The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain, spinal cord and retina.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 ...
La dinámica en el sistema nervioso. Estructuras sensoriales por sincronización cerebral (Research on Brain Dynamics. Dynamics in the nervous system. Sensory structures by brain synchronization), which was awarded by this organism that same year. During the years 1942–1944, established in Madrid and sponsored by the Cajal Institute, he ...
The foreshortening of the central sulcus has been found to be an abnormality associated with this syndrome. [14] This can be seen with the abnormal dorsal end of the central sulcus in individuals with Williams syndrome. [14] However, the abnormal dorsal end of the central sulcus has not been found to be linked to impaired general intelligence. [14]
Central nervous system (CNS) depression is a physiological state that can result in a decreased rate of breathing, decreased heart rate, and loss of consciousness, possibly leading to coma or death. It is the result of inhibited or suppressed brain activity .
Primary central nervous system lymphoma (PCNSL), also termed primary diffuse large B-cell lymphoma of the central nervous system (DLBCL-CNS), [2] is a primary intracranial tumor appearing mostly in patients with severe immunodeficiency (typically patients with AIDS). It is a subtype and one of the most aggressive of the diffuse large B-cell ...
The brain and spinal cord of the central nervous system are connected with organs that have smooth muscle, such as the heart, bladder, and other cardiac, exocrine, and endocrine related organs, by ganglionic neurons. [8] The most notable physiological effects from autonomic activity are pupil constriction and dilation, and salivation of saliva. [8]
