Lumbosacral Plexus Formation The lumbosacral plexus is formed by the lumbosacral trunk and the ventral rami of the first to third sacral nerves and part of the fourth sacral nerve. The special senses are served through the cranial nerves as well as the general senses of the head and neck.
Besides the eyes the orbits host several structures that support the eyeballs including muscles vessels nerves and a gland. The solar plexus received its name due to its resemblance to the suns rays with the nerves meeting at the center.
