Mechanoreceptors
When the hairs are stimulated, the "trap" closes.
Pain receptors are bare dendrites that react to a certain type of stimulus. Some pain receptors become activated when extremes of heat or cold cause your skin temperature to rise or fall to dangerous levels. Hope this helps!
Thermoreceptors
Nerve receptors are stimulated during urination. This stimulation occurs when the walls of the bladder contract and the urination reflex is automatically activated.

Sensory receptors.
Human hairs have touch receptors that wrap around their roots, so they help in tactile sensory reception.
Nociceptors are stimulated by tissue damage and are also called pain receptorsSourceIntroduction to the Human Bodyby Gerard Tortora and Bryan Derrickson
The sensory nerve endings are specialized neurones that are stimulated to fire action potntiels based on chemical factors, photons, heat etc depending on their location and type.

Cell surface receptors are stimulated by outside chemicals, such as hormones or neurotransmitters, which in turn trigger the cell to carry out specific functions. The binding of these chemicals to the receptors initiates a signaling cascade within the cell that leads to various cellular responses.
The process by which the brain causes a sensation to seem to come from the stimulated receptors is called sensory localization. This involves the brain integrating sensory information from different receptors to create a coherent perception of the world around us, including determining the location of the source of a sensation.
