In addition, during respiration, the ribs move forward allowing the lungs to fill with air. The ribs extend to the upper abdomen, offering protection to the liver and spleen. Ribs protect the heart, To the lungs and to the aorta (one of the main arteries of our body). All these pairs are connected to the spine, while only ten of these are connected to the sternum. The ribs are composed of twelve pairs of bones. Bottom, called xiphoid tip or appendix.Top, which is called manubrio or mango.In the sternum, three parts are distinguished: The two lower pairs, unlike the rest, are not connected in any way to the sternum, so they are called"floating ribs". The first seven pairs of ribs are connected directly to the sternum Pairs 8, 9 and 10 are attached to the sternum through cartilage. The sternum is shaped like a tie and is in the center of the chest. In the thorax are three bony structures that belong to the classification of long bones, namely: the ribs, the sternum and the shoulder blades. The sphenoids are located in the lower part of the skull, at the base, and present a cavity in which the pituitary is located. This bone occupies the lower and lateral part of the skull. In this is the occipital foramen, which is an opening that connects the skull to the spine. The occipital bone is located at the back of the skull. The parietal bones are two and are one on each side of the head, between the occipital bone and the frontal bone. Once the brain reaches its maximum size, the sutures close and the bones of the skull merge.Īs the name implies, this bone occupies the entire front of the skull. In infants and children, the bones of the cranial vault are separated by spaces called sutures, which allow the skull to expand as the brain it grows. The bones of the skull are also responsible for forming the eye sockets and nostrils. The main role of the skull is to protect the brain from damage that could be generated by blows or falls. The skull, also called the cranial vault, is composed of a series of bones, including the frontal, parietal, occipital, nasal, temporal, lacrimal and sphenoid bones. Types of flat bones The bones of the skull Likewise, being flattened makes them provide ample areas in which the muscles of the body can be fixed.
This is why they are flattened, since they do the role of shields. The function of flat bones is to protect the internal organs of the body, such as the brain, heart and pelvic organs.
The bones of the skull or cranial vault : Occipital, temporal, sphenoid, frontal, parietal, vomer and lacrimal.Among the flat bones are the following, which I will explain later:
