head of radius
The radius articulates with more of the carpal bones than the ulna.
The olecranon fossa of the humerus articulates with the olecranon process of the ulna when the elbow is extended. This forms the back part of the elbow joint.
The ulna articulates with:the humerus at its proximal end (end closest to the elbow)the radius at its radial notch (near the top part of the ulna) and at the ulnar notch (near the bottom part of the ulna)the wrist (separated by a fibrocartilaginous disc) at its distal end (end closest to the hand)
Proximal migration of the humeral head is movement of the top part of the uppermost arm bone into the shoulder socket.
The clavicle. This bone is normally not consideredto be part of the shoulder an instead a part of the thorax, which is also true. The reason it is part of the shoulder is that it joint part of the scapula to form the soked of the glenohumeral joint.
Those bones are the tarsals, which make the ankle.The distal ends of the tibia and fibula articulate with a single tarsal bone called the talus.footfoottarsal bones
This is called as elbow joint. It is a synovial type of joint. It is actually a joint between humerus and ulna mainly. The radius takes part in the joint passively. This is hinge variety of joint.
Sacrum
Body
One side of the pubis articulates interiorly with the other side of the pubis, joining at the pubic symphysis. Posteriorly it articulates with the sacrum, the Acetabulum proximally articulates with Femur bone. So therefore there are three articulation points for the pelvic girdle.
The clavicle is the shoulder girdle bone that articulates with and transmits forces to the bony thorax. It acts as a strut connecting the scapula to the sternum, allowing for movement and stability of the shoulder joint, as well as helping to transfer forces from the upper limb to the axial skeleton.
The knuckle-like process at the end of a bone is known as an articular surface or articular prominence. It plays a key role in forming joints and allowing for smooth movement between bones. The shape and structure of these articular surfaces vary depending on the type of joint and the specific bones involved.
