Autonomic Plexuses
Fig. 17.1 Autonomic plexuses in the abdomen and pelvis
Anterior view of the male abdomen. Removed: Peritoneum and majority of the stomach
Innervation of the Abdominal Organs
Fig. 17.2 Innervation of the anterior abdominal organs
Anterior view. Removed: Lesser omentum, ascending colon, and parts of the transverse colon. Opened: Lesser sac. The anterior and posterior vagal trunks each produce a celiac, hepatic, and pyloric branch, and a gastric plexus. See p. 245 for schematic.
Fig. 17.3 Innervation of the urinary organs
Anterior view of the male abdomen and pelvis. Removed: Abdominal organs and peritoneum. See p. 246 for schematic.
Innervation of the Intestines
Fig. 17.4 Innervation of the small intestine
Anterior view. Partially removed: Stomach, pancreas, and transverse colon (distal part). See p. 245 for schematic.
Fig. 17.5 Innervation of the large intestine
Anterior view. Removed: Jejunum and ileum. Reflected: Transverse and sigmoid colons. See p. 245 for schematic.
Innervation of the Pelvis

Right pelvis, left lateral view. Reflected: Uterus and rectum. See p. 247 for schematic.
Fig. 17.7 Innervation of the male pelvis
Right pelvis, left lateral view. See p. 247 for schematic.

Clinical
Referred pain from the internal organs
The convergence of somatic and visceral afferent fibers to a common level of the spinal cord confuses the relationship between the perceived and actual sites of pain, a phenomenon known as referred pain. Pain impulses from a particular organ are consistently projected to the same well-defined skin area.
