What is anterscalenum spatium?

The term "anterscalenum spatium" refers to a specific anatomical space located in the neck, between the anterior scalene muscle and the underlying structures. This space contains important neurovascular structures, including parts of the brachial plexus and the subclavian artery and vein. Its significance lies in its role in the passage of nerves and blood vessels to the upper limb, and it can be involved in conditions like thoracic outlet syndrome. Understanding this space is crucial for surgeons and medical professionals working in the cervical region.
