  2. Brachial plexus - Wikipedia

    en.wikipedia.org/wiki/Brachial_plexus

    The brachial plexus is a network of nerves (nerve plexus) formed by the anterior rami of the lower four cervical nerves and first thoracic nerve (C5, C6, C7, C8, and T1).This plexus extends from the spinal cord, through the cervicoaxillary canal in the neck, over the first rib, and into the armpit, it supplies afferent and efferent nerve fibers to the chest, shoulder, arm, forearm, and hand.

  3. Brachial plexus injury - Wikipedia

    en.wikipedia.org/wiki/Brachial_plexus_injury

    A brachial plexus injury (BPI), also known as brachial plexus lesion, is an injury to the brachial plexus, the network of nerves that conducts signals from the spinal cord to the shoulder, arm and hand. These nerves originate in the fifth, sixth, seventh and eighth cervical (C5–C8), and first thoracic (T1) spinal nerves, and innervate the ...

    en.wikipedia.org/wiki/Nerve_point_of_neck

    Injury to Erb's point is commonly sustained at birth or from a fall onto the shoulder.The nerve roots normally involved are C5 and partly C6. Symptoms include paralysis of the biceps, brachialis, and coracobrachialis (through the musculocutaneous nerve); the brachioradialis (through the radial nerve); and the deltoid (through the axillary nerve).

  5. Nerve plexus - Wikipedia

    en.wikipedia.org/wiki/Nerve_plexus

    The brachial plexus is formed by the ventral rami of C5-C8-T1 spinal nerves, and lower and upper halves of C4 and T2 spinal nerves. The plexus extends toward the armpit. The ventral rami of C5 and C6 form upper trunk, the ventral ramus of C7 forms the middle trunk, and the ventral rami of C8 and T1 join to form the lower trunk of the brachial ...

  7. Plexopathy - Wikipedia

    en.wikipedia.org/wiki/Plexopathy

    Brachial plexopathy is often caused from local trauma to the brachial plexus, as can happen from a dislocated shoulder.The disorder can also be secondary to compression or stretching of the brachial plexus (for example, during a baby's transit through the birth canal, in which case it may be referred to as Erb's Palsy or Klumpke's palsy).

  8. Upper trunk - Wikipedia

    en.wikipedia.org/wiki/Upper_trunk

    The upper (superior) trunk is part of the brachial plexus. It is formed by joining of the ventral rami of the fifth (C5) and sixth (C6) cervical nerves. The upper trunk divides into an anterior and posterior division. The branches of the upper trunk from proximal to distal are: subclavian nerve (C5-C6) suprascapular nerve (C5-C6)
