Lingula of cerebellum

The Lingula of Cerebellum is a small, tongue-shaped process, and is the most anterior part of the superior vermis. It is a part of the cerebellum, which is a region of the brain that plays an important role in motor control. The lingula receives input from the spinal cord, and is involved in the coordination of movements, particularly those that are rapid and automatic.

Structure

The lingula is located in the anterior lobe of the cerebellum, just above the primary fissure. It is a thin, flat structure, and is separated from the central lobule by the precentral fissure. The lingula is composed of several folia, which are thin layers of grey matter that are folded to increase the surface area of the cerebellum.

Function

The lingula is involved in the coordination of movements, particularly those that are rapid and automatic. It receives input from the spinal cord, and sends output to the deep cerebellar nuclei, which in turn send signals to other parts of the brain and spinal cord to coordinate movements.

Clinical significance

Damage to the lingula can result in a variety of motor disorders, including ataxia, which is a lack of coordination and balance. In addition, lesions in the lingula can cause dysmetria, which is a lack of control over the range of movement in a muscle.
