Nervous System cells, tissues and organs of body are all working for organisms survival need to integrate all body activities for homeostasis need good communication and control: Nervous System Endocrine System receptor Neuroendocrine System integration effector Nervous System Structure every cell in our body responds to stimuli by changing its metabolism in one way or another but cells of the nervous system are highly specialized for receiving stimuli and conducting impulses to various parts of the body in humans, these nerve cells have become organized into the most complex and least understood of the body’s systems the main functions of the nervous system then are to 1. code information from external and internal environment (receptors, afferent) 2. process this information (CNS) 3. transmit an appropriate response (effectors) communicates by: electrochemical impulses (=nerve impulses) cell-to-cell chemicals (=neurotransmitters) CNS brain spinal cord PNS cranial nerves spinal nerves Anatomy & Physiology: The Nervous System; Ziser 2004 sensory neuron motor neurons 1
