Overview of the Scalene Muscles

This tutorial discusses the scalene muscles, which are three paired cervical muscles extending from the cervical vertebrae to the upper ribs. The video covers their origins, insertions, and functions, including their role as accessory muscles of inspiration. It also explains the interscalene triangle, through which the subclavian artery and brachial plexus pass. The tutorial concludes with a call to explore more anatomy resources on Kenhub.
