Hadith 1

to the muscle of the head, and the second pair emerges from what is between the healed hole in between the first vertebra. And the second, it connects to the skin of the head, giving it a sense of touch, and the muscles of the neck and the muscles of the cheek, giving them movement. The third pair comes out from the healed foramen between the second and third vertebrae and is divided into two parts Some of it becomes the muscle that moves the cheek, and some of it separates into the muscle between the shoulders. The fourth originates between the third and fourth vertebrae, and is divided into two parts, one of which is in the muscle in the back, and the other is taken to the front and separated in the muscle that is placed parallel to it and above it. And the fifth comes out between the fourth and fifth vertebrae and is divided into sections, some of which reach the eyebrows, some of them to the muscle that moves the head and neck, and some of them to the shoulder muscle. The sixth, seventh, and eighth come out between the fifth, sixth, seventh, and eighth, and some of them are divided into the muscle of the head and neck, and some of them are in the muscle of the shin and the veil, except for the eighth, because nothing comes of the eyebrows from it, and some of it reaches the upper arm and the arm, and to the shoulder. And from the sixth it connects partly with the muscle of the shoulder and moves the humerus and partly with the muscle of the upper humerus, and it attains the sense. From the seventh part of it reaches the muscle of the humerus and through it the movement of the arm, and part of it separates in the skin of the remaining humerus and sensation reaches it, and some of it comes to be in the muscles of the forearm and moves the palm. And the ninth pair comes out between the eighth and ninth vertebrae, and they are the first vertebrae in the back, and some of it divides in the muscle that is between the ribs, and some of it is in the muscle of the backbone, and some of it goes down to the heel and oozes into it, and there is some feeling and some movement in it. The tenth comes out between the ninth and tenth vertebrae, and part of it becomes to the skin of the humerus, giving it sensation, and the rest of it is divided, so a part is taken from it to the front, and it separates into the muscle that is on the abdomen, and some of it is separated into the muscle of the back and the shoulder. To the nineteenth pair. And the twentieth pair comes out from between the nineteenth and twentieth vertebrae, which is the first of the lower back vertebrae, and according to this analogy, until five pairs come out from between these vertebrae, and some of them become in the feet, so they disperse in the muscle that is on the lower back, and some of them separate in the muscle that is on the back. The three pairs mingle with superior nerves descending from the brain. And the two pairs that are under these three pairs, from which large people descend to the leg until it reaches the tip of the foot, and three pairs come out from the sacrum vertebrae and fuse with the lumbar and descend from it to the leg and disperse into the muscles that are there, and three pairs come out of the coccyx marrow with joint exits such as the neck, and one of the end of it is that the last vertebrae of it has no hole in it other than the median, and all of it radiates into the penis, the buttock muscle, the bladder, the uterus, the abdominal membrane, or into the muscle placed near these places. As for the ribs, they are twenty-four bones on each side, twelve, all of them convex, the longest and the middle being seven of them. One of its ends is connected from behind to the vertebral column by appendages from it and by the vertebrae of the vertebrae, and the connection with the ligaments and the occurrence of double joints and from the front of the sternum bones with cartilaginous h
