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.
Neurosyphilis is the infection of the central nervous system in a patient with syphilis. In the era of modern antibiotics, the majority of neurosyphilis cases have been reported in HIV-infected patients. [citation needed] Meningitis is the most common neurological presentation in early syphilis.
Amygdala (limbic system) (limbic lobe) Central nucleus (autonomic nervous system) Medial nucleus (accessory olfactory system) Cortical and basomedial nuclei (main olfactory system) Lateral and basolateral nuclei (frontotemporal cortical system) Extended amygdala. Stria terminalis. Bed nucleus of the stria terminalis; Claustrum; Basal ganglia ...
The autonomic nervous system influences choroid plexus CSF secretion, with activation of the sympathetic nervous system decreasing secretion and the parasympathetic nervous system increasing it. [3] Changes in the pH of the blood can affect the activity of carbonic anhydrase , and some drugs (such as furosemide , acting on the Na-K-Cl ...
The nervous system of vertebrates (including humans) is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). [16] The CNS is the major division, and consists of the brain and the spinal cord. [16] The spinal canal contains the spinal cord, while the cranial cavity contains the brain.
The dorsal column–medial lemniscus pathway (DCML) (also known as the posterior column-medial lemniscus pathway (PCML) is the major sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (body position) from the skin and joints.
These action potentials are conducted to the solitary nucleus in the central nervous system by axons and have a reflex effect on the cardiovascular system through autonomic neurons. [7] Hormone secretions that target the heart and blood vessels are affected by the stimulation of baroreceptors.
Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
