Where does the lateral end of the clavicle articulate?

Where does the lateral end of the clavicle articulate?

acromion
Laterally, the clavicle articulates with the acromion, forming the acromioclavicular ligament (AC joint).

What is the lateral attachment of the clavicle?

[4] The lateral third of the clavicle serves as attachments for the deltoid and trapezius muscles anteriorly and posteriorly, respectively. Inferiorly the conoid and trapezoid components of the CC ligament provide stability between the clavicle and the coracoid process of the scapula.

What muscle attaches to the lateral end of the clavicle?

The trapezius muscle
Two muscles are attached to the lateral third of the clavicle: The trapezius muscle, which is attached along the posterior surface of the lateral third of the clavicle. The deltoid muscle, where the anterior portion of the muscle is attached to the periosteum at the anterior surface of the bone.

What is the lateral tip of the shoulder?

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. There are some sex differences in the morphology of the clavicle. In women, the clavicle tends to be shorter, thinner, and less curved.

What is the medial end of the clavicle?

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.

Which region of the clavicle is known as the acromial end?

Extending laterally from the spine is a flattened and expanded region called the acromion or acromial process. The acromion forms the bony tip of the superior shoulder region and articulates with the lateral end of the clavicle, forming the acromioclavicular joint (see Figure 8.1.

What is the acromial end of the 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.

Which muscle originates on the lateral clavicle?

Anteriorly, the pectoralis major originates on the medial two thirds of the clavicle and the deltoid on the lateral third. Posteriorly, the trapezius muscle inserts onto the lateral third of the clavicle. The clavicular head of the sternocleidomastoid muscle originates on the superior surface.

Why do I have pain in my clavicle?

Collarbone pain can be caused by a fracture, arthritis, a bone infection, or another condition related to the position of your clavicle. If you have sudden collarbone pain as the result of an accident, sports injury, or other trauma, get to an emergency room.

Which bone is your clavicle laterally articulated with?

The scapula and clavicle articulate with the bones of the thorax at one point only, here, at the sternoclavicular joint. The lateral end of the clavicle articulates with this projection on the scapula, the acromion, forming the acromio-clavicular joint.

Where is the lateral border of the scapula?

The lateral border (axillary border) is the thickest of the three borders of the scapula. It begins above at the lower margin of the glenoid cavity, and inclines obliquely downward and backward to the inferior angle. Immediately below the glenoid cavity is a rough impression, the infraglenoid tuberosity,about 2.5 cm.

What is the acromial end of clavicle?

What is the most lateral structure of the scapula?

The lateral angle of the scapula is the location of the glenoid cavity; this is where the humeral head articulates with the scapula. At the margins of this cavity, a fibrocartilagenous structure called the glenoid labrum acts to deepen the cavity as to accommodate more of the humeral head.

Which end of the clavicle connects to the acromion process?

lateral end
The lateral end of the clavicle articulates with this projection on the scapula, the acromion, forming the acromio-clavicular joint. Apart from this one very movable bony linkage, the scapula is held onto the body entirely by muscles.

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.

Which muscle originates on the lateral clavicle the top of the acromion?

Deltoid muscle
