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.
English: The branchial plexus, including all branches of the C5-T1 ventral primary rami. Includes mnemonics for learning the plexus' connections and branches. An original illustration by Chris Talbot, M.S. in Anatomy and student instructor at Case Western Reserve University.
Anatomical illustration of the brachial plexus. with areas of roots, trunks, divisions and cords marked. Clicking on names of branches will link to their Wikipedia entry.
The lateral pectoral nerve (also known as the lateral anterior thoracic nerve) arises from the lateral cord of the brachial plexus, [1] [2] and through it from the C5-7. [1] [2] It passes across the axillary artery and vein, [3] pierces the clavipectoral (coracoclavicular) fascia, and enters the deep surface of the pectoralis major to innervate ...
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 ...
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 ...
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)
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).
