Cingulum
Cingulum
Cingulum (/sɪŋˈɡjuːləm/; from Latin cingulum meaning "girdle") is a term used in various fields of medical science.
Anatomy
In anatomy, the cingulum refers to a bundle of white matter fibers projecting from the cingulate gyrus to the entorhinal cortex in the brain. It forms an integral part of the limbic system, which is involved in emotion formation and processing, learning, and memory.
Dentistry
In dentistry, the cingulum is a convex area on the lingual surface of a tooth, particularly the upper anterior teeth, located at the cervical third of the crown. It is named for its encircling, girdle-like position at the base of the crown.
Etymology
The term "cingulum" is derived from the Latin word cingulum which means "girdle". This is in reference to the encircling position it occupies in the brain's limbic system and at the base of a tooth's crown in dentistry.
