Arachnoid
The central canal of the spinal cord or bone is open and unobstructed, allowing for the passage of cerebrospinal fluid or blood vessels. This ensures proper communication and transport of essential substances in the central nervous system.
Cervical spinal stenosis is a narrowing of the spinal canal in the neck region, which can put pressure on the spinal cord and nerves. This can lead to symptoms such as neck pain, weakness, numbness, or tingling in the arms or hands. Severe cases may require surgical intervention to relieve pressure on the spinal cord.
The canal zone is the area that includes the Panama Canal and a 5 mile radius on both sides. It is located in the central part of Panama.
the part of the spinal cord that contains mylinated axons is the White matter portion.
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.
Progressive central canal stenosis at the L3-4 level indicates a narrowing of the spinal canal at this area, which can lead to compression of the spinal cord or nerve roots. This condition is associated with a broad disc protrusion, suggesting that the intervertebral disc is bulging and contributing to the narrowing. Additionally, hypertrophic changes in the facet joints and ligamentum flavum imply that these structures have thickened, further exacerbating the stenosis. Together, these findings can result in symptoms such as pain, numbness, or weakness in the lower extremities.
It is called the central commissure. Some also call it the Grey Commisure.
The skin area along a central nerve pathway is known as a dermatome. Dermatomes are specific regions of skin that are supplied sensation by a single spinal nerve. Each spinal nerve innervates a specific dermatome, allowing for the distribution of sensory information throughout the body.
C-5 to the C-7 area of the spinal cord area.
The central plateau is a flat, elevated area of land located in the interior of a continent. It is generally characterized by its high elevation, relatively flat terrain, and may be surrounded by higher mountain ranges. The central plateau often experiences cooler temperatures and can be an important agricultural region due to its fertile soils.
The area of Petit-Canal is 72 square kilometers.
