In hairy skin, Merkel nerve endings are clustered into specialized epithelial structures called "touch domes" or "hair disks". Merkel receptors are also located in the mammary glands. Wherever they are found, the epithelium is arranged to optimize the transfer of pressure to the ending. [citation needed]
Merkel cell. Merkel cells are found in the skin and some parts of the mucosa of all vertebrates. In mammalian skin, they are clear cells found in the stratum basale [2] [3] (at the bottom of sweat duct ridges) of the epidermis approximately 10 μm in diameter. They are oval-shaped mechanoreceptors essential for light touch sensation and found ...
The Pacinian corpuscles are located within the deeper layer of the skin, under the skin in the subcutaneous tissues, within muscles, in the periosteum, and other deeper layers of the body. The Merkel disk receptors are located in the superficial epidermis and in hair follicles, while tactile corpuscles are concentrated heavily in the fingertips ...

The Slowly Adapting type 1 (SA1) mechanoreceptor, with the Merkel corpuscle end-organ (also known as Merkel discs) detect sustained pressure and underlies the perception of form and roughness on the skin. [1] They have small receptive fields and produce sustained responses to static stimulation. [citation needed]
Distant (the cancer has spread to the lungs, liver, or distant parts of the body): 24% Overall, the ACS noyrd that the survival rates for Merkel cell carcinoma in all stages is 65%.
Merkel's Disks - Located on the upper part of the dermis. Slow adapting receptors. Found on the fingertips as well as the eyelids. Meissner's Corpuscles - Located also on the upper part of the dermis. Found on the hairless skin including the lips as well as the eyelids. These are rapid adapting receptors.
The skin cancer that killed Jimmy Buffett is rare. About 2,000 cases of Merkel cell carcinoma are diagnosed each year in the U.S.
