- Left lower quadrant (LLQ): small intesine, left ureter, sigmoid flexure, descending colon, bladder if distended, left spermatic duct in the male; left ovary and left tube, and uterus if enlarged, in the female.
- Richt upper quadrant (RUQ): right lobe of the liver, gallbladder, part of transverse colon, part of pylorus, hepatic flexure, right kidney, and duodenum.
- Right lower quadrant (RLQ): cecum, ascending colon, small intestine, appendix, bladder if distended, right ureter, right spermatic duct in the male; right ovary and right tube, and uterus if enlarged, in the female.
Lacking these reflexes indicates damage to the pyramidal tract or the projection neurones in the cerebral cortex and the hippocampus of the brain or two groups of nerve fibers that participate in the complex and delicate coordination of motor activity arising in the brain and passing down through the spinal cord to motor cells.
An indication for the need of surgical intervention include fetal distress (fetal hypoxia or low oxygen levels in the fetus) associated with dystocia (difficult or painful childbirth labor or delivery), arrested descent (interruption in the labor process), abruptio placentae (placenta prematurely separating from the wall of the uterus), or umbilical cord prolapse (slipping or falling out of place).
