30 Οκτ 2023 · The suprascapular nerve is a mixed nerve, meaning that it provides both sensory and motor supply for the suprascapular region. The main function of this nerve is to provide motor innervation for two muscles, which are the supraspinatus and infraspinatus muscles.
Once the suprascapular nerve’s roots leave the neck, they come together to form the nerve inside the brachial plexus, then move on to the shoulder. The suprascapular nerve has four main branches, two motor and two sensory. The motor branches innervate the: Supraspinatus muscle. Infraspinatus muscle.
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 · Structure. Type: The suprascapular nerve is mostly a motor nerve, providing innervation to two key muscles of the shoulder: the supraspinatus and infraspinatus. It also carries some sensory fibers from the shoulder joint.
3 Οκτ 2022 · The suprascapular artery and vein run along with the suprascapular nerve to provide the nerve its blood supply. The suprascapular artery can function either as a branch of the thyrocervical trunk or as a direct branch of the subclavian artery.
The suprascapular nerve (SSN) provides motor innervation to the infraspinatus and supraspinatus muscles and a sensory branch to the posterosuperior shoulder.
The suprascapular nerve emerges from the superior trunk of the brachial plexus in the neck. It runs laterally through the posterior triangle and then through the scapular notch to the posterior scapular region. Here it runs with the suprascapular artery and innervates the supraspinatus muscle.
