Spinal cord and cauda equina. Note that the spinal cord ends at about L1, with the conus medullaris. Nerve roots travel further down as the cauda equina. Their relative mobility within the cerebrospinal fluid decreases the risk of neural damage with subarachnoid injections done at the L4 level.
General overview Ascending tracts Sensory Descending tracts Motor General arrangement of both tracts 1st order neuron 2nd order neuron 3rd order neuron The only difference is the different locations where each order of neuron ends. Decussation is the cross-over of the tract from one side to the other. Therefore, there are instances where the left…
Cross-Sectional Anatomy of the Spinal Cord. (a) Relationships to the vertebra, meninges, and spinal nerve. (b) steal of the spinal cord, meninges, and spinal nerves, (c) cross section of the liar spinal cord with spinal nerves The spinal cord and brain are enclosed in three fibrous membranes called meninges. They separate the soft tissue of the CNS from the bones of the vertebrae and skull. From superficial to deep, they are the dura mater, arachnoid mater, and pia mater
