A fat cell is a/an
adipocyte
The half-moon–shaped white area at the base of a nail is the
lunula
A structural protein found in skin and connective tissue is
collagen

The deepest region of the epidermis is the
basal layer
The outermost layer of the epidermis, which consists of flattened, keratinized cells, is the
stratum corneum
An oily substance secreted by sebaceous glands is
sebum
The middle layer of the skin is the
dermis
A hard, protein material found in epidermis, hair, and nails is
keratin
A band of epidermis at the base and sides of the nail plate is the
cuticle
