-
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 life
EX: waking up
hindbrain
-
-located above the pons
-a small part of the brain above above the pons that integrates sensory information and relays it upward
Ex: 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 divided
Ex: occipatal lobe- vision
lobes
-
-measures brain activity
-a machine used to record the electrical activity of large portions of the brain
Ex: 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 deterioration
Ex: 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 tasks
Ex: when speaking or thinking
position emmision tomography (PET)
-
An imaging technique used to study brain structure and activity
Ex: 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 blood
Ex: pituitary gland adrenal medulla
horomones
-
the center control of the endocrine system that secretes a large number of hormones
Ex: 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
