S4-S5 refers to which anatomical region?

Explanation:
S4-S5 refer to the sacral region. The prefix S denotes sacral spinal segments, which are the nerves located in the lower part of the spine that supply the pelvic organs, perineum, and parts of the lower body. This distinguishes them from the cervical (neck), thoracic (mid-back), and lumbar (lower back) regions, which would be indicated by cervical, thoracic, or lumbar segments. In short, S4-S5 are sacral spinal segments.
