Document Summary
Disease or disorder results from damage to neurons and/or glia. Neurons: cells responsible for signal transmission (receive, conduct, and send signals) Provide support, insulation, nutrition, control, homeostasis, form myelin for neurons, remove pathogens. Within skeletal casing skull, spinal column. Cortex, centers, nuclei cell bodies gray matter. Tracts, columns axons white matter. Outside skeletal casing: made up of: somatic ns, ans, enteric ns. Ganglia cell bodies gray matter. Fibre tracts (ascending/descending) pathway passing up and down peripheral nerves//spinal cord to supraspinal regions: nuclei involved in homeostasis (regulation) Highly organized region with inputs and outputs through the brain stem. Important in control of movement, learning and non-motor activities. Groups of nuclei connected to cortex, thalamus and brain stem: putamen, caudate, globus pallidus, subthalamic nucleus, substanti nigra. Important in contribution to control of movement, learning, cognition and emotions. Extensive connection to and from other cns regions. Cell body located in the spinal cord or brainstem.
