| The nerve to the short head of the biceps femoris sometimes arises directly from the sacral plexus. |
| Intraventricular meningiomas are rare but typically occur around the choroid plexus in the trigone of the lateral ventricles. |
| These neuroendocrine tumors arise from the adventitia of the jugular bulb or the neural plexus within the middle ear space. |
| In addition, recent biopsy studies indicate that diabetic amyotrophy is due to microvasculitis in the lumbosacral plexus. |
| There is contiguous spread to the ipsilateral ACA and MCA via a perivascular plexus supplied by the ophthalmic division of the trigeminal nerve. |
| In contrast to the innervation of the proximal esophagus, axons from vagal neurons synapse within ganglia of the myenteric plexus. |
