Spinal cord anatomy/structure if we had a stroke in the anterior cerebral artery the le would be a ected on the motor homunculus spinal cord starts once the brainstem exits the foreman magnum and it ends at l1/l2. Functions: conduit function (ascending & descending tracts) Intrinsic function (e. g. re exes) shaped) central gray matter surrounded by ascending and descending white matter columns forms a butter y arrangement: dorsal horn, sensory comes into the cns. Interneurons involved in ans and only exists between t1 and l2. Ventral horn: motor exits the cns contains lower motor neurons project out to the muscles with that segment considered peripheral nervous system. How to tell di erent levels of the sc. Meninges outer layer of dura mater is non existent after the foramen magnum this was the periostyeal layer the epidural space contains fat as a protection for spinal cord subarachnoid space as csf spinal cord ends around.
