The structures passing through the sigmoid notch of the ulna are the radial notch, which accommodates the head of the radius, and the ulnar collateral ligament which attaches to the radial notch.

capitulum and trochlea. Together they make up the condyle.

The ligament you are referring to is the annular ligament, which encircles the head of the radius and attaches it firmly to the ulna. This ligament allows for proper rotation of the radius around the ulna during forearm movements.

The ulnar surface that articulates with the radial head is known as the ulnar notch of the radius. This is a concave area located on the distal end of the radius, where it meets the head of the ulna at the wrist. The articulation between the radial head and the ulnar notch allows for the rotational movement of the forearm, including pronation and supination. This joint is crucial for the overall function and stability of the forearm and wrist.

The semilunar notch, located in the ulna bone of the forearm, serves as the articulation point for the trochlea of the humerus, allowing for the hinge-like motion of the elbow joint. It facilitates flexion and extension of the forearm while also contributing to the stability of the joint. This notch, along with the radial notch, helps maintain proper alignment and movement between the ulna and radius during various arm activities.

The radial head pivots on the capitulum of the humerus and the radial notch of the ulna during movements like turning a doorknob. This pivoting action allows for the rotation of the forearm, enabling pronation and supination. The smooth articulation between these structures facilitates efficient movement and stability in the elbow joint.

There are a couple that I can think of:
1) Between the hand and the arm is the wrist, which is actually made of Radial-Carpal joints and intercarpal joints.
2) The radioulnar joint, of which there are 2:
1 - The distal radioulnar joint is formed between the head of the ulna and the ulnar notch on the distal radius
2 - The proximal radioulnar joint may be considered part of the elbow, but is actually where the radial head articulates with the radial notch of the ulna.

Radial symmetry.
other animals (exept sponges) and other exeption have bilateral symetry. bilateral symmetrical animals have up and down side, and a front and a back leaving left and right the same. radial animals only have an up side and down side, they do not have a fornt and back side.

A jellyfish has radial symmetry. A jellyfish is part of the cnidaria species of animals and they generally have radial symmetry. Radial symmetric organisms are like a pie in terms of their shape. THey have no left or right sides. If you were to turn a radial symmetric animal on its side, it would like the same as it did prior.

At the distal end: the carpels in the hand at the head of the ulna and the radius at the ulna notch of radius. At the proximal end: the trochlea of the humerus at the trochlear notch and coronoid process of the ulna and the head of the radius at the radial notch of the ulna.

The annular ligament stabilizes and encircles the head of the radius, holding it in place against the radial notch of the ulna. This ligament helps maintain the relationship between the radius and ulna during movements of the elbow joint.
