What type of stimulus detected by touch receptor?
The criteria used to classify sensory receptors depends on the type of nerve signals associated with the sensory receptors. Olfactory receptors read chemical signals and associate them with a corresponding smell, tastebuds read chemical signals and associate them with a corresponding taste ect..
How do olfactory receptor cells work to make smell possible?
The olfactory bulb is actually a tiny lobe of the brain. There are many thousands of different cell types in the olfactory bulb, each with receptors for different chemicals. When these receptors bind to their matching chemical in the air they become excited and trigger a nearby olfactory nerve cell. Details of what happens after this have yet to be worked out, but basically the firing of these nerve cells is analyzed by nerve circuits in the rest of the olfactory bulb then transferred to the brain, where we call it "smell".
What are know as the 'chemical senses'?
Chemical senses are senses that require chemicals to stimulate them. Taste and smell are both chemical senses. All other senses are considered mechanical or electrical.
Tastes are distinguished by?
chemical receptors
When the level of increases in the blood chemical receptors will the medulla oblongata?
when the level of oxygen increases in the blood , chemical receptors will inhibit the medulla oblongata
What is the relationship between olfactory and gustatory receptors?
Gustatory receptors are part of the sense of taste. They are in your mouth. Olfactory receptors are part of the sense of smell. They are in your nose.
What is the sensory organ for smell?
"olfactory" They are chemical receptors, in your nasal sinuses.
What are two classifications of sensory receptors?
There are many different sensory receptors, but olfactory receptors in the nose, and cones and rods in the eyes are two specific types of sensory receptors. Olfactory detects the chemical presence and your brain identifies it as a smell. The rods and cones of the eye process light and color to form images that your brain processes as vision.

What is the nerve for smell?
The olfactory nerves are cranial nerves( arise from the brain ). olfactory nerve is the first nerve among the all cranial nerves. olfactory nerves passes sense of smell through nerve impulses( chemical=neurotransmitters, and electrical signals ).

What in the human brain do addictive substances like nicotine react with'?
Chemical Receptors
Both olfactory receptors and taste buds are?
Both are chemical sensory receptors. They function by determining their corresponding sensation and conveying it to afferent neurons to the brain.
Can your sense of smell alter your sense of taste?
Much of what most people consider "taste" actually is smell. Most fruit really tastes pretty similar... if you plug up your nose so you can't smell it, the difference between two fruits of similar acidity and sweetness is mainly in the texture. So, in that sense, yes. There is no direct causal relationship on a physical level because taste and smell are mediated by different types of receptors detecting different types of chemical compounds. Smell is carried from olfactory receptors in the nose to the brain via the Olfactory Nerve (cranial nerve I). Taste is carried from gustatory receptors on the tongue to the brain via the Facial Nerve and the Glossopharyngeal Nerve (cranial nerves VII and IX). However, these signals are integrated extensively in the cerebrum and many connections are made. Therefore, it is plausible that the mere smell of a certain type of food can elicit the memory of the taste of that particular food.
