Plexus sacralis

This tutorial by Ken Hub, led by Coco, delves into the complex anatomy of the sacral plexus, a network of nerves formed from the anterior rami of spinal nerves L4 to S4. The video covers the sacral plexus's location, composition, and the spinal nerves involved. It also explores the larger nerves that innovate the lower extremities, the gluteal region, and the perineum. The tutorial provides learning tips and clinical context, such as sciatica pain, to help understand the sacral plexus's practical implications.
