Document Summary

Central nervous system: spinal cord and spinal nerves. Communication link between the brain and the pns highway ; provides a pathway for nerve impulses. Connects the brain to the peripheral nervous system via nerves. Bony structures are called vertebrae, they are stacked together to form the vertebral column. The smooth side is called the anterior side. Side with spiny processes is called the posterior side. Each spiny processes vertebrae has an opening called a vertebra foramen; a hole within the region where the spiny processes are. When we stack the vertebrae on top of each other, these holes create a canal; called the vertebral canal where the spinal cord itself is actually located. The vertebral canal is actually longer than the spinal cord; due to a difference in the speed of growth between these structures during development. Spinal cord stops growing in length at around 3-4 years old; vertebral column till early adulthood (maximum height/puberty reached)
