Neurapraxia is a reduction or complete block of conduction across a segment of a nerve with axonal continuity conserved. (medscape.com)
[ 12 ] Peripheral nerves are stimulated by somatosensory evoked potentials (SSEPs), and if signal conduction is disrupted along any segment of the circuit, an evoked potentiation is not produced. (medscape.com)
NCS/EMG (nerve conduction study/electromyography). (clevelandclinic.org)
The assessment of nerve injury includes a careful neurological examination, sometimes accompanied by tests, e.g., electromyography or nerve conduction studies. (unboundmedicine.com)

Ultrasound guidance, compared with anatomical landmark and paresthesia techniques, can provide direct visualization of the target nerve, surrounding tissue, and injectate spread, and may lead to improvement in patient safety for decreased nerve injury or other serious complications including local anesthetic systemic toxicity and pneumothorax [ 5 , 7 , 8 - 11 ]. (anesth-pain-med.org)
Technical skills, such as needle manipulation during ISB using a nerve stimulator, as well as anatomical landmarks and the types of local anesthetic drug used for ISB, are important neurological risk factors [ 1 ]. (anesth-pain-med.org)

The upper trunk provides part of the nerve to supply to the upper extremity via the Musculocutaneous, Axillary, Radial and Median nerves. (wikipedia.org)
The anterior divisions of the upper and middle trunks unite to form the lateral cord, which is the origin of the lateral pectoral nerve (C5, C6, C7). (medscape.com)
