Study Notes

Clavicular Articulations

The sternal end of the clavicle articulates with the manubrium of the sternum, forming the sternoclavicular joint.
The acromial end of the clavicle articulates with the acromian process of the scapula, creating the acromioclavicular joint.

Joint Formation

Sternal end of the clavicle and manubrium of the sternum create the sternoclavicular joint.
Acromial end of the clavicle and acromian process of the scapula form the acromioclavicular joint.

Humeral Articulations

The head of the humerus articulates with the glenoid fossa of the scapula, forming the glenohumeral joint.
The trochlea of the humerus articulates with the trochlear notch of the ulna.
The capitulum of the humerus articulates with the head of the radius.

Radioulnar Connections

The head of the radius articulates with both the capitulum of the humerus and the radial notch of the ulna.
The radial notch of the ulna is the articulation point for the head of the radius.

Elbow Joint

The olecranon process of the ulna articulates with the olecranon fossa of the humerus, crucial for elbow movement.

Siding Bones

Scapula: Identify the spine (posterior surface) and glenoid fossa (lateral surface) to side the scapula.
Clavicle: The acromial end indicates lateral orientation, while the medial end connects to the sternum; the inferior surface is bumpy.
Humerus: The head (medial side) and olecranon fossa (posterior surface) are key features for siding.
Ulna: The radial notch (lateral side) and trochlear notch (anterior surface) help in identifying orientation.
Radius: The radial tuberosity (anterior surface) and styloid process (lateral surface) guide the siding process.
