Blood in urine (haematuria) Introduction. Finding blood in your urine can be very frightening and must be investigated by a doctor, but it's not usually a sign of anything life-threatening. If you notice bright red blood in your urine, or if your urine has turned red or brown because it has blood in it, see your GP.
An inside look at the structure of the elbow. #. Advertisement. Advertisement. The elbow is where the two bones of the forearm â the radius on the thumb side of the arm and the ulna on the pinky finger side â meet the bone of the upper arm -- the humerus. The lower end of the humerus flares out into two rounded protrusions called epicondyles, where muscles attach.
The bones of the elbow are the humerus (the upper arm bone), the ulna (the larger bone of the forearm, on the opposite side of the thumb), and the radius (the smaller bone of the forearm on the same side as the thumb). The elbow itself is essentially a hinge joint, meaning it bends and straightens like a hinge.he bones of the elbow are the humerus (the upper arm bone), the ulna (the larger bone of the forearm, on the opposite side of the thumb), and the radius (the smaller bone of the forearm on the same side as the thumb).
