Note cards as study cards!!!
Hemisphere Dominance
Brain
hemisphere that
person uses mostexcels in hemisphere
skills
Motor cortex

On each hemisphere, controls
movement
Sensory Cortex

On each hemisphere, controls touch
Occipital lobe

Back of the brain, processes sight
Frontal cortex


Judgement, personality
The larger it is the more sophisticated
the species
Left Hemisphere

Language, logic
Right Hemisphere

Spatial, creativity, face recognition
Corpus callosum

Neural cables connecting the left and
right hemispheres
Cerebral cortex

Upper brain- controls all human
functions, example—thinking, personality
Lower Brain

Controls non- thinking processes
example- heart rate, temperature
Hemispheres

Cerebral cortex divided into 2 parts– left
and right
cerebellum

Lower brain part– controls balance
Hypothalamus

Controls basics such as hunger and
thirst
Central nervous system

Consists of the brain and the spinal
column
Thalamus

Relays messages to the brain to the part
to be processed
Pituitary gland

Master gland– controls growth
Neurons

Individual brain cells
Neural pathway-
One way communication axon –
synapse-- dendrite
Synapse

Space between neurons
Axon
Sends message across synapse to next
neuron
Dendrite
End of neuron that receives message
Endocrine system

Chemical messenger system of brainglands and hormones
RAS

Located in brain stem- regulates
alertness
Reflex

Lowest form of behavior– spinal column
deals with them
Thyroid gland

Controls metabolism
Hormones

Produced by glands
neurotransmitters

Chemicals in the brain– ex. histamine
Gage

Accident that proved different functions
for different brain parts
Adrenal glands

Send extra strength hormones to
muscles
