Peel through the layers of the body's largest organ in 3D — epidermis, dermis, hypodermis, and hair follicle with labeled hotspots by Aurelia RMT.
Labeled Hotspots
Epidermis — Outermost avascular layer; stratified squamous epithelium; five sub-layers (stratum basale, spinosum, granulosum, lucidum, corneum); contains keratinocytes, melanocytes, and Langerhans cells; renews every 2–4 weeks
Dermis — Vascular connective tissue beneath the epidermis; papillary (loose) and reticular (dense) layers; contains collagen and elastin fibers, blood vessels, lymphatics, nerve endings, sweat glands, and sebaceous glands; provides tensile strength and elasticity
Hypodermis (Subcutaneous Layer) — Deepest layer; adipose and loose connective tissue; insulation, energy storage, and anchoring the skin to underlying fascia and muscle
Hair Follicle — Invagination of epidermis into the dermis; produces the hair shaft; associated with sebaceous gland and arrector pili muscle; growth cycles through anagen, catagen, and telogen phases
