What is a breast belt?

Pectoral belt, also called shoulder belt, consists of a set of bones that form the shoulder. In human beings it includes two collarbone bones and two bones of the shoulder blade. The clay is also referred to as a collar and a scoop, a blade. Some species have three bones in the breast belt. For example, animals such as dogs and horses have only bones of the shoulder blade, but no collarbone bones.

Although the belt generally refers to a complete ring or whole circle, the breast belt consists of a complete circle. Two collarbone bones are divided into the front of the breast bones, also referred to as thoracic bones. In addition, there is a space separating two bones of the shoulder blade on the back of the breast belt. Human beings have only joints that connect the belt of the shoulder of the axial skeletal structure, 80 bones in the head and chest of the human body. These joints are called sternoclavicular joints and are located on both sides.

There are no joints that connect the chest cage, also called a ribbed cage, to each shoulder blade. However, the muscles that connect two allow the pectoral outline bones to have a significant range of movement. Species that only have the bones of the shoulder blade have a muscle connection, but no joints connecting the foreleg and chest, part of the animal's body located between the head and the abdomen.

The keyboard, one of the bone sets that form the breast belt, is slim and in the shape of the letter S. It connects the bones at the top of the arm with the body trunk. In addition, the piano keeps the breast belt by keeping the shoulder in the right environment and outside the trunk area. This allows more freedom movement.

Scapula, the second set of bones that form a breast belt, are flat, triangular bones. They are located on the second to seventh ribs on the back of the rib cage. Several muscles are attached to the bone of the blade and one edge has a thin, hollow space called Glenoid cavity. Here is located the upper part of the humerus, the bone of the upper arm. A thin border that leadsAlong the surface of the shoulder blade, it forms the spine of the bone that provides the force of the shoulder blade to prevent breaking or bending.
