The thoracodorsal nerve arises from the brachial plexus.It derives its fibers from the sixth, seventh, and eighth cervical nerves.It is derived from their ventral rami, in spite of the fact that the latissimus dorsi is found in the back.The thoracodorsal nerve is a branch of the posterior cord of the brachial plexus, and is made up of fibres from the posterior divisions of all . Is the suprascapular nerve a peripheral nerve? ; Middle trunk of the brachial plexus (C7); Lower trunk of the brachial plexus (C8 and T1); The trunks course through the scalene triangle (together with the subclavian artery) and the base of the posterior triangle of the neck . C3 ventral primary ramus. (1: posterior division of the upper trunk of the brachial plexus, 2: anterior division of the upper trunk of the brachial plexus, 3: lateral cord of the brachial plexus, 4: additional lateral root of the median nerve, SSM: subscapularis muscle, MN: median nerve, S: superior, I: inferior, L: lateral, M: medial). Which muscles does the suprascapular nerve innervate? Coming from the medial cords are two cutaneous branches that provide tactile sensation; these are called the medial cutaneous nerve of the arm and forearm respectively. The SSN travels deep to the trapezius (Trap) muscle and then enters the supraspinatus fossa. How do you know if you have long thoracic nerve damage? The suprascapular nerve is a peripheral nerve of the shoulder and arm.
