Central Nervous System Essay

Decent Essays
The nervous system in the body is divided into Central Nervous System (CNS) and Peripheral Nervous System (PNS). Central nervous system controls all important nerves inside the body enable the body to do its daily tasks. Peripheral nervous system is the system that control on the outside the brain and spinal cord. Both systems are requiring in the body for different functions.
The central nervous system consists of the nerves in brain and spinal cord. The brain is responsible for organize and coordinate the information. Consciously and unconsciously, the brain has many functions such as to think, feel and homeostasis regulation in the body. It receives sensory inputs from the spinal cord and transfer out as the motor outputs. The spinal cord

Forebrain made up of a pair of large cerebral hemispheres also known as the telecephalon and a set of structures sit deep in the cerebellum called diencephalon. Diencephalon includes the thalamus, lateral geniculate nucleus (LGN), hypothalamus, and posterior lobe of the pituitary. Thalamus allows all the sensory inputs (except for olfactory nerve) to go through to the somatic sensory regions of the cerebral cortex. LGN allows the signals to go from the optic nerve to process and going to multiple visual places in the cerebral cortex. Hypothalamus maintains the homeostasis regulation for temperature and blood chemistry. It also releases oxytocin and vasopressin to the posterior lobe of the pituitary to send out into the blood. The hindbrain consists of medulla oblongata, pons, and cerebellum. Medulla oblongata regulates and adjusts the blood flow as well as the heart beats. The pons carries the messages from the different areas of the cerebral cortex to the cerebellum, and then the cerebellum will coordinate and carry out the movements of the body. The midbrain, also known as the mesencephalon, correlates with vision, hearing, motor control, alertness, and temperature regulation in the

    The main three sections of the brain are the hindbrain, the limbic system, and the cerebral cortex. The hindbrain consists of the medulla which is directly above the spinal cord and controls breathing, heartbeat, and other vital life functions like the things we don’t have conscious control over. It also has pons which are in the uppermost level of the hindbrain and just above the medulla, they serve as a bridge and information from higher parts of the brain revels through these to get to the cerebellum which is behind the pons, at the back of the brain stem also known as “little brain” this coordinates movement, balance, and posture. The last thing the hindbrain has in the reticular formation which is located at the core of the medulla and pons. They are groups of specialized neuron that project up to higher brain regions and down the spinal cord and regulate alert and attention.…

    Topic: Understanding the Key Aspects of the Brain and the Nervous System. The entire human body activity relies on the brain function, in this first section of this report I will try to discuss the major structures, the functions as well as the major methods of studying the brain. The brain is in charge of all body functions, such as the ability to make decisions, do activities, learning and all everyday life stuff. The brain is situated in the skull protected by brain blood fluid. In the second section I will discuss the differences between Glial Cells and Neurones in relation to their structure and function, including the communication process amongst the Neurones and various types of Neurotransmitters as well as the conducts with which…

    The central nervous system is crucial to human function; it consists of the brain, spinal cord and a network of nerves moving to the rest of our body. It controls everything in the body e.g. emotions, senses, responses, reactions, body balance like temperature and heartbeat as well as movement of our muscles and glands. The CNS (Central nervous system) covers the brain and spinal cord where the PNS (Peripheral nervous system) is made up of the nerve fibre’s that branch off from the spinal cord and extend to all parts of the body, including the neck and arms, torso, legs, skeletal muscles and internal organs. The brain is the control centre of the nervous system, it co-ordinates the body function.…

    The central nervous system is the source of transportation to send signals from cells to other cells, to other parts of the body, or to receive feedback. This is carried out by nerve fibers that carry out electrical impulses. Nerves that run from the brain towards the dorsal parts of the brain and neck are part of the peripheral nervous system. These nerves run throughout the entire body. The nerves that are entering and exiting the spinal cord are also part of the peripheral nervous system.…
