Regions Of The Skin Flashcards
The outermost layer and a vascular a keratinized stratified squamous epithelium consisting a four distinct cell type and five ways
Epidermis
Produce keratin a tough fibrous protein that gives the epidermis its durability and protection capabilities
Keratinocytes
Cells in this layer are dead there are flattened scale like remnants are full of keratin
Stratum corneum
Is translucent band of flattened and keratinocytes
Stratum lucidum
Contain waterproofing glycloped that is secreted into the extracellular space
Stratum granulosum
Between the epidermis and subcutaneous tissue
Dermis
Compose of loose areolar connective tissue
Stratum papillare
Lies under the papillary region and is usually much thicker.
Stratum reticulare
Protein fibers that give the dermis its properties of strength, extensibility, and elasticity
Stratum reticulare
Neverending sensitive for light touch
Meissnerβs corpuscle
Mechanoreceptors found in the skin and mucosa of vertebrates that provide touch information to the brain
Merkelβs disc
Nerve and things in the skin responsible for sensitivity to vibration and deep pressure
Pacinian corpuscle
Mechanoreceptor responsible for sensing position of hair
Hair follicle receptor
Sensitive to skin stretch and contributes the kinesthetic sense of and control of finger position and movement
Rufiniβs corpuscle
The lower most layer of the integumentary system invertebrates
Hypodermis
