Which language area provides understanding of the spoken and written word? Wernicke’s area
What structure is essential in storing memories and forming long-term memory? Hippocampus
Hypothalamus: function Regulates hunger and thirst;Regulates the autonomic nervous system ;Regulates circadian rhythms; Regulates body temperature
Thalamus: function Relay center for sensory input; Arousal from sleep
Releasing and inhibiting hormones, produced by the hypothalamus, are needed to control the Anterior pituitary gland
The area of the brain that processes visual, auditory, and touch stimuli and keeps us in a state of mental alertness is the Reticular activating system (RAS)
At 4 weeks old, the embryonic forebrain is called the Prosencephalon
The cerebral cortex is a region of the brain containing ____________ matter. Gray
Located within the diencephalon is the _____________ ventricle. Third
