Ulna Anatomy

It extends from the lateral side of the elbow to the thumb side of the wrist and runs parallel to the ulna. Anatomy of the ulna bone different parts of ulna and the joints formed by them.

Ulna Bone Structure Attachments Functions Clinical

It joins with the humerus on its larger end to make the elbow joint and joins with the carpal bones of the hand at its smaller end.

Ulna anatomy. The ulna acts as the stabilising bone with the radius pivoting to produce movement. It has two heads one originates from the medial epicondyle of the humerus the other from the radius. The distal radius where it fits into the ulnar notch.

Specifically the ulna joins articulates with. Trochlea of the humerus at the right side elbow as a hinge joint with semilunar trochlear notch. The radius or radial bone is one of the two large bones of the forearm the other being the ulna.

Ulna inner of two bones of the forearm when viewed with the palm facing forward. The muscle splits into four tendons at the wrist which travel through the carpal tunnel and attaches to the middle phalanges of the four fingers. The other shorter bone of the forearm is the radius the upper end of the ulna presents a large c shaped notchthe semilunar or trochlear notchwhich articulates with the trochlea of the humerus upper arm bone to form the elbow joint.

The ulna is located on the opposite side of the forearm from the thumb. The radius is shorter and smaller than the ulna. At the wrist the radius articulates with the proximal row of carpal bones to form an ellipsoidal joint.

The radius near the elbow as a pivot joint this allows the radius to cross over. Distally the ulna articulates with the radius forming the distal radio ulnar joint. This fibrous connective tissue consists of five ligaments which not only help support and strengthen the forearm bones but they also provide attachment points for some of the forearm muscles.

The ulna is a long bone in the forearm. The ulna is the longer larger and more medial of the lower arm bones. It lies medially and parallel to the radius the second of the forearm bones.

Together with the radius the ulna enables the wrist joint to rotate. Many muscles in the arm and forearm attach to the ulna to perform movements of the arm hand and wrist. The long bone can be divided into three parts the proximal or upper end shaft and the distal or lower end 6.

Movement of the ulna is essential to such everyday functions as throwing a ball and driving a car. Proximally the ulna articulates with the humerus at the elbow joint. Introduction to the radius and ulna bones anatomy the junction between the humerus and radius is a hinge joint which permits flexion and extension movements front to back of the elbow.

The muscle is a good anatomical landmark in the forearm the median nerve and ulnar artery pass between its two heads and then travel posteriorly. The ulna is one of two bones that give structure to the forearm. Ulna bone anatomy also called ulnar bone.

This tissue runs along the border of the radius and ulna. It is a long bone prism shaped and slightly curved longitudinally.
