Spinal nerves exiting the spinal canal between L4 and S4 collectively make up the sacral plexus.
This typically indicates that there is no obvious compression or narrowing of the central canal or neural foramen at the C2-C3 level of the spine. "Patent" means that these spaces are open and unobstructed. It suggests there are no significant structural abnormalities in this area.
Spinal stenosis is the narrowing of the spinal canal. The spinal canal is the space in your spinal column designed to house and protect the spinal cord. The 7 bones of your neck are known as cervical vertebrae. The narrowing of your spinal canal is most severe at the level of the 4th and 5th cervical vertebrae (C4-5.) Impingement is a term that describes a body structure, usually bone, pushing into either a nerve structure or part of the cord. The cord is divided into ventral, or front, and dorsal, or back. Also the lateral, or side structure are being affected. To sum up, at the level of the 4th and 5th vertabrae of the neck, you have an impingement of the front and side portion of your spinal cord.It means narrowing.
The conus medullaris is the bottom part of the spinal cord. It normally ends at T12 or L1, so you are normal. Below that level, the spinal canal contains a bundle of loose nerves called the cauda equina.

Fatigue decreases the excitatory level of the spinal cord
The spinal cord ends at the level of the first lumbar vertebra, which is just below the level of the ribs.
paraplegia
This appears to be a doctor's diagnosis copied from a medical report. "Prominent central disc extrusion" means that there is a large protrusion or release of the disc material into the central space of the spinal canal. This can be a painful and debilitating problem that could cause pain, weakness and numbness in that part of the body served by that part of the spine. "Mild facet ligamentous hypertrophic changes" means a slight or early increase of size (hypertrophy) of the ligaments surrounding the facet joints of some undetermined area of the spinal column. This is a description of early wear and tear on the spine in which the ligaments are becoming thicker than normal, commonly associated with early degenerative osteoarthritis. "Severe canal stenosis" means a serious and advance degree of closing off or narrowing of the spinal canal. This indicates that the spinal cord is being encroached or pressure is being applied to the spinal cord due to reduction of the diameter of the spinal canal. Taken as a whole, the term means that this person has two problems going on at the same time, disc extrusion and facet ligament thickening, resulting in reduction of the space in the spinal canal. This would likely be causing significant pain, numbness and tingling of the part of the body served by this level of the spine that is being described.
the name of the longest canal in Britain is the Standedge Tunnel canal.
