Presternal region
Regio presternalis [prae-]
Definition
The presternal region corresponds to the most cranial and median portion of the ventral thoracic wall, located immediately in front of the sternal manubrium at the junction between the neck and the thorax. It covers the anterior part of the sternum and forms a transition zone between the cervical and thoracic structures.
Anatomically, this region includes the cranial surface of the manubrium, the superficial and deep cervical fasciae, portions of the sternohyoid, sternothyroid, and sternocephalic muscles, as well as superficial vascular structures, including the caudal extremity of the external jugular vein.
