Role of the Brain, Nervous System, & Sensory Systems
In humans, the nervous system is the area in which the body processes and sends messages. It is a complicated system that gathers sensory information from the entire body, replies to changes in the body, evaluates request information, begins and implements all bodily activity, and preserves “homeostasis” in the body. An organism nervous system is separated into two systems: the “central nervous system (CNS) and the peripheral nervous system (PNS).” The brain and the spinal cord is a part of the CNS. The PNS is made of into the “somatic nervous system and the autonomic nervous system,” these two areas are separated into the “sympathetic nervous system and the parasympathetic nervous system.”

These nerve fibers extend from the brain; to a person’s facial features, hearing, vision, and smelling, and behavior. As a result, the spinal cord gets communications from the brain and sends out signals to a person’s body. The sensory nerve fibers in the body collect data in a person’s environment, sends out that communication to the spinal cord and this quickly transmission signals to the brain. The brain assesses and evaluates the memo and respond to the behavior. “Motor neurons” carries out instructions via the brain to the entire body. A human spinal cord consists of bundles of nerves going vertical and horizontal down the spine area, is similar to an arterial highway, sending communications to the brain at every millisecond to shape human behavior (Bear et al., …show more content…
Neuronal activity has specific structures that allow them to transmit communications quickly and correctly to other cellular structures. They convey these communicate by way of “electrochemical waves traveling along thin fibers called axons.” This causes the release of neurotransmitters between the synapses. Cells that get an impulse at the synapse will cause the neurons to be “excited, inhibited, or otherwise modulated.” The associations involving the neurons can create “neural circuits and neural networks” that construct a person’s outlook on their environment which influence their behavior. The “motor function of neurons” of these structures of the brain is important for the appropriate function of “mental cognition.” This brain produces a compound that has a biological function for human behavior. This is associated with sustaining a healthy mental condition by permitting the regular “cognitive mental processes.” Research shows that individuals who have an extreme amount of dopamine in their body can acquire “cognitive dysfunction” that is displayed by psychotic ideas that are disconnected from reality. Additional research surveyed the manifestations of this “biochemical disorder” are the growth of “paranoic symptoms” as part of the handicapped cognitive function in these affected individuals (Kalat,
