Cell Type
Cube shaped cells
Cuboidal
Long filaments of dead keratinocytes
Hair
20-30 layers of dead, tightly bound cells
Stratum Corneum
What are the three ways the Integumentary system creates barriers to protect?
Physical, Chemical and Biological
Largest organ in the Human body
Skin
Elongated Cells
Columnar
The shape of this determines the texture of your hair
Hair follicle
the exterior epithelial tissue of the skin is called
Epidermis
Synthesizes this, which allows the body to absorb calcium
Vitamin D
skins immune cells
Dendritic or Langerhans Cells
Flat Cells
Squamous
Most abundant sweat gland
Eccrine Sweat Gland
Made of dense irregular connective tissue, houses blood vessels and collagen fibers for strength
Reticular dermis
this function gets rid of wastes
Excretion
Bottom layer of epidermis
Stratum basale
misshapen cells that create fake layers
pseudostratified
Muscle attached to the hair that contracts to stand up your hair
arrector pili
The majority of the integumentary system is made of this connective tissue layer
Dermis
sensory receptors
Produce melanin
melanocytes
dead cells that make up hair and outer layer of skin
Keratinocytes
Sweat gland that lies deeper in dermis and can be modified to produce ear wax, or breast milk.
Apocrine sweat glands
Layer of skin only found in "thick skin"
Stratum Lucidum
vasodilation and sweat are products of this function
Temperature regulation
Sensory receptors for touch in epidermis
Tactile or Merkel Cells
