Hadith 1

o it and brings it close to it, and a branch emerges from it to the outside. Parallel to the armpit, it comes out of a great branch. The hand comes from the side of the armpit, which is the section (called) A’ Basleeq’. When the clavicle aligns the middle of it with the place of the core, it is divided into two parts, one of which is to the right and the other to the left, and each of these two parts is divided into two parts. The rest was divided into two parts on each side, and one of them passed deep and ascending in the neck until it entered the cranium and irrigated the parts of the brain and the membranes there, and as it passed through the neck until it enters the brain, small branches diverge from it and irrigate the organs in the neck, and this part is called the deep jugular. As for the second, it passes by an ascension on the outside until it splits in the face, head, neck and nose, and waters all these parts. It is the external jugular, and it diverges from the scapular vein as it passes through the humerus watering the outer part of the upper arm, and branching out from the armpit, watering the inner part. And when the scapular vein and the axillary vein close to the elbow joint are divided, then the splitting of the scapular vein mixes with a part of the axillary vein and unites with it, so that at the elbow is the vein called the kohl, and the second part of the sections of the scapular vein extends on the outside of the forearm and is then attached to the upper ulna and this section is the tendon of the arm and a section of the axillary vein, which is the smallest place, which passes through the inner side of the forearm until it reaches the head of the lower ulna, and from some of its branches the vein between the little finger and the ring finger, called the osculum. As for the section that takes to the lower part of the body, it attaches to the vertebrae, taking it down, and branching out from it. Then two great branches diverge from it, entering the cavity of the kidneys, then two branches that go to the two females. Then two veins diverge from it at each vertebra. They pass in the two sides and water the organs close to it from what was inside, such as the uterus and bladder. And whatever was outside of it like the ribs of the abdomen and the flanks, until when it reached the end of the vertebrae, it was divided into two parts, and one of them was taken to the right leg and the other to the left. A branch of it irrigated the muscle of the thighs, some of which were deep, irrigated the deep muscle, and from them is the phenomenon of watering the external muscle, even when it reached the two-knee epiphysis, it was divided into three sections, and a part of it passed in the middle and watered with a branch that has all the muscles of the leg inside and outside, and a section passed on the inside side of the leg until it appears at the inner heel, which is the saphenous. And the other type passes through the visible side of the leg and is lower to the side of the outer heel, which is the sciatica. When it reaches the foot, it diverges from each of these two separate branches in the foot, so the branches in the foot are in the pinky side. The ring finger is from the branch of the sciatica, and the one in the thumb is from the branch of the sap. As for the gallbladder, it is a neural sac that attaches from the liver to the side of the stomach and is placed on its largest appendage. It is of a single layer, woven from the three types of fibrous, and it has two outlets, one of which is connected to the concavity of the liver, and with it the bile is attracted to it, and the other is branched and connected to the upper intestine and to the lower stomach. And by it, parts of the bile rush to it to wash it away from refuse and alert it to the need and rise to defecate as it has passed, and the gallbladder is not for some animals such as camels bec
