What makes us tick?\u00a0 Hopefully, there aren’t too many “nervous ticks” involved, but the nerves are central to who we are.\u00a0 They are signal pathways and, when combined into interwoven bundles, are control centres.<\/strong><\/p>\n

A few days ago <\/strong>a gentleman, who was giving our company an interesting talk on the harmful effects of drugs and alcohol on performance, asked for a few details of the nervous system.\u00a0 So, I thought a simplified summary of the whole nervous system (both Central and Peripheral) could be just the ticket… <\/strong><\/p>\n

The Nervous System<\/h2>\n

The Nervous System<\/a> is your body’s decision and communication centre. The Central Nervous System (CNS) is made up of the brain and the spinal cord whereas the Peripheral Nervous System (PNS) is made up of nerves (neurons). Together they control every part of your daily life, from breathing and blinking to helping you memorize facts for a test. Nerves reach from your brain to your face, ears, eyes, nose, and spinal cord… and from the spinal cord to the rest of your body. Sensory nerves gather information from the environment, send that info to the spinal cord, which then speed the message to the brain. The brain then makes sense of that message and fires off a response. Motor neurons deliver the instructions from the brain to the rest of your body. The spinal cord, made of a bundle of nerves running up and down the spine, is similar to a superhighway, speeding messages to and from the brain at every second.<\/p>\n

Central Nervous System<\/h2>\n

This consists of 2 structures: the brain and spinal cord. Different sections of the brain regulate and control various regions of our bodies.\u00a0 The main ones are:<\/p>\n
