![]() It is encircled by a layer of connective tissue called the perineurium. The epineurium, also known as the connective tissue sheath, is the protective covering of the nerves, it is important to not be confused with the myelin sheath, which is the outer covering of neurons.Ī bundle of nerve fibres is known as fasciculus. The motor neurons are an example of such nerves.Ī mixed nerve contains both the sensory and motor neurons. The motor nerves constitute the efferent fibres that have characteristics of long axons. The sensory nerve contains the afferent fibres which have the characteristic feature of the long dendrites. The nerve is made up of nerve fibre, which contains neurons. Let us see the structural details of the nerves. The nervous system function can be better understood by understanding the structure and functions of nerves in the human body. We have developed a basic understanding of the nervous system and have seen a simple nervous system diagram. The nervous system facts function and diseases are briefly discussed in the article. The article also describes the classification of the human nervous system along with a discussion of the central nervous system diagram. The article defines the human nervous system along with the nervous system diagram, the article specifically discusses the nervous system function and the nerves in the human body. ![]() Some of the most common stimuli include the following sound, light, air, heat, smell, taste, and gravity. The response of the nervous system is defined as the conduction of the stimulus in the form of an electrochemical message. The message that an organism gains from the external environment are defined as a stimulus. Organisms adjust their movements and orientations in reaction to changes in the external environment. The nervous system consists of a network of neurons and synapses that transmit information from the brain and spinal cord to other portions of the body. The nervous system is defined as a systematic collection of cells designed for the transmission of electrochemical inputs from sensory neurons to the region where a reaction occurs through a network.
