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.
Often, how a back injury is treated will depend on whether the nerves or spinal cord are involved. Luckily, many low back injuries will not involve the spinal cord, which ends in the upper part of the low back (at the L1-2 disk). The lowest part of the cord is called the conus medullaris. If this part of the cord is injured, patients will have trouble with bowel, bladder, and sexual function.
