Accessory cuneate nucleus

Accessory cuneate nucleus is a small, oval-shaped structure located in the lateral part of the medulla oblongata, a region of the brainstem. It is also known as the external cuneate nucleus.

Anatomy

The accessory cuneate nucleus is situated lateral to the cuneate nucleus and medial to the spinal trigeminal nucleus. It is a part of the dorsal column-medial lemniscus pathway, which is responsible for transmitting fine touch and proprioceptive information from the body to the brain.

Function

The accessory cuneate nucleus receives input from the cuneocerebellar tract, which carries proprioceptive information from the upper body. This information is then relayed to the cerebellum, which uses it to coordinate and regulate motor movements.

Clinical significance

Damage to the accessory cuneate nucleus can result in loss of proprioception and fine touch sensation in the upper body. This can lead to difficulties with balance and coordination, as well as a decreased ability to perceive the position of the body in space.
