Describe the general structure and function of the nervous system. The Nervous System is a "network" which delivers information and monitors the processes taking place in our bodies at all times. The nervous system in all its aspects allows us to function as a single controlled and coordinated unit. The basic nerve cell nerve cell is a neuron; a chain of neurons is actually a "communication cable "inside our bodies. Neuron structure is basically the cell nucleus‚ the dendrites which receive information

2012 The Comparison of Nervous Systems in Humans‚ Cnidarians‚ Flatworms‚ and Annelids The nervous system is one of the most important organ systems in the body. It is in charge of all of the things that happen within the body. Being responsible for receiving sensory input from internal and external stimuli‚ integrating and processing information‚ and generating output‚ it would be hard to survive without a nervous system; however‚ there are different types of nervous systems in various organisms

cord‚ our central nervous system and our nervous system. The spinal cord carries messages to the brain and also to the nerve cells that carry messages from the brain. Your body senses everything. Like something smashing your toe. You react to it. It all sends itself to the brain and it reacts. The cerebrum‚ controls thinking. The nerve cells carry information from all central nervous system. Like certain areas‚ such as the 5 senses. Sensory receptors get information from the body. The eyes‚

The nerve impulse The information is transmitted by polarity changes in the membranes of cells due to the presence of neurotransmitters that alter the ionic concentration inside the cell. Moreover‚ inside the neuron proteins and ions are negatively charged . This difference in ion concentration also produces a potential difference between the outer membrane and within the cell . The value reached is about -70 millivolts (negative inside with respect to the value of positive charges outside

Structure of main Body Systems: Our body is made up of many different systems which help us to keep alive. Without these systems our organs would not be able to functions at all. There are 10 main systems in our body which include the cardiovascular system‚ the digestive system‚ the renal system‚ the nervous system‚ the reproductive system‚ the immune system‚ the respiratory system‚ the lymphatic system‚ the muscular –skeletal system and lastly the endocrine system. Each of these systems has their own
