Keeping you warm
What are three epithelial membranes
Serous
Mucous
Cutaneous
Where can you find mucous membranes
Nasal, trachea or the stomach
What is visceral serosa
Attached to the organ (inner)
What is the perietal serosa
Attaches to the body cavity
Where is the serous fluid
In between visceral and perietal
Another name for cutaneous membrane is
Epidermis (skin)
What kind of cells make up the epidermis?
Stratified squamous
What is the epidermis
Top layer of skin
What systems can you find mucous membranes

What kind of cell type and tissue makes up serous membrane
Simple squamous
Areolar
What are 2 cells of epidermis
Keratinocytes
Melanocytes
What are keratinocytes
Cells that move from deeper in the skin to the skins surface.
When the skin cells are at the skin surface and dying, what are they called?
Keratin
What is keratin?
Tough proteins that make the epidermis a great physical barrier
What are the layers of the epidermis?
Stratum Basal
Stratum spinosm
Stratum granulosum
Stratum Lucidum
Stratum corneum
Which layer of the epidermis can only be found in thick skin
Stratum lucidum
What is the acronym for the layers of the skin?
Boys see girls like crazy
Where can you find the stratum basal
Deepest layer
Where can you find stratum spinosm
Above basal layer
What is the main function of the spinosm layer
Resist pulling when skin is stretching and produces pre-keratin
What’s granulosum main function
Create a waterproof barrier to retain fluid
Which dermal layer is easiest to spot
Granulosum
What is the main function of stratum lucidum
Protects from abrasion
Where can you find corneum
Top layer of epidermis largest layer
What is under the epidermis
Dermis
What are the three layers of the dermis?
Dermal papillae
Papillary layer

What is the main function of the papillary layer
To provide nutrients to epidermis
What does the papillary layer look like?
Ridges and swirls
What kind of tissue is dermal papillae
Areolar Loose connective tissue
What does dermal papillae look like
Peg or nipple like structures
Where can you find the reticular layer?
Under the papillary layer and dermal papillae
What kind of tissue is the reticular layer?
Dense, irregular tissue
