Where does the acromial end of the clavicle articulate?

Where does the acromial end of the clavicle articulate?

acromion of the scapula
The acromial end of the clavicle articulates with the acromion of the scapula at the acromioclavicular joint. This end is also anchored to the coracoid process of the scapula by the coracoclavicular ligament, which provides indirect support for the acromioclavicular joint.

What bone and bone feature articulates with the acromial end of the clavicle?

scapula
The lateral or acromial end of the clavicle articulates with the acromion of the scapula, the portion of the scapula that forms the bony tip of the shoulder.

What bone does the clavicle articulate with?

The clavicle articulates with the scapula here, at the tip of the acromion.

What articulates with the acromion process of the clavicle?

The scapula articulates with the clavicle through the acromion process, a large projection located superiorly on the scapula forming the acromioclavicular joint. The scapula also articulates with the humerus of the upper arm to form the shoulder joint, or glenohumeral joint, at the glenoid cavity.

What 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?

Description. 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.

How the clavicle curves and articulates with other bones?

Medially, it articulates with the manubrium of the sternum (breast-bone) at the sternoclavicular joint. From the roughly pyramidal sternal end, each clavicle curves laterally and posteriorly for roughly half its length. It then forms a smooth posterior curve to articulate with a process of the scapula (acromion).

What bone does the clavicle articulate with quizlet?

What bones does the clavicle articulate with? The sternum (medially, to form the sternoclavicular joint), and the scapula laterally to form the acromioclavicular joint. You just studied 92 terms!

What are the ends of the clavicle?

The orientation of the clavicle can be distinguished by its ends: a broad, flat acromial end (referred to as the lateral third); and a round pyramidal-like sternal end (referred to as the medial two-thirds). Each end has unique bony landmarks, depending whether the superior or inferior surface of the bone is viewed.

Is acromion and acromion process the same thing?

In human anatomy, the acromion (from Greek: akros, “highest”, ōmos, “shoulder”, plural: acromia) is a bony process on the scapula (shoulder blade).

What has an acromial end?

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 the end of the clavicle called?

acromial end
The orientation of the clavicle can be distinguished by its ends: a broad, flat acromial end (referred to as the lateral third); and a round pyramidal-like sternal end (referred to as the medial two-thirds).

What muscles attach to the clavicle?

The human clavicle, or collarbone, has six muscles directly attached to it. At the front top are attached the trapezius and sternocleidomastoid muscles. At the bottom front and back are attached the deltoid and pectoralis major. To the inside is the subclavius.

Where does the clavicle end?

The clavicle is an elongated, S-shaped bone that rests horizontally at the sternum across the upper part of the ribcage, and the acromial end of the scapula.

What are the attachments of the clavicle?

The clavicles, along with the scapulae , form the pectoral girdle that attaches the bones of the arm to the trunk. In fact, the sternoclavicular joints are the only bony attachments between the pectoral girdles and the bones of the axial skeleton.

What are the bony landmarks of the clavicle?

Clavicle Bone Marking: Sternal or medial end (extremitas sternalis) is the rounded end of the clavicle that articulates with the manubrium of the sternum. Acromial or lateral end (extremitas acromialis) is the flattened end of the clavicle that articulates with acromion of the scapula .
