The foramen is the portal in the vertebra where the spinal cord branches out into nerves that run to other parts of the body. Narrowing can constrict this nerve, which in turn can result in pain, numbness and in more extreme cases, loss of motor control -- it may also be asymptomatic. C3 is the third cervical vertabra -- that would be in your neck.
what is disc protrusion in the right neural foramen abutting right L5 nerve root
narrowing of the right opening through which the nerve passes
neurol foraminal right narrowing c4-5 mild moderate can it be serious?
There's something crowing the space (encroaching) in the bony hole that allows passage of the nerve (foramen) between the third and fourth and the fourth and fifth vertebrae in the neck.
Foraminal encroachment refers to that degeneration in the spinal column which causes the obstruction of the foramina.
This sounds like someone reading an MRI report. It basically is arthritic changes with ageing
This means that the spinal disc ("shock absorber" between the vertebrae) is protruding (bulging) on the left into the area where the peripheral spinal nerve leaves the spinal cord (neural foramen). If the disc compresses (impinges) the spinal nerve in the neural foramen, there can be symptoms that radiate into the extremities. If the nerve impingement is in the neck, then symptoms are usually felt in the shoulder blade area and arm. In the low back, the symptoms can be felt in the buttock and back of the thigh ("sciatica") and even the entire leg and foot.
A herniated disc in the low back which makes the foramina (the bony holes on either side through which the spinal nerves pass) narrow. This can result in one or both of the spinal nerves being pinched, causing pain or numbness to radiate down one or both legs. On the other hand, it's possible that neither nerve is pinched at all.
Moderate right foraminal narrowing at C5-6 is narrowing of the canals in the spine. C5-6 stands for cervical number 5 and number 6.
"Stenosis"
A Patent (Open) Foramen Ovale bypasses the lungs by short circuiting blood flow from the right atrium to the left atrium.
One can find more information about Foramen Ovale from the Mayo Clinic website. The Foramen Ovale is located within the fetal heart and it allows blood to enter and move through the left atrium after the right.
