Frontal Lobe - the most anterior portion of the cerebral cortex (in front of the central sulcus); it is involved in reasoning, planning, parts of speech, movement, emotions, and problem-solving

Dendrite - one of the extensions of the cell body that are reception surfaces of the neuron

Corpus Callosum - the large bundle of axons which connect the two cerebral hemispheres. It disseminates information from the cerebral cortex on one side of the brain to the same region on the other side

Cerebral Hemispheres - right and left halves of the forebrain

Cerebellum - structure located in the back of the brain (dorsal to the pons) involved in central regulation of movement, such as basic movement, balance, and posture; comes from the Latin word meaning "little brain"; is divided into two hemispheres and has a cortex

Central Sulcus - the major groove which divides the frontal lobe from the parietal lobe

Central Nervous System (CNS) - portion of the nervous system that includes the brain and the spinal cord

Cell body - region of the neuron defined by the presence of a nucleus; also called the soma

Brainstem - also known as the hindbrain; region of the brain that consists of the midbrain (tectum, tegmentum), pons, and medulla; responsible for functions such as breathing, heart rate, and blood pressure
