Where is the olfaction?
olfactory system, the bodily structures that serve the sense of smell. The system consists of the nose and the nasal cavities, which in their upper parts support the olfactory mucous membrane for the perception of smell and in their lower parts act as respiratory passages.
How many glomeruli are in the nose?
2000 glomeruli
There are tens of millions of olfactory receptor cells, but only about 2000 glomeruli. Glomeruli receive input from between 5000 and 10,000 olfactory receptor cells but output onto only 10 to 25 mitral cells.
What’s the meaning of olfaction?
the sense of smell
Definition of olfaction 1 : the sense of smell. 2 : the act or process of smelling.
Is olfaction a chemical sense?
Olfaction is a chemical sense, not a spectral sense. Whether in humans or flies, odorants bind and activate receptors through a combination of chemical features no different from other types of receptor-based molecular signaling in biology (5).
Where are the glomeruli located?
the kidney
The glomerulus is a network of capillaries known as a tuft located at the beginning of nephrons in the kidney. Intraglomerular mesangial cells support the structure of the tuft. The blood in the tuft is filter’s capsule. Then the filtrate of water and soluble substances enters the renal tubules of the nephron.
What do glomeruli do?
Glomeruli work like strainers used in cooking. While blood moves through them, they let waste and extra water pass into the nephrons to make urine. At the same time, they hold back the protein and blood that your body needs. Many diseases affect kidney function by attacking the glomeruli.
What is an example of olfaction?
Olfaction is a major sense in animals. For example, humans detect odors through the olfactory epithelium of the nose, whereas most insects detect odors through their antennae.
