In this video lecture educator describes Humerus Upper Arm Bone in detail. Lecture is started with the introduction of Humerus. The skeletal support for the arm is a long bone which is called Humerus. The Humerus articulates with the scapula at the shoulder joint and with the radius and ulna at the elbow joint. Parts of the Humerus are Upper end, Shaft, and the Lower End which are then explained in detail. The Condyle of Humerus have two parts one is Capitulum and other one is Trochlea. The two epicondyles lie adjacent and somewhat superior to the trochlea and the capitulum they are The Medial Epicondyle and The Lateral Epicondyle. Then the educator explains the three Fossae that are The Radial Fossa, The Coronoid Fossa, and The Olecranon Fossa and functions of three Fossae.
Bicipital Groove, Deltoid Tuberosity and the Lower Half of Anterior Surface of Shaft are the Attachments on Humerus, Brachialis Origin, Coracobrachialis, Deltoid Lateral Head of Triceps Muscle, Spiral Groove, Medial Head of Triceps, Anconeus, and the Capsule of Elbow Joint are the Attachments on the Shaft of Humerus. Fractures of Humerus are Humeral Head Fracture, Greater Tuberosity Fractures, Lesser Tuberosity Fractures, Surgical Neck Fractures, and Fractures of the Shaft of Humerus.
