Definition

Muhammad A. Javaid

Posterolateral sulcus of spinal cord refers to a sulcus or a groove found on each side of the dorsal (or posterior) surface of the spinal cord. It is situated between the posterior and the lateral white columns. It also serves as the site marking the entry point where the posterior or sensory rootles of spinal nerves attach to the spinal cord. These dorsal rootlets carry sensory information coming from the body to the spinal cord, such as touch, pain, and temperature.
