The superior gluteal nerve originates in the sacral plexus. It originates from the lateral cord of the brachial plexus of nerves. These three nerves branch off the posterior cord of the brachial plexus. The nerves of the cervical plexus and brachial plexus can be affected. During embryogenesis in the choroid plexus of the ventricles, choroid plexus cysts can form. The pharynx is innervated by the pharyngeal plexus of the vagus nerve. Weakness of the shoulder girdle can lead to traction injury of the brachial plexus. These anastomoses of nerves form the sacral plexus and the lumbosacral plexus. It comes from the upper trunk of the brachial plexus. The hindgut is innervated via the inferior mesenteric plexus. The anterior distribution includes the cervical plexus (C1-C4) and brachial plexus (C5-T1). It is one of the five main nerves originating from the brachial plexus. Cerebral organoids are most similar to layers of neurons called the cortex and choroid plexus. A claw hand can result of injuries to the inferior brachial plexus (C8 - T1).
