one or more dendrons, which carry nerve impulses towards the cell body, and an axon, a single fibre that carries nerve impulses away from the cell body.the cell body that contains the nucleus, organelles and most of the cytoplasm of the neurone.They are adapted to carry electrical impulses from one part of the body to another. Effectors include muscles and glands, and so responses can include muscle contractions or hormone release. Effectors bring about responses, which restore optimum levels, such as core body temperature and blood glucose levels.The coordination centre, such as the brain, spinal cord or a gland such as the pancreas, which receives and processes information from receptors around the body.Cells called receptors, which detect stimuli (changes in the environment).The conditions are controlled in two ways with chemical and nervous responses. The conditions inside our body must be carefully controlled if the body is to function effectively. ![]() The nervous system allows us to react to our surroundings and coordinate our behaviour. ![]() the peripheral nervous system - nerve cells that carry information to or from the CNS.the central nervous system (CNS) - the brain and spinal cord.
