Location of the Heart. Heart is located safely inside the chest cavity which looks like a cage bound by the ribs and breast bone (sternum). The chest cavity is also called as thoracic cavity and it lies between neck and abdomen.
The sternothyroid muscle, also called the sternothyroideus, is in the neck area. The muscle goes from the sternum, or breastbone, to the edge of the thyroid cartilage. It starts in the manubrium sterni, the uppermost part of the breastbone, and inserts into the lamina, or thin layers, of thyroid cartilage, which is located inferior to (behind) the hyoid. It works to depress the larynx, or voice box, which helps create sound.
