function of frontal lobe - answer The executive, behavior, Personality and emotional
expression, motor Control
Associated with higher order of intellectual activity
If injured - need to learn how to read again

field, motor speech area (Broca's area)

of producing speech NOT cognitive area
precentral gyrus - answerthe strip of frontal cortex, just in front of the central sulcus, that
is crucial for motor control

information about touch.
parietal (cerebral lobe) - answersomatosensory processing area and Gustatory area
gustatory cortex - answerarea of the brain that receives and interprets tastes from the
tongue
temporal (cerebral lobe) - answerA region of the cerebral cortex responsible for hearing
(auditory cortex), gustatory area and olfactory area
Occipital lobe (cerebral lobe) - answerVisual cortex
Speech areas of brain - answerSpan temporal, parietal and occipital lobes (usually left

Nerves - answerneural "cables" containing many axons. These bundled axons, which
are part of the peripheral nervous system, connect the central nervous system with
muscles, glands, and sense organs
Neuron - answera specialized cell transmitting nerve impulses; a nerve cell.
sensory function of nervous system - answerGathers internal & external environmental
information to CNS
Integrative function of the nervous system - answerMakes the decision as to what
needs to be done. "thinking" to CNS
motor function of nervous system - answerEffects a change to maintain homeostasis,
brain tells effectors, causes muscles or glands to take action in order to help maintain
homeostasis.
Astrocytes - answerProvide structural and metabolic support for neurons. Provide brain
barrier.
