The usual example is when you smell good food, your mouth starts watering.
The human body has five sense organs: sight, hearing, touch, taste and smell. The largest sense organ is touch, which involves the skin.

An example could be hearing your phone ring (stimulus) and then picking it up to answer the call (response).
sense organ
A Receptor is referring to a sense organ, like a nerve ending. An Effector is referring to a muscle capable of reflecting to a stimulus. By definition, receptor and effector are antonyms.

Without the sense organs animals wont be able to sense their enemies. It is believed that today Man is a great threat to the animal kingdom. It is therefore necessary for animals to have sense organs.
There are five main senses that people experience: sight, smell, taste, touch, and hearing. Each sense is associated with different physical stimuli. For example, the sense of sight is associated with light waves, the sense of smell is associated with volatile molecules, the sense of taste is associated with dissolved molecules, the sense of touch is associated with pressure or temperature changes, and the sense of hearing is associated with sound waves. The relationship between a physical stimulus and the resulting sensory response is that the physical stimulus is converted into a neural signal by the sense organ, and then this neural signal is interpreted by the brain to produce the sensory response. The specific response depends on which sense is involved and what the physical stimulus is.
The brain is a organ. The brain is the organ that receives messages from the six senses; the touch sense, the seeing sense, the hearing sense, the smelling sense and the tasting senses. If you are asking 'Is the brain the largest organ?' Well, no. The largest organ is not the brain, or the chest, or the stomach. It is the skin.

The skin is both a sense and excretory organ.
Stimulus are patterns of energy that activate sense organs. Sense organs are the eyes, nose, tongue, ears, and skin of people.
-- The organ of the sense of sight is the eye, including the optic nerve. -- The organ of the sense of hearing is the ear, including the middle and inner ones. -- The organ of the sense of smell is the nose and the olfactory nerves. -- The organ of the sense of taste is the tongue and its taste buds. -- The organ of the sense of touch is the skin and its nerve endings.
In science, the word stimulus is used to describe something that evokes a response or reaction from a living subject, whether it be a touch, a sound, etc. A few examples of stimulus: - bright light (affects sense organs and receptors) - physically touching the subject (external stimulus) - loud noise (affects sense organs and receptors)
A sense organ is an organ of the 6 senses. The sense organs and senses are: the eyes--sight the nose--smell the tongue--taste the ears--hearing and balance the skin--touch
