A nerve root diverticula is an abnormal outpouching of the spinal nerve root sleeve, which is the covering of the nerve roots as they exit the spinal cord. This can sometimes cause irritation or compression of the nerve root, leading to symptoms such as radiating pain or weakness. Treatment may involve rest, physical therapy, or in some cases, surgery to relieve the pressure on the nerve.
The plural is diverticula.
Nerve root abutment refers to the compression or irritation of a nerve root as it exits the spinal column. This can be caused by conditions such as a herniated disc, spinal stenosis, or degenerative changes in the spine. Symptoms can include pain, weakness, or numbness in the affected area supplied by the nerve.
The ventral root of the spinal nerve has the efferent fibers and the dorsal root has the afferent. Prior to joining each other in the spine they each consist of only those fibers.
I believe this hasn't been answered as it is a typo; they probably meant to write sciatic nerve, or ischiatic nerve is composed of L4-S3 spinal and anterior and posterior divisions of the lumbosacral plexus.
Nerve root ectasia refers to the abnormal enlargement or dilation of a nerve root, typically occurring in the spinal column. This condition can result from various factors, including compression from adjacent structures, inflammation, or injury. Symptoms may include pain, numbness, or weakness in the areas served by the affected nerve root. Diagnosis is often confirmed through imaging studies such as MRI or CT scans.
Diverticula
diverticula
diverticula is the plural of diverticulum.
Spinal nerve.....
The Greek root meaning nerve is "neur" or "neuro", which is commonly used in words related to the nervous system or nerve function.
Nerve root effacement refers to nerve root compression. This is an issue where the root of the nerve is compressed into the spine before exiting it, which can cause some painful back symptoms.
The root word meaning "nerve" is "neur-" from the Greek word "neuron" meaning sinew or nerve.
Neur- is the word root for neuritis, meaning inflammation of a nerve.
The plural is diverticula.
"Diverticulum" is the singular of diverticula.
Larger diverticula, termed giant diverticula, are quite infrequent, but may measure as large as 15 cm in diameter
Vagotomy is the medical term meaning surgical incision of the vagus nerve.
