Cutaneous Sensory Receptors are clustered in certain spots instead of being uniformly distributed. This clustering is called punctate distribution.
Your main sensors in the skin are those for some types of pain or touch. We can distinguish a sharp from a blunt touch, and a brushing with a wisp of cotton wool will elicit a different sensation again. Vibration is a separate touch sensation again, as is also the detection of heat and cold. Perhaps you could consider smell (olfaction) to be a skin sense, but here the smell is first dissolved in the mucus before detection. [I had a side effect of a drug, which numbed the sense of vibration - it was only felt as a blunt touch. The operand was a tuning fork, which produces a small vibration at the stem. The proper sensations returned after >12 months off the drug.]
More cool receptors than warm receptors in the skin.
nicotinic acetylcholine receptors (nAChR, also known as "ionotropic" acetylcholine receptors) are particularly responsive to nicotinemuscarinic acetylcholine receptors (mAChR, also known as "metabotropic" acetylcholine receptors) are particularly responsive to muscarine.Nicotinic and muscarinic are two main kinds of "cholinergic" receptors.
The Dermis layer contains the sensory nerve fiber, so it is the Dermis layer that contains sensory receptors for touch.

Thermoreceptors
Cutaneous sensory receptors in the skin are part of the somatosensory portion of the nervous system.
Simple Pain receptors.
Cutaneous glands are glands located in the skin that secrete substances such as sweat, oil, and wax. These glands help regulate body temperature, prevent dehydration, and protect the skin from external factors. There are two main types of cutaneous glands: sweat glands (eccrine and apocrine) and sebaceous glands.

Meissner's corpuscles
The somatosensory system is responsible for holding the cutaneous sensory receptors that reside in the skin. These receptors allow us to sense touch, pressure, temperature, and pain. The somatosensory system transmits these signals to the brain for processing.
Touch, temperature and pain.
Cutaneous receptors for pain are located primarily in the skin and subcutaneous tissue. They are particularly concentrated in the outermost layer of the skin, known as the epidermis, and in the underlying dermis. These receptors are responsible for detecting painful stimuli such as heat, pressure, or injury on the skin's surface.
