Posterior ramus syndrome, also referred to as thoracolumbar junction syndrome, Maigne syndrome and dorsal ramus syndrome is caused by the unexplained activation of the primary division of a posterior ramus of a spinal nerve (dorsal ramus of spinal nerve). This nerve irritation causes referred pain in a well described tri-branched pattern. The ...
Some referred pain due to visceral sensations refer to dermatomes that send fibers to the same level of spinal cord. A dermatome is an area of skin supplied by sensory neurons that arise from a spinal nerve ganglion. Symptoms that follow a dermatome (e.g. like pain or a rash) may indicate a pathology that involves the related nerve root ...
Referred pain, also called reflective pain, [1] is pain perceived at a location other than the site of the painful stimulus.An example is the case of angina pectoris brought on by a myocardial infarction (heart attack), where pain is often felt in the left side of neck, left shoulder, and back rather than in the thorax (chest), the site of the injury.
These pathologic changes result in narrowing of the vertebral canal and neurovascular compression at the lumbosacral nerve roots. [1] [18] The compression of these spinal nerve roots that control sensation and movement in the lower body results in the tingling, pain and weakness NC patients often experience. However, because the severity of ...
In humans myotome testing can be an integral part of neurological examination as each nerve root coming from the spinal cord supplies a specific group of muscles. Testing of myotomes, in the form of isometric resisted muscle testing, provides the clinician with information about the level in the spine where a lesion may be present. [7]
The fourth lumbar spinal nerve (L4) [4] originates from the spinal column from below the lumbar vertebra 4 (L4). L4 supplies many muscles, either directly or through nerves originating from L4. They are not innervated with L4 as single origin, but partly by L4 and partly by other spinal nerves. The muscles are: quadratus lumborum; gluteus ...
Spinal nerve Typical spinal nerve location. Each spinal nerve is a mixed nerve, formed from the combination of nerve root fibers from its dorsal and ventral roots. The dorsal root is the afferent sensory root and carries sensory information to the brain. The ventral root is the efferent motor root and carries motor information from the brain.
The course of GVA fibers from organs in the pelvis, in general, depends on the organ's position relative to the pelvic pain line.An organ, or part of an organ, in the pelvis is said to be "above the pelvic pain line" if it is in contact with the peritoneum, except in the case of the large intestine, where the pelvic pain line is said to be located in the middle of the sigmoid colon.
