Navicular
Navicular (pronunciation: /nəˈvɪkjʊlər/) is a term used in anatomy to describe a bone found in humans and some other animals. The term is derived from the Latin word "navicula", which means "little ship".
Human Anatomy
In human anatomy, the navicular bone is found in the foot. It is one of the tarsal bones, located on the medial side of the foot, and articulates proximally with the talus, distally with the three cuneiform bones, and laterally with the cuboid.
Horse Anatomy
In horses, the navicular bone is a small, boat-shaped bone found within the hoof, behind the coffin bone and the short pastern bone. It plays a crucial role in the horse's locomotion.
