Learn more about nerve system using these hands-on nerve diagrams that we have collected for you in high quality! In these 101 Diagramss, the detailed structures of the nervous system are illustrated in a high quality pictures. The nervous system has three main functions: sensory input, integration of data and motor output. Sensory input is when the body gathers information or data, by way of neurons, glia and synapses. Take a look at the first nerve diagram in the following image.
As you can see on the first nerve diagram above, the nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts. The structure diagram also shows that there are a of of nerves in our body. The brain and spinal cord form the control center known as the central nervous system (CNS), where information is evaluated and decisions made. The sensory nerves and sense organs of the peripheral nervous system (PNS) monitor conditions inside and outside of the body and send this information to the CNS. More detailed structure anatomy of the nerve system is shown through these diagrams.
The second diagram above shows that nerve is a bundle of axons in the peripheral nervous system (PNS) that act as information highways to carry signals between the brain and spinal cord and the rest of the body. Each axon is wrapped in a connective tissue sheath called the endoneurium. Individual axons of the nerve are bundled into groups of axons called fascicles, wrapped in a sheath of connective tissue called the perineurium.
