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 …show more content…
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
