Major Brain Function
The Brain has five major structures . These structures include the mesencephalon, metencephalon, myelencephalon (or medulla), telencephalon, and diecephalon. All of these brain structures contribute different functions within the human body.
The brain’s first structure is the myelencephalon, which is also called the medulla. The myelencephalon is known as the most posterior part of the brain. The structure of the myelencephalon is made up of bundles of axons called tracts. These tracts carry signals between the rest of the body and the brain. The myelencephalon also contains a reticular formation, which consists of a complex system of 100 tiny nuclei occupy the central core of the brain stem from the bottom extremity of the myelencephalon …show more content…
The telencephalon contains the cerebral cortex. The telencephalon also consists of many other structures such as the major fissures which are big grooves in a complex cortex it includes the longitudinal fissure, lateral fissure, and central fissure. It also consists of the most important gyri’s that are located in the frontal, parietal, and temporal lobes, respectively (Pinel, 2011). The gyri include the precentral gyri, the postcentral gyri, and the superior gyri which are the largest (Pinel, 2011). The cerebral commissures are also located in the telencephalon, which are hemisphere connecting tracts (Pinel, 2011); the biggest tract is the corpus callosum. The limbic system is also located in the telencephalon. The limbic system regulates behaviors that are motived and consist of major structures that surround the thalamus such as; the amygdala, the fornix, the cingulate cortex, and the septum. The basal ganglia is the last structure in the telencephalon. The basal ganglia’s function is to regulate voluntary motor responses. The basal ganglia includes structures such as the amygdala, the caudate, the putamen, and the globus pallidus. The telencephalon begins voluntary movement, interprets sensory input, and mediates complex cognitive processes such as learning speaking and problem solving (Pinel,
