the hair matrix that continually undergoes cell division, producing the keratinocytes of
the epidermis
basal ganglia - CORRECT ANSWER: structures in the forebrain that help to control
movement

responsible for automatic survival functions
, Broca's area - CORRECT ANSWER: Controls language expression - an area of the
frontal lobe, usually in the left hemisphere, that directs the muscle movements involved
in speech.
