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.

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.
Stimulation of beta receptors leads to increased heart rate, relaxation of bronchial smooth muscle, and release of glucose from the liver. This can result in increased blood flow to muscles, improved airway function, and a boost in energy levels to support physical activity.
Mechanoreceptors are stimulated by changes in pressure or movements of body fluidsSourceIntroduction to the Human Bodyby Gerard Tortora and Bryan Derrickson
Semicircular canals, filled with fluid, are involved in dynamic equilibrium. The tubes are oriented in three planes: horizontal, frontal, and sagittal. They respond to changes in the position of the head.
Thermoreceptors
Mechanoreceptors
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.
Sensory impulses at receptors are typically stimulated by specific environmental stimuli such as light, sound, touch, temperature, or chemicals. These stimuli activate specialized receptors on sensory neurons, which then generate neural signals that are transmitted to the brain for further processing and interpretation.

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.

Yes, that's correct. Sour taste receptors on the taste buds are stimulated by the presence of hydrogen ions in acidic food substances. When these ions bind to specific receptors on taste cells, they generate a signal that is sent to the brain, which we perceive as sour taste.
