What type of receptors responds to changes in the concentrations?
Chemical stimuli can be detected by a chemoreceptors that detect chemical stimuli, such as a chemicals that lead to the sense of smell. Osmoreceptors respond to solute concentrations of body fluids.
Which receptor is stimulated by changes in the concentration of a certain chemical in the body?
A chemoreceptor, also known as chemosensor, is a specialized sensory receptor cell which transduces a chemical substance (endogenous or induced) to generate a biological signal.

What is the correct sequence of olfactory information?
The correct sequence of olfactory information is: chemoreceptors → olfactory nerves → olfactory bulb → olfactory tract → cerebrum.
What are the five major types of sensory receptors?
Key Takeaways
- Chemoreceptors detect the presence of chemicals.
- Thermoreceptors detect changes in temperature.
- Mechanoreceptors detect mechanical forces.
- Photoreceptors detect light during vision.
- More specific examples of sensory receptors are baroreceptors, propioceptors, hygroreceptors, and osmoreceptors.

What type of stimulus is detected by the sensory receptors of the skin?
Glabrous skin and hairy skin contain a wide variety of sensory receptors for detecting mechanical, thermal, or nociceptive (consciously perceived as painful) stimuli applied on the body surface. These receptors include bare nerve endings (nociception, thermal sensation) and encapsulated endings.
Why is scent so powerful?
Scent is more powerful than you think… The sense of smell (or olfaction) is our most primitive sense and yet is one of the most powerful senses that cannot be turned off. One reason is that olfactory system is located in the same part of our brain that effects emotions, memory, and creativity.
What is smelling trigger memories called?
Decades later, researchers hypothesized that the exceptional ability that smells have to trigger memories — known as “the Proust effect” — is due to how close the olfactory processing system is to the memory hub in the brain.
In what sequence is olfactory information sent to the brain?
The olfactory epithelium, found within the nasal cavity, contains olfactory receptor cells, which have specialized cilia extensions. The cilia trap odour molecules as they pass across the epithelial surface. Information about the molecules is then transmitted from the receptors to the olfactory bulb in the brain.
Where is the primary olfactory cortex located?
temporal lobe
The Chemical Senses Mitral cells and tufted cells send their process to the primary olfactory cortex, which is located on the inferior surface of the temporal lobe.
