The posterior horn, also referred to as the dorsal horn, is a specific region in the spinal cord. This area is responsible for relaying sensory information to the brain, processing touch, temperature, and pain. Other synonyms for the posterior horn include the dorsal column, dorsal root, and dorsal column-medial lemniscus pathway. Understanding the different terminologies used to describe this region is important in medical fields such as neurology and orthopedics. Medical professionals may also use additional terms to pinpoint specific areas within the posterior horn, such as the lateral horn or ventral horn. Proper terminology helps ensure accurate communication and diagnosis between medical professionals and their patients.
