The enteric brain is the mind of the gut, which functions to send and receive impulses, respond to emotions, and record experiences. It contains neurotransmitters that influence the nerve cells. This brain is situated in the sheaths of the tissues that line the esophagus, colon, small intestines, and stomach. Moreover, the enteric brain contains a network of neurons as well as proteins that transmit messages across the support cells, neurons, and the complex circuitry that makes it possible for the enteric brain to act independently, remember, and learn. This brain plays an integral role in psychology, with regard to misery and happiness. The enteric system is made up of neurotransmitters, such as nitric oxide, norephinephrine, glutamate, dopamine, …show more content…

The cerebrum has a surface called the cerebral cortex, which is made up of sic thin layers of neurons sitting on top of the white matter pathways. This part contains over 10 billion neurons. The cortex contains convolutions with ridges called gyri and valleys known as sulci. The sulci serve as the boundaries of the four lobes of the cortex, the frontal lobe, motor cortex, parietal lobe, and the temporal lobe.
The frontal lobe functions to initiate voluntary movements and planning and as such, is the most important lobe for intelligence and personality. The motor cortex, on the other hand, is located at the back portion of the frontal lobe, along the sulcus separating the parietal lobe. This part of the cerebrum is responsible for initiating the movements of different body muscles and limbs. For instance, the motor cortex’s lowest portions, adjacent to the temple work to control the face and mouth muscles. Moreover, the part near the top of the head is responsible for feet and leg …show more content…

It contains a special area called the auditory cortex and is intimately connected to the ears, thereby making it a hearing aid. It is situated near the connection of the parietal lobe, frontal lobe, and the temporal lobe. The cerebrum is also made up of the occipital lobe, which is located at the back of the head. Located at the back of the occipital lobe is the visual cortex, which is responsible for receiving information from the eyes. This part thus plays an important role in vision functions. Other areas that are not specialized include the associative cortex, which work to connect the motor and sensory cortices. These parts are also believed to store memories and produce thought
