• Suprascapular nerve- (C5,C6) branches off the upper trunk, courses across the posterior triangle of neck, through the suprascapular foramen, inferior to the transverse scapular ligament, (suprascapular a. and v. pass su-perior to the transverse scapular ligament) to supply the supraspinatus m.; continues through the greater scapu-
30 Οκτ 2023 · The suprascapular nerve is the lateral branch of the superior trunk of the brachial plexus. It receives nerve fibers that originate in the nerve roots C5 and C6 (and sometimes C4). The suprascapular nerve is a mixed nerve, meaning that it provides both sensory and motor supply for the suprascapular region.
19 Σεπ 2023 · The suprascapular nerve is a mixed motor and sensory nerve arising from the superior trunk of the brachial plexus. It supplies sensory innervation to the glenohumeral and acromioclavicular joints and motor innervation to the supraspinatus and infraspinatus muscles.
23 Σεπ 2023 · Location. Origin: The nerve originates from the brachial plexus in the lower part of the neck. Course: After originating, the suprascapular nerve runs laterally, crossing over the posterior triangle of the neck toward the superior aspect of the scapula.
Structure and Location . After branching from the upper portion of the brachial plexus, the suprascapular nerve travels down and at an outward angle toward the shoulder, passing behind the clavicle (collarbone).
Background The suprascapular nerve is largely responsible for the majority of the sensory innervation of the acromioclavicular joint. In this anatomical study, we describe, in detail, the anatomy of the sensory innervation of the acromioclavicular joint by the branches of the suprascapular nerve.
After its origin in the C4 to C5 cervical spine roots, the suprascapular nerve (SSN) arises from the upper trunk of the brachial plexus. It runs posterior to the clavicle and arrives at the suprascapular notch by passing beneath the transverse scapular ligament.
