Skin-Brain Connection
- Skin and brain are deeply linked, with visible signs like blushing and goosebumps reflecting that connection.
- Touch sends information through ~600,000 nerve endings that detect pressure, vibration, and temperature.
Skin Is A Major Organ
- The skin is the body's heaviest organ, weighing about 11 pounds and composed of three layers.
- Each layer—hypodermis, dermis, epidermis—has distinct roles from energy storage to protection and sensation.
Layers Explain Skin Functions
- The hypodermis stores energy and vitamin D reserves while the dermis supports renewal and the epidermis acts as a protective barrier.
- This layered structure enables temperature sensing and regulation like sweating.
