Integumentary System (Cancer: (Dermis: connective…

- - - - Cutaneous membrane (skin):
        *Located in major organs of integumentary system, covers body surface.
        
        Made of keratinized stratisfied squamous epithelium under which is the dense connective.
        
        Mucous membrane:
        
        Located in the line cavities that open exterior.
        
        Layer of epithelium over loose connective; epithelium varies with location.
        
        Serous membrane:
        *Located in cavity linings & cover organs close to nth exterior.
        
        Simple squamous epithelium over loose connective tissues.
- - - - Stratum Granulsom:
        
        3/5 layers of keratinocytes
        
        kerattinization begins to occur
        
        cells start to die.
        
        Stratum spimosum:
        *several layers thick
        
        keratinocytes build the stratum basal
        
        spiny appearance
        
        Stratum Basale:
        deepest layer seperated dermis from epidermis
        *attatched to the basesment membrane
        
        stem cells produce new epithelial cells.
        
        oldest cells are along th top
        
        new cells are on the bottom.
- - - - Melanin: Primary pigment
        
        Carotene: Yellow pigment
        
        Hemoglobin: red color from blood
