Rivus lacrimalis is a Latin term that refers to the tear ducts of the eye. The pronunciation of this phrase is "ˈriːwʊs lækrɪˈmeɪlɪs" in IPA phonetic transcription. The spelling of this term is relatively straightforward as it follows the standard Latin spelling conventions. The pronunciation features a long "i" sound in "rivus" and a long "a" sound in "lacrima". The emphasis in the first word falls on the initial syllable, while the emphasis in the second word falls on the second syllable.
Rivus lacrimalis is a Latin term that translates to "tear duct" in English. It refers to a small tubular passage within the human body that is responsible for carrying tears from the lacrimal gland to the surface of the eye.
Tears play a crucial role in maintaining the health and lubrication of the eyes. The lacrimal gland, located in the upper outer corner of each eye socket, is responsible for producing tears. These tears contain a mixture of substances, including water, mucus, oils, antibodies, and enzymes.
The rivus lacrimalis, or tear duct, starts at the lacrimal punctum, a tiny opening near the inner corner of the eyelid. From there, it traverses through a canal called the lacrimal canaliculus, which connects to the lacrimal sac. The lacrimal sac acts as a temporary reservoir for tears before they flow through the nasolacrimal duct, which ultimately drains into the nasal cavity.
The function of the rivus lacrimalis is to ensure the proper drainage of tears from the eyes, preventing their accumulation and keeping the surface of the eyes moist. Tears also help flush away debris, dust, or foreign particles that may come into contact with the eyes, acting as a protective mechanism. Dysfunction or blockage of the tear duct can lead to a condition called dacryostenosis, causing excess tearing or irritation of the eyes.
A space between the closed lids and the eyeball through which the tears flow to the punctum lacrimale.
