stratum corneum
a fibrous protein that is also the principal component of hair and nails
keratin
the spiny layer just about the stratum germinativum. the spiny layer where the process of skin cell shedding begins
stratum spinosum
more commonly known as the basal cell layer, is the deepest layer of the epidermis
stratum germinativum
the basal cell layer also contains special cells called ___________, which produces the dark skin pigment called melanin
melanocytes
also known as derma, corium, cutis or true skin, is the underlying or inner layer of the skin
dermis
the highly sensitive ______ layer of connective tissue is about 25 times thicker than the epidermis

are the small involuntary muscles in the base of the hair follicle that cause goose bumps and papillae
Arrector Pili muscles
the outer most layer of the dermis, directly beneath the epidermis.
papillary layer
small, cone shaped elevations at the base of the hair follicles
dermal papillae
where is the dermal papillae locates
within the papillary layer
top of the papillary layer where it joins the epidermis is called the
epidermal-dermal junction
the deeper layer of the dermis that supplies the skin with all of its oxygen and nutrients
reticular layer
also known as adipose tissue or subcutis tissue, is the fatty tissue found below the dermis
subcutaneous tissue
