2-Minute Neuroscience: Exterior of the Spinal Cord

February 21, 2015

In this video, I cover the exterior of the spinal cord. I discuss how sensory and motor information is carried to and from the cord via dorsal and ventral roots, respectively. I also explain how these roots come together to form spinal nerves, and how a pair of spinal nerves leaves at each segment of the cord; these segments are classified as belonging to cervical, thoracic, lumbar, sacral, or coccygeal regions. Then I describe some major landmarks of the cord, including the conus medullaris, cauda equina, lumbar cistern, and filum terminale.


Sleep. Memory. Pleasure. Fear. Language. We experience these things every day, but how do our brains create them? Your Brain, Explained is a personal tour around your gray matter. Building on neuroscientist Marc Dingman’s popular YouTube series, 2-Minute Neuroscience, this is a friendly, engaging introduction to the human brain and its quirks using real-life examples and Dingman’s own, hand-drawn illustrations.
