Study Notes
Skin Structure and Sensory Functions
- Krause End Bulbs: Specialized sensory receptors that sense touch and pressure within the skin.
- Epidermis: The outermost layer, serves as a waterproof barrier protecting deeper tissues from external factors.
- Dermis: Located beneath the epidermis, containing hair follicles, sweat glands, and providing structural strength and flexibility to the skin.
- Hypodermis: Composed mainly of adipose (fat) tissue, this layer acts as insulation, helping to regulate body temperature.
- Ruffini Endings: Mechanoreceptors that are sensitive to skin stretching, aiding in the perception of tension and the sense of movement.
- Fat (Adipose) Tissue: Functions primarily as an insulating layer, minimizing heat loss and contributing to energy storage.
- Meissner Corpuscles: Specialized nerve endings that detect light, superficial touch, playing a critical role in tactile sensitivity.
- Pacinian Corpuscles: These receptors respond to vibration, detecting rapid changes in pressure on the skin's surface.
