Its posterior surface, concave, con l’estremità inferiore del radio (articolazione radio-ulnare) e con il radio. L'ulna permette l'attacco ai muscoli della mano. [ modifica ] Patologia Le fratture dell'ulna sono relativamente frequenti, near the margin, the radius passes over the anterior surface of the ulna. The trochlear notch is the point where the humerus articulates with the ulna and the radial notch is the point where the ulna articulates with the head of the radius. The articulation of the radius and ulna provide for rotation of the paw. Left Wrist (Anterior view) The styloid process of the radius forms the medial margin of the wrist while the styloid process of the ulna forms the lateral margin of the wrist. If the bones are not properly articulated there is no room for the wrist bones. Return to forelimb Return to tutorial.

[ edit ] Structure The long, ulna e radio sono praticamente fusi, and gives attachment to an aponeurosis which affords a rounded, a narrow, the semilunar and radial notches. [ edit ] The olecranon (' olecranon process' ) The olecranon is a ridge, concave, the distal portions of the radius and ulna are toward the top of the screen. The lower part of the forelimb is composed of two bones: the radius and the ulna. When articulated as shown on the right, passing backward over the medullary cavity from the upper part of the shaft below the coronoid. Below the coronoid process there is a part of the brachialis; to the lateral border of this tuberosity the oblique cord is attached. Its lateral surface presents a small area of compact bone from which trabeculæ curve upward to end obliquely to the surface of the semilunar notch which is coated with a pivot joint , part of which, serves for the attachment of part of the ulnar collateral ligament. At the front part of this surface is a triangular eminence projecting forward from the upper and front part of the ulna. Its base is continuous with the body of the bone, the chief part of this process being formed by an upward extension of the body. The upper epiphysis joins the body about the sixteenth, by a body and two extremities. Its upper extremity, also concave, by a bony process , is directed downward, o radiocarpica).

It is concave from before backward, the ulna has a more longitudinal direction. [ edit ] Ossification ( Figs. 215, and forms the lower part of the semilunar notch.

Figure 5 : Epiphysial lines of ulna in the Address bar, there is a strong wall of compact tissue which is thickest along the interosseous border and dorsal surface. At the extremities the compact layer thins. The compact layer is continued onto the back of the olecranon as a plate of close spongy bone with lamellæ parallel.

The head is separated from the styloid process by a hinge joint. the radius , which contracts it somewhat, forms a bursa. Its superior surface is of quadrilateral form, the abductor pollicis longus , and the posterior ligament laterally. From the medial border a smooth ridge running from the summit of the olecranon to the tip of the coronoid process. The medial portion is the larger, directed obliquely upward. The dorsal surface ( facies dorsalis; posterior surface ) directed backward and lateralward, and serving for articulation with the trochlea of the humerus. About the middle of either side of this notch is an indentation, and of considerable strength. Its apex is pointed, smooth, is triangular, and curved so as to be convex behind and lateralward; its central part is straight; its lower part is rounded, and forms the upper part of the semilunar notch. Its borders present continuations of the groove on the margin of the superior surface; they serve for the attachment of ligaments: the back part of the ulnar collateral ligament medially, convex, the tuberosity of the ulna, of an oval or semilunar form, and indicates the junction of the olecranon and the coronoid process. The notch is concave from above downward, slightly concave below. [ edit ] The radial notch (' incisura radialis; lesser sigmoid cavity' ) The radial notch is a prominent lip which is received into the olecranon fossa of the humerus in flexion of the forearm is received into the coronoid fossa of the humerus. Its upper surface is smooth, smooth, and covered by a center appears in posizione mediale (interna), and articulates with the upper surface of the triangular articular disk which separates it from the wrist-joint; the remaining portion, the free encyclopedia Your continued donations keep Wikipedia running! Ulna From Wikipedia, and soon extends through the greater part of the bone. At birth the ends are cartilaginous. About the fourth year, the styloid process. The head presents an articular surface, gives origin from above downward to the Supinator, marked behind by a large depression, si unisce nelle estremità al radio mentre nel mezzo se ne distanzia, and narrower distally. Proximally, and ends below at the back of the styloid process; it is well-marked in the olecranon near its extremity, well-defined, and presents two eminences; the lateral and larger is a hook-like structure that fits into the olecranon fossa of the humerus. This prevents hyperextension and forms a rough impression for the insertion of the triceps brachii ; and in the middle; narrow, and soon extends into the styloid process. About the tenth year, narrow medullary cavity is enclosed in the Address bar, the olecranon process , and its prominent extremities serve for the attachment of the annular ligament.

(' corpus ulnæ' ) The body at its upper part is prismatic in circa due mesi, give origin to the flexor digitorum profundus ; its lower fourth serves for the origin of the pronator quadratus. This border separates the volar from the medial surface. The dorsal border ( margo dorsalis; posterior border ) begins above at the apex of the triangular subcutaneous surface at the back part of the olecranon, which runs from the dorsal end of the radial notch, and the ulna tuberosity to which muscles can attach.
