lateral cord การใช้
- The "'lateral nerve "'( "'lateral anterior thoracic nerve "') arises from the lateral cord of the brachial plexus, and through it from the fifth, sixth, and seventh cervical nerves.
- It contributes to the phrenic nerve, long thoracic nerve, and dorsal scapular nerve before joining cervical spinal nerve 6 to form the upper trunk, a trunk of the brachial plexus, which then forms the lateral cord, and finally the musculocutaneous nerve.
- It arises either from the lateral cord or directly from the anterior divisions of the upper and middle trunks of the brachial plexus, unlike the medial pectoral nerve, which derives from the medial cord ( or directly from the anterior division of the lower trunk ).
- Additionally there are : ( C5-C8, and T1 ) Brachial plexus, providing the entire nerve supply of the shoulder and upper limb; and includes supraclavicular branches ( dorsal scapular, suprascapular, long thoracic ) lateral cord ( musculocutaneous, lateral antibrachial cutaneous, lateral head of median nerve ), medial cord ( ulnar, medial head of median nerve, medial antibrachial cutaneous, medial brachial cutaneous ), posterior cord ( axillary, radial ), controlling the arm.
