Cutaneous Sensory Receptors are clustered in certain spots instead of being uniformly distributed. This clustering is called punctate distribution.

Sensory receptors in skin?
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.]
Are cold or heat receptors more numerous?
More cool receptors than warm receptors in the skin.
The two types of receptors that bind acetylcholine are?
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.
What layer of skin contains sensory receptors for touch?
The Dermis layer contains the sensory nerve fiber, so it is the Dermis layer that contains sensory receptors for touch.
Chemoreceptors that detect odors are called what?
olfactory receptors
Specialized nerve endings that respond to temperature touch etc?
Thermoreceptors
What is punctuate distribution?
The uneven clustering of receptors in order to provide sensitivity to body areas that need it most.
What are cutaneous glands?
similar to sensory receptors in the body, they recognize a change in stimulus
