L7: Paraplegia Flashcards
Where Does Spinal Cord Begin?
at the level of the foramen magnum.
Where Does Spinal Cord End?
- at the level of the lower border of L1 vertebra.
Its terminal part is called conus medullaris (S 3, 4, 5).
Spinal Cord Segments
Each segment has on each side a ventral & a dorsal root
- join together just distal to the dorsal root ganglion to form spinal nerve that emerge from corresponding foramen.
Cauda Equina
All the roots of the spinal nerves from L2 to the lowest coccygeal nerve pass in the subarachnoid space.
The Spinal Cord is surrounded by ……
