Document Summary
Chapter 15 brain and cranial nerves autonomic nervous system notes. Learn in two parts - outside and inner of the brain. Central sulcus (separates the frontal and parietal lobe) Gray matter (inner outside lining of the brain, aka the ends) Synapses - connection between a neuron and another neuron. Nuclei is gray matter outside of the cortex. Myelinated - helps with faster signal speed. Thin layer that attaches to the gray matter, outer lining. Two connective tissues that blood run through. Arachnoid mater goes through the dura mater into superior sagittal sinus. Circulatory system of the central nervous system. Starts inside the cerebral, down into the spinal cord, and back up to the superior sagittal sinus. Cerebrospinal fluid - liquid that fills ventricles and canals. Tissue which separates right and left lateral ventricle. Blood plasma filtered by capillaries and chemically modified by ependymal cells. Median aperture and lateral apertures to subarachnoid space. Brain weighs 1500 g; in csf 50 g.
