TWO
Skin can detect temperature changes, allowing us to feel hot or cold sensations. It also detects physical stimuli such as pressure, touch, and pain.
The stimuli for touch are mechanical pressure, temperature, and vibration on the skin's surface. Specialized receptors in the skin, such as Meissner's corpuscles, Pacinian corpuscles, and Merkel cells, detect these stimuli and send signals to the brain through the nervous system, enabling us to perceive touch sensations.
The main source of energy for skin sensation is the activation of sensory nerve fibers in the skin that respond to various stimuli such as touch, temperature, and pain. These nerve fibers transmit signals to the brain, which processes the information and creates the sensation of touch or other skin-related stimuli.
Hot stimuli are detected by heat-sensitive receptors called thermoreceptors, while cold stimuli are detected by cold-sensitive receptors in the skin known as cold thermoreceptors. These receptors are specialized nerve endings that are able to detect changes in temperature and transmit this information to the brain to generate the sensation of heat or cold.
Stimuli in sense organs are external signals that trigger a response in the sensory receptors, such as light for the eyes, sound waves for the ears, chemicals for taste and smell receptors, pressure for touch receptors, and temperature for thermoreceptors. These stimuli are converted into electrical signals that are then transmitted to the brain for interpretation.
The organ receives stimuli from the skin and mucous membranes.

In order for the body to respond to external stimuli, it must first receive the stimuli through the sensory organs. These organs, such as the eyes, ears, skin, nose, and tongue, detect various forms of stimuli, including light, sound, touch, taste, and smell. The sensory information is then transmitted to the brain for processing, allowing the body to react appropriately.

The epidermis.
Three examples of stimuli that skin can respond to are temperature changes (hot or cold), touch or pressure, and exposure to chemicals or irritants.
excitability
The olfactory nerves receive stimuli related to smell, specifically detecting different odors and scents in the environment. These stimuli are converted into nerve impulses that travel to the brain, allowing us to perceive and identify various smells.
