The document summarizes the neurovasculature of the pelvis, including: - The main arteries are the paired internal iliac arteries, paired ovarian/testicular arteries, unpaired median sacral artery, and paired superior rectal arteries. - The veins follow the corresponding arteries and empty into the inferior vena cava. - Nerves include the sacral and coccygeal plexuses which are somatic, and the pelvic part of the autonomic nervous system.

7. VEINS OF THE PELVIS AND PERINEUM
• Follows the corresponding arteries.
• They empties into the inferior vena cava.

PELVIS

9. NERVES OF THE PELVIS
• Somatic: Sacral and coccygeal plexuses
• Autonomic: Pelvic part of the autonomic nervous system

10. SACRAL PLEXUS
• Lumbosacral trunk

11. COCCYGEAL PLEXUS
• Small network of
nerve fibres formed
by the anterior rami
of S4 and S5 and
the coccygeal
nerves.

12. PELVIC AUTONOMIC NERVES
• Sacral sympathetic
trunks.
• Peri-arterial
plexuses.
• Hypogastric
plexuses.
• Pelvic splanchnic
nerves.
