Lacrimal groove
Lacrimal Groove
The Lacrimal Groove (pronounced: /ˈlækrɪməl/ 'gro͞ov) is a significant anatomical feature of the human skull. It is a part of the Lacrimal bone, which is the smallest and most fragile bone of the face.
Etymology
The term "Lacrimal" is derived from the Latin word "lacrima," which means "tear." The term "Groove" comes from the Old English word "grōf," which means a "furrow, trench, or channel." Hence, the Lacrimal Groove is a channel associated with the tear system of the human body.
Anatomy
The Lacrimal Groove is located on the interior surface of the Lacrimal bone. It forms the beginning of the Nasolacrimal canal, which is responsible for draining tears from the Lacrimal sac into the Nasal cavity.
