How Do You Spell CILIARY CANAL?

1. Ciliary canal refers to a narrow passage or channel found in the eye, specifically within the ciliary body. The ciliary body is a ring-shaped structure located between the iris and the choroid, and it plays a crucial role in the production and regulation of the aqueous humor, a clear fluid that fills the front part of the eye.

   The ciliary canal, also known as the canal of Petit, is a tiny channel that runs within the ciliary body. It is lined with ciliary epithelium, a specialized layer of cells that produce aqueous humor. The canal connects the posterior chamber of the eye, which is located behind the iris, with the anterior chamber, located in front of the iris. This connection allows for the proper flow and drainage of the aqueous humor within the eye.

   The ciliary canal is responsible for maintaining the necessary intraocular pressure, which is essential for supporting the shape of the eye and providing nutrients to the cornea and lens. It acts as a conduit, allowing the aqueous humor to flow smoothly from the posterior chamber to the anterior chamber, where it nourishes the lens and cornea before being drained through the trabecular meshwork and Schlemm's canal.

   Understanding the structure and function of the ciliary canal is crucial in the study and treatment of various eye conditions, including glaucoma, which can result from an imbalance of aqueous humor production and outflow.
