Which of the following cells act as touch receptors?
Merkel cells act as touch receptors.
- Merkel cells, also known as Merkel-Ranvier cells or tactile epithelial cells, are oval-shaped mechanoreceptors essential for light touch sensation and found in the skin of vertebrates.
- They are abundant in highly sensitive skin like that of the fingertips in humans and make synaptic contacts with somatosensory afferent nerve fibers.
- 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 (at the bottom of sweat duct ridges) of the epidermis approximately 10 μm in diameter.
