The nasal cavity contains turbinate bones that protect the mucous membrane that lines the cavity from warm inspired air. The skull consists of fourteen major bones Incisive bone (premaxillary): part of the upper jaw; where the incisors attach; Nasal bones: cover the nasal cavity; Maxillary bones: large bones that contain the roots of the molars
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 ...
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]
The canal containing the duct is called the nasolacrimal canal.It is formed by indentations in the inferior nasal conchae, maxilla and lacrimal bone.The canal drains into the nasal cavity through the anterior portion of the inferior meatus, which is between the inferior concha and the floor of the nasal cavity.
The lower leg bones of a horse correspond to the bones of the human hand or foot, and the fetlock (incorrectly called the "ankle") is actually the proximal sesamoid bones between the cannon bones (a single equivalent to the human metacarpal or metatarsal bones) and the proximal phalanges, located where one finds the "knuckles" of a human.
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 ...
The lateral nasal cartilage and major alar cartilage curl up upon interaction with one another, forming a tight connection through fibrous tissues. Like the septal nasal cartilage, the lateral nasal cartilage is composed of hyaline cartilage. Hyaline cartilage provides form and flexibility within a specific structure.
