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.

tiny hairs within the cochlea are stimulated by vibration. then neurons of the spiral ganglion are stimulated.
For example, nociceptors that extend from the skin are stimulated by sensations such as pressure, temperature, and chemical changes.
When beta receptors are stimulated, it decreases the heart rate to treat for low blood pressure.
sodium ions enter the postsynaptic neuron.

Micturation is what we commonally call urination. There are various stretch activated receptors within the bladder and in the adjoining sphincter that participate in the reflex. The bladder has to disallow backflow and coordinate the contraction of the bladder with the relaxation of the terminal sphincter. This is done through both voluntary control of the musculature as well via sympathetic and parasympathetic reflexes.
When beta receptors are stimulated, it decreases the heart rate to treat for low blood pressure.
Mechanoreceptors
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 Adaptation, which is an adjustment made by the sensory receptors upon continuous stimulation.
Nociceptors are stimulated by tissue damage and are also called pain receptorsSourceIntroduction to the Human Bodyby Gerard Tortora and Bryan Derrickson
There are many sense organs in the body like touch receptors, pressure receptors, heart receptors, taste receptors, sound receptors, etc. All these receptors when stimulated result in changes in tone or isometric contraction of skeletal muscles around them or in the entire body.Sensation:Sensation is the observation of change in tone of skeletal muscles induced by a single sense organ.Thus, heat, sound, etc are sensations.Feeling:Feeling is the observation of changes in tone of skeletal muscles induced by many sense organs or continuous changes in a single sense organ.Thus, coffee induces a feeling and so does a song.
