The recommended dietary allowance for iodine is 200 mcg/day during pregnancy and 75 mcg/day while breastfeeding. For the rest of us, the answer for optimum thyroid health is, therefore, to get enough -- but not too much -- iodine. You might be deficient in iodine if you have, for health reasons, cut iodized salt out of your diet, or switched to non-iodized sea salt.
The brain and spinal cordâ¦ together make up the central nervous system. The spinal cord begins at the occipital bone and extends down to the space between the first and second lumbar vertebrae; it does not extend the entire length of the vertebral column. It is around 45 cm (18 in) in men and around 43 cm (17 in) long in women.
The spine is also designed to protect your spinal cord. The spinal cord is a column of nerves that connects your brain with the rest of your body, allowing you to control your movements. Without a spinal cord, you could not move any part of your body, and your organs could not function.This is why keeping your spine healthy is vital if you want to live an active life.his is why damage to the spinal cord can cause paralysis in certain areas and not others -- it depends on which spinal nerves are affected. The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen.
