INTRODUCTIONThis report is based on the biological communication system. It explains role of nervoussystem in the human body. Apart from this, it also describes the role of chemical transmitter inenabling impulse to cross synapses. Moreover, it also focuses on the effect of caffeine in thehuman body.1.1 Structure of the central nervous system, sensory, connector and motor neurones.Human ability to see, hear and smell depends upon the nervous system. Our ability of acton the information also depends on the nervous system. This system depends on theinterconnected cells (Ghosh and Pye, eds., 2014). Whereas cell is functional unit of life becausethey provide structure for body, it takes nutrients from food and convert those nutrients intoenergy. There are different types of nerve cells in human body for e.g. motor neurones, axons,synapses etc. Mainly, nervous system is made up of specialized cells such as glial cells and nervecell. In human and other vertebrates, the nervous system is divided into two parts such as CentralNervous System (CNS) and Peripheral Nervous System (PNS).CNS: This nervous system is consisted by brain and spinal cord. Through this nervoussystem, person is able to gain information.PNS: It is consisted by part of neurons which are find outside of the central nervoussystem such as motor nerve cell and sensory nerve cell. Sensory never cell brings signalinto the human body and motor neurons carry out signals. Motor neurons are located inthe central nervous system. Sensory nervous system provides information about touch,position, pain, temperature etc. through this system human can act.Motor neurons: Motor neurons get information from other neurons and then convert andtransfer those information and signals into muscles, organs and glands. For example: Ifperson picked up a hot glass water, motor neurons supply the muscles in the person'sfinger would cause his hand to let go (Hotchkin and Parks, 2013).Sensory neurons: The main role of these neurons in the human body is to get informationor signal about inside and outside of the body and transfer this information into thecentral nervous system so it can be processed.1
