1204 Nose Anatomy Study Resources

Olfactory BulbA neural structure of the forebrain involved in the sense of smell; receives neural input about odours detected by cells in the nasal cavity.
Olfactory Receptor CellsNeurons located in the olfactory epithelium that contain receptors for odorant molecules; they send signals to the brain when these molecules are detected.
Olfactory CiliaHair-like extensions on the olfactory receptor cells that increase the surface area for detecting odorant molecules.
Olfactory EpitheliumA specialized epithelial tissue inside the nasal cavity responsible for detecting odors.
AxonsLong, slender projections of neurons that conduct electrical impulses away from the neuron's cell body to the olfactory bulb.
GlomeruliStructures within the olfactory bulb where synapses form between the axons of the olfactory receptor neurons and the dendrites of other neurons.
Basal CellsStem cells in the olfactory epithelium that can differentiate into new olfactory receptor neurons.
Nasal BoneThe bones that form the bridge of the nose.
Upper Lateral CartilageCartilage that helps to shape the mid-section of the nose.
Lower Lateral CartilageAlso known as alar cartilage, these cartilages shape the nostrils and contribute to the form of the nasal tip.
Septal CartilageCartilage forming the septum, which divides the nasal cavity into two chambers.
ColumellaThe tissue that links the nasal tip to the nasal base, influencing the nasal tip's angle and support.
Middle CrusThe part of the lower lateral cartilage that contributes to the shape of the nasal tip.
Lateral CrusThe part of the lower lateral cartilage that contributes to the structure and shape of the nostril walls.
Nasal SeptumThe bone and cartilage wall that separates the nasal cavity into two separate chambers.
Minor Alar CartilagesSmaller cartilages that provide additional structure and contour to the nose.
Sphenoid SinusAn air-filled space within the sphenoid bone, part of the paranasal sinus system.
Frontal SinusOne of the four pairs of paranasal sinuses, located in the frontal bone, just above the eyes.
Maxillary SinusA pair of sinuses located in the maxillary bones, the largest of the sinuses.
Ethmoidal Air CellsNumerous small air cells within the ethmoid bone that form part of the paranasal sinus system.
Cribriform PlateA sieve-like structure at the base of the skull that allows the passage of the olfactory nerves from the nasal cavity to the olfactory bulb.
RadixThe root or beginning of the nose where it meets the forehead.
PinionThe outermost part of the nasal bones where they join with the cartilage. (Note: Pinion is not a standard anatomical term and may vary in use.)
Sesamoid CartilagesAdditional small cartilages found near the nasal tip, often manipulated in nasal surgery.
Fibro-Areolar TissueConnective tissue layer that covers the cartilages and muscles of the nose, allowing for the flexibility of the nasal tip.
Anterior Nasal SpineA bony projection of the maxilla at the base of the nose that provides attachment for the columella.
Turbinates/ConchaeLong, narrow shelves of bone that protrude into the nasal cavity; they increase the surface area of the nasal passages, aiding in warming and humidifying inhaled air.
