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
