The skin performs what functions
Protection , Excretion , temperature regulation ,
Sensory perception ,
Synthesis of vitamin D
Absorption
Describe the structures and functions of two tissue layers forming skin
Epidermis-is Keratinized stratified squamous epithelium layer
Dermis- the deep layer of the skin can be divided into two region papillary layer,
Dermal papillae
Dermis contains
Papillary layer recticular layer
List six functions of the skin
Absorption, protection, excretion, temperature regulation, sensory perception, synthesis of vitamin D
Contains adipose tissue
Subcutaneous tissue
Deep layer of the epidermis
Stratum Basle
Composed of stratified squamous epithelial
Epidermis
Skin layer lacking blood vessels
Epidermis
Superficial layer of the epidermis
Stratum Corneum
Composed primarily of keratinocytes
Epidermis
Forms new epidermal cells
Stratum Basel
Formed of dead Keratinized cells
Epidermis
Provides insulation to the body
Subcutaneous tissue,
Provides strength and elasticity of skin
Dermis
Deep layer of skin
Subcutaneous tissue
Superficial cells are continuously sloughed off
Stratum corneum
Formed of areolar and dense irregular connective tissues
Dermis
Three pigments that determine skin color
Hemoglobin, carotenes, melanin
Protects from UV rays
Melanin
Cells producing melanin productions
Melanocytes
Increase melanin production
Radiation, UV rays
