven mat
sebum
mixture of oily substances and fragmented cells which acts as lubricant and moistener of skin
sebaceous glands
oil producing glands
meissner's corpuscles
pain and touch receptors residing in the papillary layer
reticular layer of dermis
site of sweat/sebaceous glands and pressure receptors
arrector pili
small band of smooth muscle which connects each hair follicle to the papillary layer of the dermis
dermal papillae
structures of dermis responsibe for fingerprints
suderiferous glands
sweat glands
eccrine glands
sweat glands distributed all over the body
papillary layer
the superficial layer of the dermis
palms and soles of feet
the two places you won't find sebaceous glands
