A cutaneous receptor is the receptor present in the skin.
The skin is a complex organ containing various sensory receptors that allow us to perceive touch, pressure, temperature, and pain. These receptors are collectively known as cutaneous receptors. These receptors are located in the dermis or epidermis of the skin. They play a crucial role in our interaction with the environment by providing sensory information to the central nervous system.
Here's a breakdown of cutaneous receptors and their function:
Types of Cutaneous Receptors:
| Receptor Type | Function | Location |
|---|---|---|
| Mechanoreceptors | Respond to mechanical stimuli (touch, pressure) | Epidermis and Dermis |
| Thermoreceptors | Respond to temperature changes | Epidermis and Dermis |
| Nociceptors | Respond to pain stimuli | Epidermis and Dermis |
- Mechanoreceptors: These are the most diverse group, and includes:
- Meissner's corpuscles: Light touch and texture
- Pacinian corpuscles: Deep pressure and vibrations
- Merkel's disks: Sustained light touch and pressure
- Ruffini endings: Skin stretch and sustained pressure
- Thermoreceptors: Respond to heat and cold, allowing us to detect changes in temperature.
- Nociceptors: These receptors are responsible for the sensation of pain. They are activated by potentially damaging stimuli, such as extreme temperatures, mechanical damage, or the presence of harmful chemicals.
In summary, the cutaneous receptor, located in the dermis or epidermis, is the general name for sensory receptors in the skin responsible for sensing touch, temperature and pain.
