The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.
A very important type of glial cell (oligodendrocytes in the central nervous system, and Schwann cells in the peripheral nervous system) generates layers of a fatty substance called myelin that wraps around axons and provides electrical insulation which allows them to transmit action potentials much more rapidly and efficiently. Recent findings ...

The somatic nervous system's principal goal is to facilitate the organs and striated muscles of the central nervous system so that we can carry out our daily responsibilities. The primary motor cortex, or precentral gyrus, is home to the higher motor neurons that make up the basic motor pathway. These neurons transmit signals to the lower motor ...
Layers of the Alimentary Canal.The wall of the alimentary canal has four basic tissue layers: the mucosa, submucosa, muscularis, and serosa. The enteric nervous system in humans consists of some 500 million neurons [11] (including the various types of Dogiel cells), [1] [12] 0.5% of the number of neurons in the brain, five times as many as the one hundred million neurons in the human spinal ...
The 11th plenary session of the eighth central committee of the Workers' Party of Korea wraps up a year in which Russian President Vladimir Putin held a summit with Kim and signed a deal that ...
However, their real connection formed thanks to the 2022 Broadway revival of The Music Man, in which Jackman starred as Professor Harold Hill and Foster portrayed Marian Paroo.. Both stars were ...
These tracts are in turn modulated by various parts of the central nervous system, including the nigrostriatal pathway, the basal ganglia, the cerebellum, the vestibular nuclei, and different sensory areas of the cerebral cortex. All of these regulatory components can be considered part of the extrapyramidal system, in that they modulate motor ...
