Scalene anterior Muscle is a group of three pairs of muscles in the lateral neck, namely the anterior scalene. It is located deeply just behind the Sternocleidomastoid muscle. The brachial plexus and subclavian artery runs between the anterior and middle scalene muscles. This provides an important anatomical locations for anaesthetics to do an interscalene block….
Introduction Scalene Muscle is a group of three pairs of muscles in the lateral neck, namely the anterior scalene, middle scalene, and posterior scalene. The cervical tract is laterally positioned and the scalene muscles are deep. Because the brachial plexus and the cervical plexus are involved in their function, their innervation is complex. Their functions…

Inferior Pharyngeal Constrictor Muscle Anatomy The Inferior pharyngeal constrictor, the thickest of all three constrictors, arises from the sides of the cricoid and thyroid cartilage. Similar to the superior and middle pharyngeal constrictor muscles, This Muscle Nerve supply is the vagus nerve (cranial nerve X), specifically, by branches from the pharyngeal plexus and by neuronal…
