Hadith 1

eads, and they are called the ribs of the chest because they connect to the sternum and include the viscera of the chest, and five of them are cut without connection to the sternum, shortened, and their heads are connected by cartilages, and they are called the posterior ribs. Rather, it was created to be a protection for the breathing machines that surround it and the tops of the food machines, and for this reason He-azwj Made what surrounds it with the main organ connected to the sternum to be fortified with it from all sides. And what follows the food machinery is made like a guard from behind, where the guard of sight does not perceive it, and it did not connect from in front, rather it moved a little by little in the interruption. And He-azwj Made the top of it the closest distance between its protruding edges, and the bottom of it the farthest distance to gather to protect the food organs from the liver and spleen and other things to expand the place of the stomach so that it would not be compressed when it was filled with food and from blowing. This is the reason for their number, all of them, and their being with a hole in all along with that assisted by pulling a lot of air and permeate the specific muscles in the acts of breathing and other than that. The fifth chapter – regarding the anatomy of the chest, and the abdomen, and what is contained upon it from the viscera and the hands
As for the sternum, it is connected to seven bones on the ribs of the chest. Rather, it was made fragile so that it would be lighter, and the light movements with which it was made easier, for the vapor to dissolve from it and not to become congested in it, and to keep its joints tight so that it would not be pressed by a compressor or an impactor, and the heart and the dagger would be compressed as a shield for the mouth of the stomach. As for the clavicle, it is a bone placed on each side of the top of the sternum, having length and curvature to the lateral side, and concavity to the medial side. One of its heads connects to the arch and the other to the head of the shoulder, to which the shoulder is attached, and to both of them are the humerus, and its other head is wide, and the ascending veins penetrate into its concave into the brain and the nerve descending from it, and it is a protection for them. As for the shoulder, the bone of its lateral end to the roundness tapers from that end and thickens, causing a non-deep dimple, into which the tip of the humerus enters the round. And it has two appendages that prevent the humerus from dislocating, one of them upward and from behind, and it is called the beak of the crow, and it has the ligament of the shoulder with the collarbone and the other to below and from the inside. Then it continues to show the more you look at the medial side so that its adequate inclusion is more until it ends with a round cartilage that connects with it and on its back an appendage like a triangle called the shoulder blade, its base to the lateral side and its angle to the medial so that the surface of the back is not disturbed by stretching and pain of the skin for clashes, which is like a tooth of the vertebrae created for safety. The shoulder was created because the humerus is attached to it, so that it is not attached to the chest, and because it evens out the movements of the hands and does not narrow their space, and that it is a shield and a second protection for the members confined to the chest and replaces the spines and wings of the vertebrae. As for the humerus, it is a round bone like a reed tube, a round, hollow, filled with a marrow, convex to the lateral, concave to the medial, so that the muscles, nerves, and veins that are overlapped over it, and so that the armpits of the human arm are present, and one hand is approaching the other, and its convex upper end enters the fovea of the shoulder.
