A vertebral column extends from your skull to your pelvis. It is made up vertebrae‚ which are serrated by masses of Fibrocartilage which are called intervertebral disks. The disks are connected by ligaments. An infant has 33 separate bones in the vertebrae column; however‚ the adult column has 26 bones‚ because four form into the coccyx. While the other five bones form the sacrum. ( Hole‚ 210 )The vertebral column not only supports the head and the trunk of the body‚ but it’s also flexible enough

However if the cell body remains intact‚ cut or compressed the axons of the peripheral nerves can regenerate. However post trauma axon regrowth never exactly matches what existed before the injury‚ and a lot of the recovery involves retraining the nervous system to respond appropriately so that stimulus and response are coordinated.

offer stimulation. At birth the brain is still getting ready for full function. For the first three years after birth the brain’s job is to make connections with neurons. These networks can be made when impulses are sent and received by neurons. The axon delivers messages and the dendrite collects them. These links form what is called a synapses. During the first three years of birth the number of neurons stay the same while the number of synapses grow. From birth to the age of three the brain creates

Think about what would happen to your vision if specific tracts were cut along the path from the retina to the occipital lobe. What visual deficits would you experience if you cut the tract at the right or left optic nerve‚ optic chasm‚ or lateral axons extending from the occipital lobe? The optic nerve carries information from the retina
