Lesson 3.2 Flashcards
apocrine glands
sweat glands located in the genital areas that secrete a milky fluid consisting of sweat, fatty acids, and protein.
dermis
layer of skin between the epidermis and hypodermis includes nerve endings glands and hair follicles
eccrine glands
sweat glands located over the majority of the body that produces a clear acidic fluid that consists of 99% of water but also contains waste products such as urea, uric acid etc.
epidermal dendritic cells
skin cells that initiate an immune system response to the presence of foreign bacteria or viruses.
epidermis
the outer layer of skin
hypodermis
the layer of tissue beneath the dermis which serves as a storage repository for fat.
integumentary system
enveloping organ of the body that includes the epidermis dermis, sudoriferous and sebaceous glands and nails and hair.
keratin
tough protein found in the skin hair and nails
keratinocytes
cells within the epidermis that produce keratin
lipocytes
fat cells
melanin
a pigment that protects the body against the harmful affects of ultraviolet damage from the sun.
melanocytes
specialized cells in the skin that produce melanin
merkel cells
touch receptors in the skin
papillary layer
the outer layer of the dermis
reticular layer
the layer of skin superficial to the to the papillary layer
sebaceous glands
glands located all over the body that produce sebum
sebum
an oily substance that helps to keep skin and hair soft
stratum basale
deepest layer of the epidermis
stratum corneum
the outer layer of the epidermis
stratum granulosum
a layer of somewhat flattened cells lying just superficial to the stratum spinosum and inferior to the stratum lucidum.
stratum lucidum
the clear layer of thick skin found only on the palms of hands, fingers, soles of feet, and then toes.
stratum spinosum
the layer of cells in the epidermis superior to the stratum basale and inferior to the stratum granulosum
subcutaneous fascia
the tissue that connects the skin to underlying structures the hypodermis
sudoiferous glands
sweat glands that are distributed in the dermis over the entire body.
