How can you differentiate between the sternal end and Acromial end? The flat acromial end of the collarbone is broader than the sternal end. The acromial end has a rough inferior surface that bears a ridge, the trapezoid line, and a slight rounded projection, the conoid tubercle (above the coracoid process).

Which bone has an acromial end and an sternal end?
The clavicleThe clavicle is a tubular, somewhat S-shaped bone. Its medial end (sternal extremity) articulates, via a synovial joint, with the clavicular notch of the manubrium. Its lateral end (acromial extremity) articulates with the acromial process of the scapula.
Where is the acromial end of clavicle?
The clavicle is divided into the sternal or medial end, the shaft or body and the acromial or lateral end. The acromial end presents a small, flattened, oval surface directed obliquely downward, which articulates with the acromion of the scapula.
What is acromial end?
The acromial end (acromial extremity) presents a small, flattened, oval surface directed obliquely downward, for articulation with the acromion of the scapula. The circumference of the articular facet is rough, especially above, for the attachment of the acromioclavicular ligaments.
Where is the sternal end?
The medial end is also known as the sternal end. It is quadrangular and articulates with the clavicular notch of the manubrium of the sternum to form the sternoclavicular joint. The articular surface extends to the inferior aspect for articulation with the first costal cartilage.
What does the acromion look like?
Structure. The acromion forms the summit of the shoulder, and is a large, somewhat triangular or oblong process, flattened from behind forward, projecting at first lateralward, and then curving forward and upward, so as to overhang the glenoid fossa.
What is an acromial?
Medical Definition of acromion : the outer end of the spine of the scapula that protects the glenoid cavity, forms the outer angle of the shoulder, and articulates with the clavicle. — called also acromial process, acromion process.
How is the clavicle connected to the sternum?
The SC joint connects your clavicle (collarbone) to your sternum, which is the large bone down the middle of your chest. This attachment is the only bony joint linking the bones of the arm and shoulder to the main part of the skeleton.
What is conoid tubercle?
The conoid tubercle also known as the coracoid tuberosity (not to be confused with the coracoid process of the scapula) is a bony prominence on the inferior surface of the lateral third of the clavicle.
What type of bone is the acromion?
The acromion is a fairly flat projection of the scapula that curves around from the back to the front of the shoulder. Much of the strong deltoid muscle around the shoulder attaches to the acromion. This bone also gives the shoulder much of its almost squared-off shape.
Is acromion the tip of the shoulder?
Acromion. The roof (highest point) of the shoulder that is formed by a part of the scapula. Tendons. The tough cords of tissue that connect muscles to bones.
