Which nerve groups primarily control the lower body and bowel/bladder functions?

Explanation:
Lower body and bowel/bladder control come from the lumbar and sacral nerve groups that form the lumbosacral plexus. These nerve roots extend to the legs and to the pelvic organs, providing motor and sensory input as well as autonomic signals needed for bladder and bowel function. The thoracic nerves mainly innervate the trunk, the cervical nerves handle the neck and upper limbs, and the coccygeal nerves play a minor role with limited impact on major lower-body or pelvic functions. Thus, lumbar and sacral regions are the ones primarily responsible for these functions.
