What does the parietal lobe control?

integrates sensory information

superficial to deep, what are the structures of the brain?

lobes, cerebellum, white matter tracts, and brainstem

What is the peripheral nervous system?

nerves the branch from the CNS and innervate the rest of the body

What does the frontal lobe control?

personality and motor function

What does the hypothalamus control?

regulate body temperature and other things

What is the basal ganglia?

releases many of the chemicals the neurons use to communicate

What is the sympathetic nervous system?

responsible for fight or flight

What is the reticular activating system?

series of white matter tracts that interconnect various parts, a network of nerves that connect the different pathways in the brainstem, and spinal cord

What does the temporal lobe control?

speech and memory

What are the two subdivisions of the autonomic nervous system?

sympathetic system and parasympathetic system

What does white matter do?

the "highways" of the brain, connect parts of the brain and are vital for consciousness

What is the autonomic nervous system?

the "unconscious" system, controlling the function of most organs and vital bodily processes

during stress what happens to the autonomic nervous system?

the sympathetic nervous system (fight or flight) overrides the parasympathetic (rest and digest) system

What does the occipital lobe control?

visual stimuli

what are the two subdivisions of the peripheral nervous system?

autonomic and somatic

What does the central nervous system consist of?

brain and spinal cord

What does the brain stem control?

breathing, heart rate, blood pressure

what are the two divisions of the nervous system?

central nervous system and peripheral nervous system

What is the somatic nervous system?

commonly called the "skeletal/muscular" system, as it is responsible of the control of all voluntary movement

what are the three things the central nervous system is responsible for?

consciousness, major interpreting of stimuli from sensory organs, and coordinating hormonal responses to stimuli (fight and flight)

What is the parasympathetic nervous system?

decreases energy use and prioritizes digestion, so it is called the "rest and digest" response

What does the cerebellum control?
