Which cerebral white matter structure conducts nerve impulses between gyri in different hemispheres o?
association tracts
What is gray matter white matter how does the arrangement of gray and white matter differ in the cerebral hemispheres?
Gray matter is mainly densely packed nerve cell bodies and comprise the outer layer of the cerebrum. White matter is mainly axons surrounded by myelin and are the inner layer of the cerebrum.
What is the ICD-10 code for periventricular white matter lesion?
Dx Code - 348.8
Function of white matter in the brain?
The white matter is the area of the brain where signals travel to other parts of the brain. It is located in the subcortical area.
Why is the cerebellum called the mini brain?
It's seperate from the cerebral hemispheres, sitting just under them. It has a similar simplified structure in that it is highly folded with a grey matter cortex and a white matter core. It has also been linked in many cognitive functions, but it's most researched is its role in movement.
What is mild diffuse cerebral and cerebellum volume loss and T2 hyperintesnity within the periventricular white matter?
Mild diffuse cerebral and cerebellum volume loss and T2 hyperintensity within the periventricular white matter refers to a stroke. This can cause a slight decrease in the white matter of the brain.
What is multiple small hypo densities seen in bilateral fronto-parietal subcortical and periventricular white matter?
Small hypo densities are seen in bilatereral para ventricular region
Bands of white matter that join the right and left cerebral hemispheres?
corpus callosum
What type of white matter fiber tract connects the two cerebral hemispheres?
commissures
What does it mean the brain parenchyma shows periventricular T2 hyperintensity and a few scattered subcortical foci of increased T2 and flair signal intensity in the frontal lobes that are nonspecifi?
what does this mean? Impression: There are scattered foci of T2/FLAIR hyperintensity within the periventricular, deep and subcortical white matter. The findings are nonspecific but may be seen in mild to moderate small vessel ischemic changes. No evidence for acute infarct or hemorrhage.
Which cerebral white matter structure conducts nerve impulses between gyri in different hemispheres o?
association tracts
What is the white matter that lies beneath the cerebral cortex?
the corpus callosum. it also connects the brain's two hemispheres.
If decorticate posturing is present the lesion is?
Anatomic location of the lesion would be below the cortex, in the white matter or the cerebral hemispheres or upper part of the brain stem.
What is gray matter white matter how does the arrangement of gray and white matter differ in the cerebral hemispheres?
Gray matter is mainly densely packed nerve cell bodies and comprise the outer layer of the cerebrum. White matter is mainly axons surrounded by myelin and are the inner layer of the cerebrum.
What is the gray matter on the surface of the brain called?
Grey matter is distributed at the surface of the cerebral hemispheres (cerebral cortex) and of the cerebellum (cerebellar cortex), as well as in the depths of the cerebrum (thalamus; hypothalamus; subthalamus, basal ganglia - putamen, globus pallidus, nucleus accumbens; septal nuclei), cerebellar (deep cerebellar nuclei - dentate nucleus, globose nucleus, emboliform nucleus, fastigial nucleus), brainstem (substantia nigra, red nucleus, olivary nuclei, cranial nerve nuclei) and spinal grey matter (anterior horn, lateral horn, posterior horn).
What are the folds on the cerebral hemispheres?
The folds on the cerebral hemispheres are called gyri, which are the raised ridges on the brain's surface. The grooves separating the gyri are called sulci. These folds increase the surface area of the brain, allowing for more neurons and connections to be packed into a smaller space.
What is the ICD-10 code for periventricular white matter lesion?
Dx Code - 348.8
