Flexion is the most extensive of all the movements of the vertebral column, and is freest in the lumbar region. In extension, or movement backward, an exactly opposite disposition of the parts takes place. This movement is limited by the anterior longitudinal ligament, and by the approximation of the spinous processes.
Iodine Allergy in Dogs. As crabs contain small amounts of iodine, and some dogs are allergic to iodine, observer your dog carefully when first giving her crab meat. If your dog shows symptoms such as watery eyes and nose, stomach upset or lethargy, your dog might be allergic to iodine, and itâs not a good idea to continue giving your dog crab meat.
Large land crabs crawl into our yard frequently. Our dogs kill the crabs, but do not eat the meat. They eagerly eat other game that they kill on the property: iguana, birds who fly to low, occasionally a ferrel chicken. But not crab. Maybe they know something that I do not.
