- An orbital blowout fracture is a fracture or break in the small bones that make up your eye. The orbit, or eye socket, is the cavity of the skull that holds the eye. An orbital blowout can occur when an object strikes the orbit with blunt force. This injury is commonly the result of a fist, baseball or tennis ball that strikes the eye. The bony orbit's job is to protect the eyeball.

- The nasal cavity (or nasal fossa) is a large air filled space above and behind the nose in the middle of the face. Each cavity is the continuation of one of the two nostrils.ilia and mucus along the inside wall of the nasal cavity traps and removes dust and pathogens from the air as it flows through the nasal cavity. The cilia move the mucus down the nasal cavity to the pharynx, where it can be swallowed.

Orbit (anatomy) This article is about the orbit, the anatomical space that contains the eye. For other uses of orbit or orbita see Orbit (disambiguation) and Orbita (disambiguation) . In anatomy, the orbit is the cavity or socket of the skull in which the eye and its appendages are situated.Orbit can refer to the bony socket, or it can also be used to imply the contents. In the adult human, the volume of the orbit is 30 mL, of which the eye occupies 6.5 mL.he orbits are conical or four-sided pyramidal cavities, which open into the midline of the face and point back into the head. Each consists of a base, an apex and four walls. There are two important foramina, or windows, two important fissures, or grooves, and one canal surrounding the globe in the orbit.

Orbital Cellulitis â Useful Information Orbital cellulitis is an infection that affects the tissues that surround the eye which also include the eyebrow, cheek and eyelids. If not diagnosed and treated promptly, orbital cellulitis is serious enough to cause blindness and other complications such as hearing loss, meningitis and blood infections.

The Human Eye Anterior Chamber. The cavity in the front part of the eye between the lens and cornea is called the Anterior Chamber. It is filled with Aqueous, a water-like fluid. This fluid is produced by the ciliary body and drains back into the blood circulation through channels in the chamber angle.

- The nasal cavity is part of the human respiratory system. Also known as the nasal fossa, it is a small air-filled chamber behind the nose, connected via the pharynx to the l … arynx (voicebox) and the trachea. Above and in front of the nasal cavity are the sinuses (paranasal cavities), located inside the facial bones.

Eye Anatomy: How Do Our Eyes Work? It is a gel-like substance in the back part of the eye that provides the shape of the eyeball. The vitreous humor is located between the lens and the retina, in an area called the vitreous cavity.Besides helping to maintain the shape of the eyeball, the vitreous cavity also provides a clear pathway for light going through the eye to the retina. The Aqueous Humor is the watery region in the front of the eyeball.he Lens. The lens is a clear structure behind the pupil that does just what a regular lens does. The main purpose of the lens is to focus light by changing shape. The ciliary body is a muscle group attached to the lens that help the lens change its shape to better focus light on the retina.

Chapter 45: The orbit The orbits (figs. 45-1 and 45-2) are two bony cavities occupied by the eyes and associated muscles, nerves, blood vessels, fat, and much of the lacrimal apparatus. Each orbit is shaped like a pear or a four-sided pyramid, with its apex situated posteriorly and its base anteriorly.

The Nasal Cavity The nose is an olfactory and respiratory organ. It consists of nasal skeleton, which houses the nasal cavity. In this article, we shall look at the applied anatomy of the nasal cavity, and some of the relevant clinical syndromes.his is carried out by the olfactory nerves. The olfactory bulb, part of the brain, lies on the superior surface of the cribriform plate, above the nasal cavity. Branches of the olfactory nerve run through the cribriform plate to provide special sensory innervation to the nose.

- 1 Frontal sinuses: The right and left frontal sinuses are located in the center of the forehead (frontal bone) just above each eye. 2  Maxillary sinuses: These are the largest of the sinuses and are located behind the cheekbones near the maxillae, or upper jaws.inus Cavities. Sinuses are air-filled sacs on either side of the nasal cavity that clean the air breathed through the nose and lighten the bones of the skull, providing shape to the face.

Ocular injuries Ocular injuries The bony orbit provides excellent protection for the eye, especially from blunt injuries. A blow to the front of the orbit with a rounded instrument such as a fist or a tennis ball, however, can cause a shock wave to travel through the eye, damaging many structures along the way, including the retina.

- Frontal sinus. The frontal sinuses are pockets of space located above the orbit of each eye in the frontal bone. They are lined with mucus membrane, which secretes fluid that moistens and protects the areas it covers. The size and shape of the frontal sinus can vary from person to person. These spaces fill up with mucus, which then drain into the nose.

- Post 1. I did not know that the supraorbital ridge was the ridge above the eye. It makes sense though since orbital has to do with the eye, I think. I also did not know that the supraorbital bone structure of the skull has changed so much over time and species, and even race!
