Any of the olfactory glands, or branched tubular alveolar glands located in the olfactory lamina of the olfactory membrane. Mucus from these glands keeps the olfactory surface moist.
What do Bowman's glands secrete?
Bowman's glands can secrete proteins such as lysozyme, amylase and IgA similar to serous glands. The exact composition of Bowman's gland secretions is unclear, but there is evidence that Bowman's glands do not produce odorant-binding protein [WP].
What are scent glands?
n. Any of the branched tubuloalveolar glands located in the mucosa of the olfactory region of the nasal cavity that produce mucus to moisten the olfactory epithelium and dissolve odorous gases. Bowman's gland.
Which gland is responsible for smell?
The olfactory system, or sense of smell, is the sensory system used to smell (smell). Smell is one of the special senses which have directly connected specific organs. Most mammals and reptiles have a primary olfactory system and an accessory olfactory system. …

What do olfactory cells do?
stimulate these sensory cells. … When the cells detect the molecules, they send messages to our brain where we recognize the smell. Olfactory or olfactory nerve cells are stimulated by the smells around us – the smell of a gardenia or the smell of bread.
What do you call the sense of smell?
The molecules that activate the sense of smell (the technical name is odors) are airborne. They enter the body through the nose and mouth and bind to receptor cells that line the mucous membranes far back in the nose. … The axons join the olfactory nerve and go directly to the brain.
What are Olfactory Nerves?
The olfactory nerve is the first cranial nerve (CN I). It is a sensory nerve that functions for the sense of smell. … It is carried out through a special visceral afferent nerve. It is a cranial nerve with some unique properties, such as the lack of a precortical connection with the thalamus.
What is the olfactory epithelium?
The olfactory epithelium located in the nasal cavity contains olfactory receptor cells that have specialized cilia extensions. Cilia capture odor molecules as they pass over the epithelial surface. Information about the molecules is then transferred from receptors in the olfactory bulb to the brain.
How is mucus produced by the olfactory glands?
Olfactory receptor cells have long cilia that protrude into a layer of mucus secreted by Bowman's glands in the olfactory epithelium.
How do birds smell?
While most birds seem to lack much of a sense of smell, there are some groups of birds that can smell. They find food using their olfactory glands. Extensive research into avian senses has shown that vultures, seabirds, kiwis and parrots have well-developed olfactory glands, giving them some sense of smell and taste.
What is the process of smelling?
In humans, the olfactory process begins when volatile molecules enter the nasal cavity and activate receptors in the olfactory epithelium (OE). … Signals from OR cells responding to odorants and their metabolites are received by the olfactory bulb (OB).
What is a mitral cell?
a cell in the olfactory bulb that carries olfactory information from the olfactory bulb to the rest of the brain (eg, the olfactory cortex) for processing.
Where is Bowman's gland located?
olfactory mucosa Olfactory glands, also known as Bowman's glands, are a type of nasal glands located in the olfactory mucosa, below the olfactory epithelium, in the lamina propria, a connective tissue that also contains fibroblasts, blood vessels and bundles of fine axonal fiber neurons.
What part of your nose smells?
The nose smells from the olfactory cleft, which is taken from the nasal cavity. It is located right next to the "olfactory" part of the brain, which consists of the olfactory bulb and the fovea.
What is armpit odor?
Apocrine glands work mainly under pressure and secrete an odorless fluid. This liquid begins to develop an odor when it comes into contact with bacteria on your skin. These glands don't start working until puberty, so it's normal when we start to notice body odor.
Why do smells evoke memories?
Odors bypass the thalamus and go directly to the olfactory center of the brain, known as the olfactory bulb. The olfactory bulb is directly connected to the amygdala and hippocampus, which may explain why smelling something can so instantly trigger a detailed memory or even a strong emotion.
What is the nasal epithelium?
The olfactory epithelium is a thin, cellular tissue that extends along the roof of the nasal cavity. In adults, it is about 7 centimeters (cm) behind the nostrils. It is part of the nasal septum and superior turbinal bones. Olfactory receptor cells have hair-like extensions called cilia. …
What is the olfactory receptor?
The brain's olfactory bulb processes information from the olfactory receptors that line the nose. Olfactory receptor, also called olfactory receptor, protein capable of binding odor molecules that play a central role in the sense of smell (sense of smell).
What is Amosia?
Anosmia, also known as smell blindness, is the loss of the ability to detect one or more smells. Anosmia can be temporary or permanent. It differs from hyposmia, which is reduced sensitivity to some or all smells.
What is the scientific name of the taste?
The gustatory system or sense of taste is the sensory system partially responsible for the perception of taste (taste). … Humans have taste receptors in their taste buds and in other areas, including the upper surface of the tongue and the epiglottis. The gustatory cortex is responsible for the perception of taste.
What is it called when you can't taste?
Some people cannot detect taste, which is called tastelessness [ah-GYOO-zee-a]. However, true loss of taste is rare. Most of the time, people experience a loss of smell rather than a loss of taste. In other disorders of the chemical senses, a smell, taste or taste may be distorted.
Which nerve helps you swallow?
glossopharyngeal nerve The glossopharyngeal nerve activates the muscles involved in swallowing and tasting.
Which nerve controls taste?
The facial nerve (CN VII) innervates the anterior two-thirds of the tongue, the glossopharyngeal nerve (CN IX) innervates the posterior third of the tongue, and the vagus nerve (CN X) carries taste information from the back of the mouth, including the upper third of the esophagus.
Which nerve is taste?
The three nerves associated with taste are the facial nerve (cranial nerve VII), which supplies fibers to the anterior two-thirds of the tongue. the glossopharyngeal nerve (cranial nerve IX), which supplies fibers to the posterior third of the tongue. and the vagus nerve (cranial nerve X), which supplies fibers to...
What is the nasal cavity?
(NAY-zul KA-vuh-tee) The space inside the nose. The nasal cavity lies above the bone that forms the roof of the mouth and curves down at the back to join the throat. It is divided into two sections called the nasal passages. Air moves through these passages during breathing.
What is between the lens and the retina?
crystals. This is between the lens and the retina. This outer layer of dense connective tissue serves to protect the inner parts of the eyeball.
What is the Cribriform plate?
The rigid plate is a transverse plate, pierced by several small holes, forming the anteroventral wall of the cranial cavity. From: The Dissection of Vertebrates (Second Edition), 2011.
What are odors and smells?
Detecting a taste (taste) is quite similar to detecting a smell, in that both taste and smell are based on chemical receptors that are stimulated by certain molecules. The most important taste organ is the taste bud.
Where is the respiratory lining located?
The mucous membrane that lines the respiratory tract, including the nasal cavity. LARYNX; TRACHEA; and the LOOP tree.
Where do the olfactory nerves pass through?
ethmoid bone The olfactory nerves (I) are special sensory nerves for the sense of smell. They originate from the receptors in the olfactory epithelium and pass through the olfactory foramina in the rough plate of the ethmoid bone, ending in the olfactory bulbs.

I graduated from ENSAT (national agricultural school of Toulouse) in plant science in 2018, followed a CIFRE PhD under contract with Sun'Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrovoltaic systems, in my case in wood use. I enjoy writing and sharing science related stuff here on my site. I am currently continuing at Sun'Agri as an R&D engineer.
