Bilateral split sciatic nerve. Magnetic resonance neurography (MRN) is the direct imaging of nerves in the body by optimizing selectivity for unique MRI water properties of nerves. It is a modification of magnetic resonance imaging. This technique yields a detailed image of a nerve from the resonance signal that arises from in the nerve itself ...
Once the spinal injury has occurred, one of two things may happen. Firstly, hemorrhaging within the spinal cord may cause compression, which damages the spinal cord even further. Another consequence of myelomalacia is improper circulation of blood to the area damaged, resulting in further damage to the spinal cord. [citation needed]
Other areas of the nervous system that have been affected are the phrenic nerves and the recurrent laryngeal nerve. As the nerves lose function, the muscles associated with those nerves begin to atrophy. In brachial plexus degeneration, atrophy may occur in the deltoid muscles. In phrenic nerve degeneration, the diaphragm may be affected.
To confirm the identity of the phrenic nerve, a doctor may gently manipulate it to elicit a dartle (diaphragmatic startle) response. [7] The right phrenic nerve may be crushed by the vena cava clamp during liver transplantation. [8] Severing the phrenic nerve [9] will paralyse that half of the diaphragm. Bilateral paralysis can be caused by ...
Often, the brain is able to compensate for some of this damage, due to an ability called neuroplasticity. MS symptoms develop as the cumulative result of multiple lesions in the brain and spinal cord. This is why symptoms can vary greatly between different individuals, depending on where their lesions occur.
Various kinds of tumors, usually primary and benign, are represented in the pathology. Lesions in the area of cerebellopontine angle cause signs and symptoms secondary to compression of nearby cranial nerves, including cranial nerve V (trigeminal), cranial nerve VII (facial), and cranial nerve VIII (vestibulocochlear). The most common ...
When immune cells attack the myelin sheath, this causes inflammation and interrupts the passage of nerve impulses around the body, leading to neurological symptoms which may include: Muscle ...
Transverse myelitis (TM) is a rare neurological condition wherein the spinal cord is inflamed.The adjective transverse implies that the spinal inflammation extends horizontally throughout the cross section of the spinal cord; [1] the terms partial transverse myelitis and partial myelitis are sometimes used to specify inflammation that affects only part of the width of the spinal cord.
