Join us for this lecture where Professor Zach Murphy explores the anatomy and organization of the sacral plexus, a major nerve network that provides motor and sensory innervation to the pelvis, posterior thigh, most of the lower leg, and foot. We begin with its formation from the lumbosacral trunk (L4-L5) and the anterior rami of S1 through S4, explaining how these nerve roots unite within the pelvis on the anterior surface of the piriformis muscle. We then examine the major branches of the sacral plexus, including the superior gluteal, inferior gluteal, sciatic, posterior femoral cutaneous, pudendal, and smaller motor branches to deep pelvic and gluteal muscles. Each nerve is described in terms of its anatomical course, muscular innervation, and sensory territories. Special emphasis is placed on the sciatic nerve as the largest branch, highlighting its bifurcation into the tibial and common fibular nerves, and their functional significance in lower limb movement and sensation. Finally, we connect the sacral plexus to its clinical importance by discussing its relationships to surrounding pelvic structures, vessels, and muscles, ensuring a strong three-dimensional understanding. This integration helps clarify how the sacral plexus coordinates with the lumbar plexus to provide comprehensive innervation of the lower extremity.
