In surgical procedures involving dissection of the brachioradialis muscle more proximal than 50 mm distal to the elbow, the extramuscular branch (es) of the radial nerve branches to the brachioradialis may be at risk. Nerve Supply : It is supplied by radial nerve. The interscalene block can also be utilized for surgery of the arm or forearm; however, the higher incidence of incomplete blockade of the inferior trunk with this technique may provide inadequate analgesia in the ulnar distribution. - function: - brachioradialis muscle assists in elbow flexion and is also a semipronator and … Brachioradialis: The brachioradialis is a paradoxical muscle. • Branches of the radial nerve provide elbow extension, occasional elbow flexion (variably through the brachioradialis muscle as well as a branch to the brachialis muscle), supination of the forearm (although the biceps muscle innervated by musculocutaneous nerve is the major supinator) and wrist/finger/thumb extension. The radial nerve (C5-T1) is a continuation of the posterior cord and provides motor innervation to all muscles in the posterior arm and forearm. BRACHIORADIALIS: The brachioradialis is a muscle of the forearm that flexes the forearm at the elbow. The symptoms are pain and paraesthesia over the radial aspect of … The posterior interosseous nerve supplies all the muscles of the posterior compartment of the forearm, except anconeus muscle, brachioradialis muscle, and extensor carpi radialis longus muscle. The brachioradialis muscle is most visible when the forearm is half pronated, and flexing at the elbow against resistance. From the upper trunk C5 and C6 give rise to the nerve to the subclavius, and the suprascapular nerve, that supply the subclavius muscle, and the supra- and infraspinatus muscles, respectively. The brachioradialis muscle is innervated by the radial nerve (C5, C6, C7). The sensory branches of the radial nerve supply sensation to the dorsum of the arm, forearm, and hand. The interscalene block is indicated for procedures on the shoulder and proximal humerus as well as the lateral two thirds of the clavicle. Citing Literature The Brachioradialis is a superficial posterior muscle of the forearm. The radial nerve is one of the terminal branches of the posterior cord. The brachioradialis muscle covers the bifurcation of the radial nerve as it divides into the superficial and deep branches. superficial radial n. is located deep to the brachioradialis muscle: subclavius m., n. to: superior trunk of the brachial plexus: no named branches: subclavius m. no cutaneous branches: nerve to subclavius m. is one of two nerves to arise from the superior trunk of the brachial plexus; suprascapular n. is the other one: subscapular, lower Of the muscles that receive innervation from the radial nerve, it is one of only four that receive input directly from the radial nerve. Nerve supply. Radial nerve supply the BEST muscles. Action : It act as elbow flexor and also as supinator and pronator of radioulnar joint at 90`. The nerve supply to the upper limb is almost entirely supplied by the brachial plexus , a complex intercommunicating network of nerves formed in the neck by spinal nerve roots C5, C6, C7, C8 and T1. This muscle connects the humerus to the radius at the styloid process. The brachioradialis primarily flexes the forearm at the elbow but also functions to supinate or … The main blood supply of the brachioradialis muscle is the recurrent radial branch of the radial artery. Of the muscles that receive innervation from the radial nerve, it is one of only four that receive input directly from the radial nerve. The brachioradialis is innervated by the radial nerve (C5, C6) - a branch of the brachial plexus. Figure 1 summarises the structure and branches of the brachial plexus. The extramuscular branches of the radial nerve to the brachioradialis were dissected and studied in 43 embalmed cadaveric specimens. The brachialis is most active when the shoulder is in flexion, as well as during isometric elbow flexion, regardless of forearm position. Origin: lateral supracondylar ridge of humerus There are three major sensory branches: (1) the posterior brachial ... brachioradialis reflexes; and loss of sensation along the dorsum of the arm. Blood supply. The brachioradialis muscle receives arterial blood supply from the radial recurrent branch of the radial artery and radial collateral artery of the deep brachial artery. The radial nerve innervates the muscles located in the posterior arm and posterior forearm. Nerve innervation to the brachialis muscle is the musculocutaneous nerve and some parts of the radial nerve. It plays important role in wrist pathology such as ulnar impaction syndromes and thinning of the triangular fibrocartilage complex.. Radiographic features. Clin. 488 - 492 CrossRef View Record in Scopus Google Scholar Despite the bulk of the muscle body being visible from the anterior aspect of the forearm, the brachioradialis is a posterior compartment muscle and consequently is innervated by the radial nerve. This muscle originates at the lateral supracondylar ridge of the humerus and inserts at the styloid process of the radius.

We studied the innervation and organization of motor units in the brachioradialis muscle of 25 normal human subjects. The nerve supply to the human brachialis muscle has been investigated by many researchers with gross anatomical and/or microdissectional methods. Extensor carpi radialis longus receives innervation from the radial nerve, with contributions mainly from spinal nerves C5-C8 Low radial nerve palsy occurs when the radial nerve is injured at the level of elbow, so that the muscles supplied by the radial nerve in the distal arm (Brachioradialis and Extensor Carpi radialis longus) are spared. Nerve Due to its location in the posterior compartment of the forearm the brachioradialis is innervated by the radial nerve. The muscular branches of the radial nerve supply the Triceps brachii, Anconæus, Brachioradialis, Extensor carpi radialis longus, and Brachialis, and are grouped as medial, posterior, and lateral..
