The brain is the central control center of the other organ systems of the body.
Although most of all the other parts of the body show how they work; the brain, which
does more than any other organ, shows the least of evidences of function (Kluger, 2007).
This three pound piece of wrinkled tissue not only serves as the central control center but
is, also the place of one’s mind, thoughts, and sense of all existence.
In the brain are five
major structures of the brain and each structure functions in the human body. The five
structures are telencephalon, diencephalon, mesencephalon, metencephalon, and
The telencephalon structure is a vast area of the brain.
The telencephalon is the
frontal part of the brain toward the oral and nasal regional area to the midbrain. The
outmost portion of the telencephalon is the cerebrum or called the cerebral hemisphere.
The outer lays of the cerebral hemispheres consists of a wrinkled outer lays of gray matter
called cerebral cortex (Nervous system, 2009).
The telencephalon has many functions. The telencephalon determines intelligence
(e.g. speech and abstract thoughts (Nervous system, 2009),
determines personality, permits
for the interpretation of sensory impulses, and manages the control of voluntary
movements (Nervous system, 2009). Additionally, the telencephalon, plans and organizes,
manages the sense of smell, and the touch of sensation.
Within the hemispheres of the cerebrum within the telencephalon there is a
dominant hemisphere and a non-dominant hemisphere. The dominant hemisphere controls
language, mathematical and analytical functions, and handedness (Nervous system, 2009).
