I'm looking for explainations on the lamina in the spinal cord. Thank you?
The word"lamina" in connecion with "LAMINECTOMY".
The lamina is part of the ring of bone that surrounds the spinal cord (and the sac of nerve roots below the spinal cord - the cord ends about the L1 level in an adult and below that are nerves, but not actually spinal cord)
Here's a link to a picture:

The lamina can be removed in part, or completely, depending on the patient's condition. E.g.
Completely removed to make the ring of bone (an O) into a "C" by removing the lamina - which is the back part of the bony ring. This makes more room for the spinal cord or nerves if they are being compressed. Sometimes the lamina is removed to reach the nervous tissue for other reasons too, such as removing a spinal tumor.
Removed in part, aka a hemilaminectomy (one side or the other) to remove a herniated disc that is pressing on a nerve and causing leg pain.
