    Brachial plexus(臂神經叢)(C5~T1)

    由C5~T1 spinal nerves之 Anterior rami(前枝)所組成

    Plexus本身區分為 5段:Root(神經根)、Trunk(神經幹)、Division(神經分部)、Cord(神經索)、Terminal nerve(終末分枝)

    除了 division外,其餘各段皆會發出 spinal nerve

    Brachial plexus專門用於控制 upper limb skeletal mm.

    臂神經叢除支配上肢肌肉外,還同時支配肩帶肌肉(shoulder girdle mm.)

    故有部份 terminal n.直接由神經叢中發出支配肩部附近肌肉。

    有著名的 5 terminal nn.:

    Musculocutaneous n.(肌皮神經);Median n.(正中神經)、Ulnar n.(尺神經);Radial n.(橈神經)、Axillary n.(腋神經)
