White matter is composed of bundles, which connect various grey matter areas (the locations of nerve cell bodies) of the brain to each other, and carry nerve impulses between neurons. Myelin acts as an insulator, which allows electrical signals to jump , rather than coursing through the axon, increasing the speed of transmission of all nerve ...
The lumbar cistern is part of the subarachnoid space.It is the space within the thecal sac which extends from below the end of the spinal cord (the conus medularis), typically at the level of the first to second lumbar vertebrae down to tapering of the dura at the level of the second sacral vertebra.
Pia mater (/ ˈ p aɪ. ə ˈ m eɪ t ər / or / ˈ p iː ə ˈ m ɑː t ər /), [1] often referred to as simply the pia, is the delicate innermost layer of the meninges, the membranes surrounding the brain and spinal cord.
A deficiency in GALC thus causes a buildup of these fatty acids, leading to an incursion by cells called "globoid macrophages" that destroy oligodendrocytes, thereby inhibiting any further myelin formation. [20] Given the presence of globoid macrophages clustered near white matter, Krabbe disease often is called globoid cell leukodystrophy.
The cerebral cortex, also known as the cerebral mantle, [1] is the outer layer of neural tissue of the cerebrum of the brain in humans and other mammals.It is the largest site of neural integration in the central nervous system, [2] and plays a key role in attention, perception, awareness, thought, memory, language, and consciousness.
The dentate nucleus becomes visible in the cerebellar white matter as early as 11–12 weeks of gestation, containing only smooth lateral (towards the side(s) or away from the midline) and medial (towards the midline) surfaces. During this time, the neurons of the dentate nucleus are similar in shape and form, being mainly bipolar cells. [2]
The primary cells of cartilage are chondrocytes, which are in a matrix of fibrous tissue, proteoglycans and glycosaminoglycans. [ 2 ] [ 3 ] As cartilage does not have lymph glands or blood vessels, the movements of solutes, including nutrients, occur via diffusion within the fluid compartments contiguous with adjacent tissues.
