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.

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.
Muscles, ligaments and tendons are the structural support for the elbow joint. The elbow is the location of origin for the muscle of the forearm, the common extensor muscles at the lateral epicondyle and the common flexor muscles at the medial epicondyle of the humerus.The biceps and brachioradialis muscles also attach to the elbow joint region.ateral epicondylitis or âtennis elbowâ is an overuse syndrome of the common extensor tendon of the forearm. This syndrome has been documented as one of the most prevalent disorders of the arm. This injury is seen as a degenerative syndrome of the extensor tendon at the lateral epicondyle.
