Improved imaging methods have provided new in vivo evidence for the role of spinal cord grey matter atrophy in multiple sclerosis (MS): two recent studies suggest that loss of spinal cord grey matter is the main contributor to progressive disability. Post-mortem studies have identified extensive ...
Definition Grey matter is a form of tissue found in the brain and spinal cord that contains neuronal cell bodies and capillary. Description Grey matter is a form of tissue found throughout the Central Nervous System . It is so termed based on its characteristic grayish-brown color. Grey ...
英文:In neurodegenerative diseases, grey matter is often affected. 英文同义表达: Gray matter:与'grey matter'意思相同,只是拼写上的差异,均指灰质。 Cerebral gray matter:特指大脑的灰质部分,更具体地描述了灰质的位置。 Neuronal cell bodies in the brain and spinal cord:这是一...
Lepidoptera spinalis Grey matter butterflies in spinal cord cross-sections. The spinal cord is composed of a peripheral region of “white matter” that contains the many axons of neurons as they e...
Spinal cord MRI suggests that grey matter atrophy in the thoracic cord is an important source of disability in patients with multiple sclerosis (MS). Regina Schlaeger and colleagues imaged multiple levels of the cervical and thoracic spinal cords of patients with relapsing or progressive MS....
Grey matter definition: the greyish tissue of the brain and spinal cord, containing nerve cell bodies, dendrites, and bare (unmyelinated) axons. See examples of GREY MATTER used in a sentence.

These myelinated axons speed up the transmission of electrical signals between neurons, enabling efficient communication across different parts of the brain and spinal cord. 6 The distribution of grey and white matter varies throughout the brain. Grey matter is densely packed with neuron cell bodies...
The ultrastructural changes of the microvasculature in the spinal grey matter were studied after impact injuries of varying severity in cats. Survival times ranged from 3 min to 6 h after injuries. The main vessels affected were capillaries and postcapillary venules. Perivascular haemorrhage and prote...
The middle cells are present throughout the whole length of the spinal cord. They are situated in the middle region of the grey matter, between the free anterior and free posterior cornua; but they sometimes also extend into the regions usually occupied by the anterior cornual cells, by the...
