What is a Tessier cleft?

Tessier facial clefts are a series of severe facial clefts that involve more than just the lip and the upper jaw (as in a cleft lip and/or cleft palate). A Tessier cleft involves the mouth, cheeks, eyes, ears, and forehead and may continue on into the hairline.

What is the Prolabium?

[ prō-lā′bē-əm ] n. The exposed part of the lip, especially the small elevation at the termination of the philtrum.

Is cleft lip congenital?

A cleft palate or cleft lip (or both) is a birth condition in which parts of the mouth do not join up during early fetal development. The cause is unknown, although genetic factors sometimes play a role. Cleft conditions vary in severity and extent. A cleft lip or palate can be repaired through surgery.

Where is cleft located?

The natal cleft is the deep groove which runs between the two buttocks from just below the sacrum to the perineum. Depending on how developed a person’s gluteal muscles are, the depth of this crease varies. In those that are especially deep and hairy, the natal cleft can be the site of a very nasty condition.

What is Dentary bone?

Definition of dentary : either of a pair of membrane bones of the lower jaw of most vertebrates, in lower forms being restricted to the distal area but in recent higher mammals forming the body of the mandible.

What is Intermaxillary suture?

Why is my uvula split in two?

Both a cleft palate and a bifid uvula may be hereditary. They can also be the result of genetic conditions or caused by environmental factors. Smoking, certain medications, and diabetes can increase the risk of delivering a baby with a cleft palate.

What are the parts of the eyeball?

The front section of the eye’s interior where aqueous humor flows in and out, providing nourishment to the eye. Aqueous humor. The clear watery fluid in the front of the eyeball. Blood vessels. Tubes (arteries and veins) that carry blood to and from the eye.

Which part of the eye produces aqueous humor?

The part of the eye that produces aqueous humor. Cornea. The clear, dome-shaped surface that covers the front of the eye. Iris. The colored part of the eye. The iris is partly responsible for regulating the amount of light permitted to enter the eye.

What is the fluid in the anterior chamber of the eye?

Behind the cornea is a fluid-filled space called the anterior chamber. The fluid is called aqueous humor. The eye is always producing aqueous humor. To maintain a constant eye pressure, aqueous humor also drains from the eye in an area called the drainage angle.

What is behind the pupil of the eye?

Behind the anterior chamber is the eye’s iris (the colored part of the eye) and the dark hole in the middle called the pupil. Muscles in the iris dilate (widen) or constrict (narrow) the pupil to control the amount of light reaching the back of the eye. Directly behind the pupil sits the lens.
