Document Summary

Nervous system anatomy & physiology: central nervous system. Brain and spinal cord: peripheral nervous system. Cerebrum: frontal blue, primary motor, executive functions, parietal yellow, primary sensory, cognitive functions, occipital red, visual processing, temporal- green, primary auditory cortex, language comprehension. Cortex: cortex, formed of neurons, cell bodies of neurons. Grey matter : below cortex, brain, central nervous system (brain and spinal cord, spinal cord, nerve fibers. White matter (myelin sheath: coming from neural cell bodies in cortex, connections, brain regions, sensory information from body to brain, brain signals to muscles. Cortical regions of interest: primary auditory cortex, primary motor cortex, broca"s area, wernicke"s area. In temporal lobe: bilateral, first area of cortex to process auditory information. Awareness or perception of sound: language comprehension nearby. In frontal lobe along precentral gyrus: bilateral. Involved in speech movements: along with cerebellum and subcortical structures (e. g. , basal ganglia, thalamus) Involved in speech production and expressive language: also, role in language comprehension, unilateral.
