Limbus
Limbus
Limbus (pronunciation: /ˈlɪmbəs/) is a term used in various fields of medicine, particularly in ophthalmology and anatomy.
Etymology
The term "limbus" is derived from the Latin word for "border" or "edge". In a medical context, it often refers to a border or transitional zone between two areas.
Ophthalmology
In Ophthalmology, the limbus is the border area where the cornea meets the sclera, the white part of the eye. This region is rich in stem cells that help in the regeneration of the cornea. It also plays a crucial role in maintaining the clarity of the cornea by preventing the overgrowth of the conjunctiva, the clear tissue covering the white part of the eye.
Anatomy
In general Anatomy, limbus can refer to the border or edge of any structure. For example, the limbus of the femur refers to the edge of the head of the femur bone.
