English: An (admittedly extremely rough) schematic of the sacral plexus based on "Netter, Frank (2011) Atlas of Human Anatomy, Saunders Elsevier, pp. 487 ISBN: 978-1-4160-5951-6. " or equivalently the reproduction at this site.
In human anatomy, the sacral plexus is a nerve plexus which provides motor and sensory nerves for the posterior thigh, most of the lower leg and foot, and part of the pelvis. It is part of the lumbosacral plexus and emerges from the lumbar vertebrae and sacral vertebrae (L4-S4). [ 1 ]
The anterior divisions of the lumbar nerves, sacral nerves, and coccygeal nerve form the lumbosacral plexus, the first lumbar nerve being frequently joined by a branch from the twelfth thoracic. For descriptive purposes this plexus is usually divided into three parts: 3D Medical Animation still shot of Lumbosacral Plexus. lumbar plexus; sacral ...
The sacral sympathetic nerves arise from the sacral part of the sympathetic trunk, emerging anteriorly from the ganglia.They travel to their corresponding side's inferior hypogastric plexus, where the preganglionic nerve fibers synapse with the postganglionic sympathetic neurons, whose fibers ascend to the superior hypogastric plexus, the aortic plexus and the inferior mesenteric plexus, where ...
The obturator nerve is responsible for the sensory innervation of the skin of the medial aspect of the thigh.. The nerve is also responsible for the motor innervation of the adductor muscles of the lower limb (external obturator, [4] adductor longus, adductor brevis, adductor magnus, gracilis) and the pectineus (inconstant).
The anterior divisions of the lumbar nerves, sacral nerves, and coccygeal nerve form the lumbosacral plexus, the first lumbar nerve being frequently joined by a branch from the twelfth thoracic. For descriptive purposes this plexus is usually divided into three parts: lumbar plexus; sacral plexus; pudendal plexus

The sacral canal as a continuation of the vertebral canal runs throughout the greater part of the sacrum. The sacral angle is the angle formed by the true conjugate with the two pieces of sacrum. [clarification needed] Normally, it is greater than 60 degrees. A sacral angle of lesser degree suggests funneling of the pelvis. [clarification needed]
