Study Notes
Dermis
- The papillary layer of the dermis is responsible for discriminative touch
- The reticular layer of the dermis is composed of dense irregular connective tissue
Dermis Sensory Receptors
- Free nerve endings detect pain, temperature, and itching in the dermis
Epidermis-Dermis Interface
- Epidermal pegs/ridges in the dermis increase surface area for strong anchor points between the epidermis and dermis
Hypodermis
- The main function of the hypodermis is to attach the skin to underlying tissues and organs
- Pacinian corpuscles, a type of sensory receptor, respond to vibration in the hypodermis
