A nerve plexus is a plexus (branching network) of intersecting nerves. There are spinal nerve plexuses; as well as other forms of autonomic plexuses, many of which are a part of the enteric nervous system. For the spinal plexuses, except for the ventral rami of Th2-Th12 nerves, they combine sets of ventral rami of spinal nerves that serve the same area of the body into one large grouped nerve. There are several in the body, including: *Cervical plexus - serves the head, neck and shoulders *Brachial plexus - serves the chest, shoulders, arms and hands *Lumbar plexus - serves the back, abdomen, groin, thighs, knees, and calves *Sacral plexus - serves the pelvis, buttocks, genitals, thighs, calves, and feet *Celiac plexus (solar plexus) - serves internal organs *Coccygeal plexus - serves a small region over the coccyx *Auerbach's plexus - serves the gastrointestinal tract *Meissner's plexus (submucosal plexus) - serves the gastrointestinal tract ==Spinal plexuses== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「nerve plexus」の詳細全文を読む スポンサード リンク
