Document Summary
Neuron: basic unit of the nervous system, consists of 3 parts. Synapse: exchange of information from axon of one neuron to the dendrite of another through electrochemical impulses. The brain consists of: cerebrum, cerebellum, brainstem. Cerebrum: largest part of human brain, consists of 2 hemispheres (halves) Each hemisphere controls the opposite side of the body. Occipital lobe: the cerebrum has a wrinkled appearance because of. Separates the cerebrum into right and left hemispheres: central sulcus/fissure of rolando. Separates the frontal lobe from the parietal lobe: lateral sulcus/fissure of sylvius. Separates the frontal lobe from the temporal lobe. Controls sense of touch, temperature, pressure, and positions of body. Temporal lobe: primary auditory area (auditory cortex, wernicke"s area. Cerebellum: attached to the brainstem, regulates and coordinates movement of the body, also involved in language processing and higher-level cognitive functions. Brainstem: processes incoming and carries messages between the brain and the rest of the body, midbrain.
