PSYCH

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
