The human brain is one of the most complex organs in the entire human body. It controls the physical motion of a human being as well as all thought processes and functions that are both voluntary and involuntary throughout the human experience. The brain is the center of all activity and motion as well as the place where all feelings are developed on both a physical and emotional level. The human brain is filled with nerve endings that help it transfer sensations as well as the thought process associated with those sensations. When certain areas on the brain are accessed, information travels down the spinal cord and into the appropriately connected area of the human body.
The cells inside the human brain, which are all unique and intricate, are designed to be interconnected to transmit and receive information. Every time nerve endings in the brain receive information that information must be processed and then transformed into electromagnetic currents that caused the human body to react in either a thought process or physical movement. Sometimes the nerve endings transmit messages that require involuntary body functions such as breathing or blinking. Every area of the brain controls a different function.
This is the main reason why injury to the brain is so traumatic because, depending on the area injured, a patient can have a wide variety of side effects. The axon is the part of the cell that carries the information to the individual nerve endings to be sent throughout the body. If there is not the right amount of fat deposits in the brain, sometimes information gets lost. Furthermore, if nerve endings are damaged in the brain, there can be a loss of sense around the area that the information is supposed to be delivered to. There are different types of nerves to receive both internal and external stimulation
Sensory stimulation is very important, as are receptors, which tend to deal with the bodies of five physical senses. In the brain, there are very simple singular cell connections that are very reactive, and multilevel cell connections that require stimulation of millions of individual cells to get by the reactions. The more detailed a movement or thought process, the more individual cells need to be stimulated in order for the process to take place. Each of the four main parts of the human brain control different functions. If one part of the brain is damaged, the ability of an individual to perform certain types of activities will be impaired.
