How Do You Spell DUCTUS LACRIMALIS?

1. The ductus lacrimalis, also known as the lacrimal duct or tear duct, refers to a small tube-like structure in the human body that helps drain tears from the eyes. It is a crucial part of the lacrimal system, which is responsible for producing, distributing, and draining tears to keep the eyes lubricated and clean.

   The ductus lacrimalis begins at the inner corner of the eye, where it connects to the lacrimal sac. From there, it extends downward, passing through a bony channel called the nasolacrimal duct, which connects the eye to the nasal cavity. This canal allows tears to flow from the lacrimal sac to the nasal cavity, ultimately joining the rest of the respiratory system.

   The primary function of the ductus lacrimalis is to drain accumulated tears away from the eyes. When tears are produced by the lacrimal gland, they are spread across the surface of the eye by blinking. Excess tears and fluids then enter the lacrimal puncta, two small openings located in the inner corners of the upper and lower eyelids. From there, they empty into the lacrimal sac, which leads to the ductus lacrimalis. The ductus lacrimalis then collects these tears and transports them into the nasal cavity, allowing for their eventual removal from the body.

   In summary, the ductus lacrimalis is an essential channel within the lacrimal system, playing a crucial role in draining tears and maintaining the health and lubrication of the eyes.

2. Lacrymal duct, a curved canal beginning at the punctum lacrimale in the margin of each eyelid near the medial commissure and running transversely inward to empty with its fellow into the lacrymal sac.
