deeper and much thicker region, composed mainly of dense, irregular connective tissue whose collagen fibers provide the skin with strength and whose elastic fibers provide elasticity
arrector pili
bundle of smooth muscle cells attached to the connective tissue sheath around the hair follicle (causes "goosebumps")
Centrioles
Form mitotic spindle; needed to form cilia and flagella
Epidermis
keratinized stratified squamous epithelium
Cartilage
extracellular matrix consists of collagen and elastic fibers embedded in a firm gelatinous ground substance/Collagen fibers give the tissue strength, & the ground substance, binds water to form a firm gel, gives cartilage its resiliency
Ribosomes
Site of Protein Sythesis
Peroxisomes
Produce hydrogen peroxide and detoxify harmful substances
Flagella
Long cell projection whip-like motion moves sperm
Cilia
hair-like cell projections that move fluids and particles
Papillary Region
deep to the stratum basale of the epidermis and the basement membrane, finger like projections that extend into the epidermis (causes fingerprints)
