recieve messages from neurons and send to cell body
Denrites
holds & produces the energy to fuel nueron activity
cell body
long fibers carring message to dendrite of next neuron
Axon
white fatty acid that insulates & protects
myelin sheath
space between 2 neurons
synapse
send the message through synapse to the dendrites
axon termanals
where info comes from
nucleus
chemical messages
neuron transmitters
send messages althrough our nerves
nuerons
brain and spinal cord controls all movment
central nervous system
somatic and autonomic nervous system
peripheral nervous system
controls voluntary muscles
Somatic nervous system
controls invoultary muscles
Autonomic nervous system
expands energy
sympathetic
conserves energy
parasympathetic
nerves that run up and down the length of the back and transmit most maessages between the body and brain
spinal cord
-located at the rear base-a part of the brain located at the rear base of the skill that is involved in the basic processes of lifeEX: waking up
hindbrain
-located above the pons-a small part of the brain above above the pons that integrates sensory information and relays it upwardEx: sense sensory
midbrian
-the rest of the brain that covers the central core-a part of the brain that covers the brains central core consists of left and right hemispheres which are connected by a wide band of fibers the corpus callosum
forebrain
the differnt regions into which the cerebral cortex is dividedEx: occipatal lobe- vision
lobes
-measures brain activity-a machine used to record the electrical activity of large portions of the brainEx: activity of neuron when sleeping
electroencephalograph (EEG)
-shows brain stucture-X-ray of brian-an imaging technique used to study the brain to pinpoint injury and brian deteriorationEx: when you get hit by a football
computerized axial tomography (CAT)
-patients drink radio active glucose and image shoes areas of brain activity-an imaging technique used to see which brain areas are bieng activated while performing tasksEx: when speaking or thinking
position emmision tomography (PET)
An imaging technique used to study brain structure and activityEx: to view the brain
Magnetic resonace imaging (MRI)
a chemical comunnication system using horomones by which messages are sent through the bloodstream Ex: horomones/ bloodstream body fluids
endocrine system
chemical substances that carry messages through the body in bloodEx: pituitary gland adrenal medulla
horomones
the center control of the endocrine system that secretes a large number of hormonesEx: master gland/ Growth
pituitary gland
-located in the hind brain-helps control posrture balance voluntary movements
cerebellum
-located in the hind brain-function as bridge from brain to spinal cord-produces chemical for sleep
pons
-located in the hindbrain-controls breathing, heart rate, & a veriety of reflexes
medulla
-located in the midbrain-intergrates sensory information and relays it upwards-serves to alert the rest of the brian to incoming signals and is involved in the sleep/wake cycle
retcular activating system (RAS)
-located in the forebrain-intergrates sensory input, relay station for all information from the cortex
thalamus
-located in the forebrian-controls hunger, thirst, sexual behavior, body reactions to change in temp
hypothalamus
-located in the forebrain-ability to learn & store complex & abstract information project, our own thinking to the future
cerebral cortex
-located in the forebrain-controls sight of conscious thinking process
cerebrum
-located in the forebrian-regulates emotion and motavation
limbic system
-located in the forebrain-controls emotions
amygdalla
-located in the very rear-is for vision
occipital lobe
-mid way between front and rear-deals with body sensation
parietal lobe
-located in the front of brian-planning of movements, working movements, working memory, organization, planing & creative thinking
frontal lobe
-located on the side of brain-deals with hearing
temporal lobe
process info wholistically look at the big picture not details-random jump task task -decision are based on feelings-know what you mean but might have difficulty expressing it-creative
triats of right brian person
think more linear-logical-process info in sequences-tends to be comfortible w/ linguistic and math-having little of no trouble expressing themselves in words-reality based: focus on rules
triats of left brain
