Throttle channel

A longitudinal muscle groove in the lower neck area in mammals is called a throttle groove ( Latin : sulcus jugularis ) . It is bounded on the abdomen by the sternocleidomastoid muscle and on the back by the brachiocephalicus muscle . In the direction of the entrance to the chest, the throttle groove ends in the throttle pit ( fossa jugularis or jugulum ), which lies between the two clavicles and is bordered at the bottom by the upper edge of the sternum . To the side of the throttle pit is the overclavicular pit (" salt barrel " or Latin : Fossa supraclavicularis ).
The throttle groove is partially covered by the muscles of the neck skin and therefore not easily visible in all places. Especially in domestic pigs it is not visible through the thick rind.
In the throttle groove, the external jugular vein runs directly under the skin. It is also known as the jugular vein . When dammed, it more or less protrudes and is therefore often used by veterinarians for intravenous injection and blood sampling .
The prick is placed in the throttle pit for bleeding during slaughter or for slaughtering . The large vascular trunks at the entrance to the breast are opened, so that rapid, fatal blood loss occurs.
