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 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 ...
This is located posteroinferior to the deltoid tuberosity. The inferior boundary of the spiral groove is continuous distally with the lateral border of the shaft. Radial groove continuing as the lateral border of shaft of the humerus. The nutrient foramen of the humerus is located in the anteromedial surface of the humerus.
It is located on the center of the lateral border of the humerus bone. [1] ... text in the public domain from page 211 of the 20th edition of Gray's Anatomy (1918)
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 ...
In cursorial (running) animals such as the pronghorn, the deltoid tubercle is located about a quarter of the way down the shaft, which allows for rapid but relatively weak limb flexion and extension. In natatorial (swimming) animals such as the North American river otter , the tubercle is located nearly halfway down the shaft, which allows for ...
In human anatomy of the arm, the capitulum of the humerus is a smooth, rounded eminence on the lateral portion of the distal articular surface of the humerus. It articulates with the cup-shaped depression on the head of the radius , and is limited to the front and lower part of the bone.
The humerus has two tubercles, the greater tubercle and the lesser tubercle. These are situated at the proximal end of the bone, that is the end that connects with the scapula . The greater/lesser tubercule is located from the top of the acromion laterally and inferiorly.
