Lacrimal bones: contains the nasolacrimal duct, which carries fluid from the surface of the eye, to the nose; Ethmoid bone: complex bone separating the nasal passages from the cranial vault; Frontal bone: creates the forehead of the horse; Parietal bones: extend from the forehead to the back of the skull
Due to the length of the nasal cavity, there is a large area of these receptors, and the horse has a better ability to smell than a human. Additionally, the horse also has a vomeronasal organ, or Jacobson's Organ, which is in the hard palate, and is able to pick up pheromones and other scents when a horse exhibits the flehmen response. The ...
Points of a horse. Equine anatomy encompasses the gross and microscopic anatomy of horses, ponies and other equids, including donkeys, mules and zebras.While all anatomical features of equids are described in the same terms as for other animals by the International Committee on Veterinary Gross Anatomical Nomenclature in the book Nomina Anatomica Veterinaria, there are many horse-specific ...
A thin duct, which opens onto the floor of the nasal cavity inside the nostril, is the only way of access for stimulus chemicals. During embryological development, the vomeronasal sensory neurons form from the nasal (olfactory) placode, at the anterior edge of the neural plate (cranial nerve zero).
The topmost bony part of the nose is formed by the nasal part of the frontal bone, which lies between the brow ridges, [3] and ends in a serrated nasal notch. [4] A left and a right nasal bone join with the nasal part of the frontal bone at either side; and these at the side with the small lacrimal bones and the frontal process of each maxilla. [3]
Broadly, most nasal bones can be categorized as "V-shaped" or "S-shaped" but these are not scientific or medical categorizations. When viewing anatomical drawings of these bones, consider that they are unlikely to be accurate for a majority of people. [1] The two nasal bones are joined at the midline internasal suture and make up the bridge of ...

Illustration of upper respiratory system. In anatomy, a nasal concha (/ ˈ k ɒ n k ə /; pl.: conchae; / ˈ k ɒ n k iː /; Latin for 'shell'), also called a nasal turbinate or turbinal, [1] [2] is a long, narrow, curled shelf of bone that protrudes into the breathing passage of the nose in humans and various other animals.
