Nose
Nose

A specialized structure that serves as an organ of the sense of smell as well as part of the respiratory system; the term includes both the external nose and the nasal cavity.

Nasal Septum
Nasal Septum

The partition separating the two nasal cavities in the midplane, composed of cartilaginous, membranous and bony parts.

Turbinates
Turbinates

The scroll-like bony plates with curved margins on the lateral wall of the nasal cavity.

Nasal Bone
Nasal Bone

Either of two small elongated rectangular bones that together form the bridge of the nose.

Goblet Cells
Goblet Cells

A glandular epithelial cell or a unicellular gland. Goblet cells secrete MUCUS. They are scattered in the epithelial linings of many organs, especially the SMALL INTESTINE and the RESPIRATORY TRACT.

Nasal Cavity
Nasal Cavity

The proximal portion of the respiratory passages on either side of the nasal septum, lined with ciliated mucosa, extending from the nares to the pharynx.

Olfactory Mucosa
Olfactory Mucosa

That portion of the nasal mucosa containing the sensory nerve endings for SMELL, located at the dome of each NASAL CAVITY. The yellow-brownish olfactory epithelium consists of OLFACTORY RECEPTOR NEURONS; brush cells; STEM CELLS; and the associated olfactory glands. Vomeronasal Organ;

Olfactory Receptor Neurons
Olfactory Receptor Neurons

Neurons in the OLFACTORY EPITHELIUM with proteins (RECEPTORS, ODORANT) that bind, and thus detect, odorants. These neurons send their DENDRITES to the surface of the epithelium with the odorant receptors residing in the apical non-motile cilia. Their unmyelinated AXONS synapse in the OLFACTORY BULB of the BRAIN.

Vomeronasal Organ
Vomeronasal Organ

A specialized part of the olfactory system located anteriorly in the nasal cavity within the nasal septum. Chemosensitive cells of the vomeronasal organ project via the vomeronasal nerve to the accessory olfactory bulb. The primary function of this organ appears to be in sensing pheromones which regulate reproductive and other social behaviors. While the structure has been thought absent in higher primate adults, data now suggests it may be present in adult humans.

Paranasal Sinuses
Paranasal Sinuses

Air-filled extensions of the respiratory part of the nasal cavity into the frontal, ethmoid, sphenoid, and maxillary cranial bones. They vary in size and form in different individuals and are lined by the ciliated mucous membranes of the nasal cavity.

Maxillary Sinus
Maxillary Sinus

One of the paired paranasal sinuses, located in the body of the maxilla, communicating with the middle meatus of the nasal cavity.

Sphenoid Sinus
Sphenoid Sinus

One of the paired paranasal sinuses, located in the body of the sphenoid bone and communicating with the highest meatus of the nasal cavity on the same side.

Ethmoid Sinus
Ethmoid Sinus

Numerous small thin-walled spaces or air cells in the ethmoid bone, where they form an ethmoidal labyrinth.

Frontal Sinus
Frontal Sinus

One of the paired, but seldom symmetrical, air spaces located between the inner and outer compact layers of the frontal bone.
