The Integument Matching
melanocyte
cell found in the epidermis that produces a dark pigment
stratum corneum
outermost layer of the epidermis
melanin
a dark pigment produced by melanocytes that protects the skin from ultraviolet radiation
stratum basale
a layer made of a single row of actively dividing keratinocytes
Langerhans cell
a macrophage found in the dermis
fibroblast
cellular component of the dermis the manufactures fibers and ground substance
reticular layer
deeper layer of the dermis that consists of dense, irregular connective tissue
stratum granulosum
epidermal layer that consists of multiple rows of keratinocytes that are beginning to fill with keratin and the nuclei are degenerating
stratum spinosum
epidermal layer that still shows some cell division and contains a large number of Langerhans cells
Merkel cell
found in the basal layer of the epidermis and associated with sensory nerve endings
eccrine sweat gland
gland that secretes sweat directly onto the surface of the epidermis via a duct
hair follicle
invagination of the epidermis in which a hair is anchored
keratinocyte
keratin-producing cell
stratum lucidum
layer found only in thick skin consisting of a few rows of flattened dead cells
adipocyte
main cell of the hypodermis and is filled with fat
dermis
makes up the greatest portion of the skin and is responsible for the structural strength of the skin
sebaceous gland
sebum-producing gland that secretes directly into the hair follicle
arrector pili muscle
small muscle attached to each hair follicle
epidermis
the outermost layer of the skin
hypodermis
thick layer of the integument made of loose areolar connective tissue rich with adipose tissue
pacinian corpuscle
touch receptor in the hypodermic that is sensitive to heavy pressure
Meissner's corpuscle
touch receptor in the hypodermic that is sensitive to light touch
papillary layer
uppermost, thin superficial layer of the dermis
dermal papilla
upward projections of the dermis that interdigitate with the epidermis to hold the layers together
