Suprasternal notch

As throttle channel (Latin sulcus jugularis ) a longitudinal furrow muscle in the lower neck region is referred to in mammals. It is bordered by the ventral muscle sternocephalicus and move forward through the brachiocephalic muscle. Toward breast input the throttle channel ends in the jugular fossa ( fossa jugularis or suprasternal notch ), which lies between the two clavicles and is bounded below by the upper edge of the sternum. Laterally the jugular fossa is the supraclavicular fossa ( " salt cellar ").

Some of the throttle channel is covered by the neck muscles and skin thereby not equally well visible at each place. Especially in domestic pigs it is not visible through the thick rind.

In the throttle channel, the external jugular vein runs directly under the skin. It is also called a jugular vein. When damming it emerges more or less, and is therefore often used by veterinarians for intravenous injection and blood collection.

In the jugular notch of the needle is set to exsanguination at slaughter or shafts. Here, the major vessels are opened on breast input, so that a rapid fatal blood loss occurs.
