The __________ is the innermost region of the brain.
Aiding in emotional processing and arousal functions are functions of the
The organ that acts as the control center for the body
Brain; Brain processes allow us to coordinate movement, process information, and interact with the world around us
The anterior region of the brain that is comprised of the cerebrum, thalamus, and hypothalamus
forebrain; The forebrain is the largest and most complex region of the brain.
The region of the brainstem that is located between the forebrain and hindbrain
midbrain; Before our brain can fully integrate our audio and visual sensory information, it must first be projected through the midbrain.
The region of the brain that is located underneath the forebrain and the midbrain.
hindbrain; The hindbrain contains all of the structures positioned lowest in the brain
The largest part of the forebrain that is responsible for the integration of sensory and neural functions
cerebrum; The cerebrum is divided into two hemispheres and houses the cerebral cortex
The brain structure that serves as the main input center for most sensory information.
thalamus; All incoming sensory information is sorted through the thalamus and sent to the higher brain centers for further processing
The innermost region of the brain that includes structures of the midbrain and hindbrain.
brainstem; The brainstem plays a very important role in the conduction of neural impulses up to the brain, as it is where the reticular formation is found.
Brain structure located in the hindbrain that is largely responsible for unconscious biological functions
medulla; Biological functions regulated by the medulla include breathing, heart and blood vessel activity, swallowing, vomiting, and sneezing.
Structure located in the hindbrain that connects the brainstem to the cerebellum.
pons; The pons is adequately named from the Latin term for “bridge” because it connects the brainstem to the cerebellum.
Brain structure located at the back portion of the brainstem
cerebellum; Hand-eye coordination is one example of the function of the cerebellum
