The body or shaft of the humerus is triangular to cylindrical in cut section and is compressed anteroposteriorly. It has 3 surfaces, namely: It has 3 surfaces, namely: Anterolateral surface: the area between the lateral border of the humerus to the line drawn as a continuation of the crest of the greater tubercle.
English: The humerus is the (upper) arm bone. It joins with the scapula above at the shoulder joint (or glenohumeral joint) and with the ulna and radius below at the elbow joint. Notice: When the arm is spun so that the thumb point to the outside of the body, meaning the palm of the hand looks forward then it is said the hand is supinated. But ...
The anatomical neck of the humerus is obliquely directed, forming an obtuse angle with the body of the humerus. It represents the fused epiphyseal plate. It represents the fused epiphyseal plate. [ 1 ]
English: The anatomical neck is the groove that surrounds the articular surface of the head of the humerus. This is where the joint capsule is attached. The surgical neck however, is a segment present inferior to the humeral head. This acts as a connection between the head and the shaft of the humerus.
The lateral surface of the greater tubercle is convex, rough, and continuous with the lateral surface of the body of the humerus. It can be described as having a cranial and a caudal part. [1] Between the greater tubercle and the lesser tubercle is the bicipital groove (intertubercular sulcus). Rear view of the greater tubercle of right humerus
The humerus is one of the three long bones of the arm. It joins with the scapula at the shoulder joint and with the other long bones of the arm, the ulna and radius at the elbow joint. [6] The elbow is a complex hinge joint between the end of the humerus and the ends of the radius and ulna. [7]
The list below describes such skeletal movements as normally are possible in particular joints of the human body. Other animals have different degrees of movement at their respective joints; this is because of differences in positions of muscles and because structures peculiar to the bodies of humans and other species block motions unsuited to ...
The trochlea has the capitulum located on its lateral side and the medial epicondyle on its medial. It is directly inferior to the coronoid fossa anteriorly and to the olecranon fossa posteriorly. In humans, these two fossae, the most prominent in the humerus, are occasionally transformed into a hole, the supratrochlear foramen , [ 2 ] which is ...
