cerbral cortex
outermost layer of the brain, controls high level mental processes such as thought
depression marking off an area of the cerebral cortex
one half of the cerebral cortex each half controls the opposite side of the body
corpus callosum
large bundle of nerve fibers that transfer information from one half of the cerebral cortex to the other
major divisions of the cerebral cortex
frontal lobe
division of the cerebral cortex that contains the motor strip, prefrontal area, and frontal association area
parietal lobe
division of the cerebral cortex that contains the sensory strip
motor strip
band running down the side of the frontal lobe that controls all bodily movements
sensory strip
band running down the side of the parietal lobe that registers and provides all sensation
occipital lobe
division of the ceebral cortex that interprets visual information
temporal lobe
division of the cerebral cortex responsible for hearing and some speech functions
profrontal area
part of the frontal lobe that enables us to reexperience personal past events
frontal association area
part of the frontal lobe that engages in elaborate associations or mental connections it plays an important part in integrating personality and in forming complex thoughts
control, either the right or left hemisphere of the cerebral cortex is dominantin each individual; hence one of them is preferred and controls the majority of actions performed
lower brain
part of the brin common to animals and humans that regulates basic functions such as breathing
part of the lower brain that functions primarily as a central relay station for incoming and outgoing messages from the body to the brain and the brain to the body

the alertness control center of the brain that regulates the activity level of the boy also called the reticular formation
a nerve cell neurons transmit electrical and chemical information throughout the body
part of neurons that recieve information from the axons of other neurons
part of the neuron that carries messages away from the cell to the dendrites on another neuron
the junction point of two or more neurons; a connection is made by neurotransmitters
bubblelike containers of neurotransmitters, located at the ends of axons
chemicals in the endings of neurons that send information across the synapses
neurotransmitter that regulates basic bodily processes such as movement

neurotransmitters that relieve pain and increase our sense of well being
central nervous system
brain and spinal cord
spinal cord
part of the body that functions as an autonomic brain in its own right and as a relay station for impulses to and from the higher brain
an autonomic behavior of the body involving movement that is activated throught the spinal cord without the use of a higher brain
paripharl nervous system
all the nerves outsidethe brain and spinal cord
somatic nervous system
a division of the paripheral nervous system containing sensory and motor nerves
autonomic nervous system
autonomic control system of the body reglulates breathing, heart rate, digestion, and so on
sympathetic nervous system
a division of the autonomic nervous system that energizes and prepares for emergencies
parasympathetic nervous system
a division of the autonomic nervous system that conserves bodily activity; works in oppisition to the sympathetic ystem to calm us down
chemical regulators that control bodily processes such as emotional responses, growthm and sexuality
units of the body that contain the hormones
endocrine system
system that includes all the gland and their chemical messages taken together
pituitary gland
