The cerebrospinal fluid (CSF) lies between the inner and middle layers, which, provides cushioning and ions to the brain and spinal cord. It does so by restricting their behavior or activities so that the overall control objectives of the distributed system are met. Each hemisphere is divided into four major lobes. The outer most layer is tough and fibrous and provide mechanical support. In organisms, various organs and systems participate and play their role as and when required. Coordination Meaning Coordination is the function of management which ensures that different departments and groups work in sync. This (electrical) impulse, which travels from the dendrite tip to the cell body, and then along the axon to its end of the axon, sets off the release of some chemicals. Reflex action is an automatic nervous reaction that cannot be consciously controlled and reflex arc is the nervous pathway which carries the impulses causing a reflex action. The messages of the type of response are passed via motor neurons or nerves to the particular effectors which produce a specific response. Start studying Biology: Coordination. If temperature is too high, the enzymes could become denatured. Likewise, the nervous tissue is made up of an organized network of nerve cells or neurons, and is dedicated for carrying information via electrical impulses from one part of the body to another. Resting above the hypothalamus is the thalamus which provides connections between many parts of brain and between sensory system and cerebrum.
