Cuneate tubercle

One method of cell organization is the nuclei, which is a cluster of neurons closely located to each other. It appears as gray matter, often surrounded by white matter. The dorsal column nuclei are located in the brain stem. One of the primary dorsal column nuclei of the brain stem forms the cuneate tubercle. As a general term in anatomy, tubercle refers to a small outgrowth or round nodule found within or on the body or in an organ. When the brain stem is viewed from below, it appears to have a series of bumps on its surface. These bumps (tubercles) contain nuclei. The cuneate tubercle is located within the cuneate nucleus, which is shaped like a wedge. It is a component of the dorsal column medial-lemniscus system. This system transfers sensory information regarding vibration, fine touch and proprioceptive information from the upper body to the brain. Proprioceptive information is internal knowledge of how the body is moving and where the body parts are in relation to the other body parts. The specific area of responsibility of the neurons contains within the cuneate tubercle is above the sixth thoracic vertebrae, but does not include the face or the ear.
