Like most countries in Europe, Summer (Daylight-Saving) Time is observed in UK Time, where the time is shifted forward by 1 hour; 1 hours ahead of Greenwich Mean Time (GMT+1). After the Summer months the time in UK Time is shifted back by 1 hour to Western European Time (WET) or (GMT).
The elbow joint has three different portions surrounded by a common joint capsule. These are joints between the three bones of the elbow, the humerus of the upper arm, and the radius and the ulna of the forearm.
Elbow joint. The elbow joint consists of three bones: the humerus, the ulna, and the radius. These bones create three articulations â the ulnohumeral, the radiohumeral, and the proximal radioulnar â that provide flexion, extension, and forearm rotation.he configuration of the elbow joint allows for flexion and extension of the forearm. When the elbow is fully extended and the forearm is supinated, the axis of the ulna creates an angle of approximately 170 degrees with the axis of the humerus.
