Skin is the body’s largest organ
Receptors of Skin
| Receptors | Specific roles | |
| 1 | Meissner receptors | Light touch |
| 2 | Pacinian corpuscles | Deep pressure and vibrational changes |
| 3 | Ruffini endings | Deep pressure and stretching of the skin’s collagen fibers. |
| 4 | Free nerve endings | Pain, light touch, and temperature variations. |
| 5 | Merkel receptors associated with the Merkel cells | Sustained light touch induction over the skin. |
Layers of Dermis
Dermis is divided into two layers, the papillary dermis (the upper layer) and the reticular dermis (the lower layer).
