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
Test your knowledge of the dermis and its composition in this informative quiz. Discover the layers, tissue types, and sensory receptors found in this important part of the skin.
