What does sternal end of clavicle mean?
Sternal or medial end (extremitas sternalis) is the rounded end of the clavicle that articulates with the manubrium of the sternum. [
What is the sternal facet of clavicle?
The sternal facet is an articular facet at the end of clavicle, concave from before backward, convex from above downward, which articulates with the manubrium sterni through the intervention of an articular disk.
What type of joint is the sternum and clavicle?
sternoclavicular joint
The sternoclavicular joint is a synovial joint between the clavicle and the manubrium of the sternum. It is the only attachment of the upper limb to the axial skeleton. Despite its strength, it is a very mobile joint and can function more like a ball-and-socket type joint.
What is the joint classification and type of movement for the sternoclavicular joints?
The sternoclavicular joint or sternoclavicular articulation is the joint between the manubrium of the sternum and the clavicle bone. It is structurally classed as a synovial saddle joint and functionally classed as a diarthrosis and multiaxial joint.
Why is my clavicle popping?
Often, collarbone popping is caused by instability or arthritis changes in your SC or AC joints. If your collarbone pops and is painful, improving shoulder movements and strength can be an effective strategy for getting relief.
How can you tell the difference between the acromial and sternal end of the clavicle?
The rounded medial region (sternal region) of the shaft has a long curve laterally and anteriorly along two-thirds of the entire shaft. The flattened lateral region (acromial region) of the shaft has an even larger posterior curve to articulate with the acromion of the scapula.
What is the purpose of the clavicle bone?
The clavicle is a sigmoid-shaped long bone with a convex surface along its medial end when observed from cephalad position. It serves as a connection between the axial and appendicular skeleton in conjunction with the scapula, and each of these structures forms the pectoral girdle.
How is the clavicle attached to the sternum?
The clavicle (collarbone) is an S-shaped bone located on the anterior side of the shoulder. It is attached on its medial end to the sternum of the thoracic cage, which is part of the axial skeleton. The lateral end of the clavicle articulates (joins) with the scapula just above the shoulder joint.
What is the function of the sternoclavicular joint?
The sternoclavicular (SC) joint is a saddle-shaped, synovial joint that serves as the primary skeletal connection between the axial skeleton and the upper limb.
How do you tell if your clavicle is dislocated?
What Does a Dislocated Shoulder or Separated Shoulder Feel Like?
- Intense pain as soon as the injury occurs.
- Tenderness of the shoulder and collarbone.
- Swelling.
- Bruising.
- Deformed shoulder.
How is the sternal end of the clavicle described?
Anatomical Parts. Description. The sternal end (sternal extremity) of the clavicle is triangular in form, directed medialward, and a little downward and forward; it presents an articular facet, concave from before backward, convex from above downward, which articulates with the manubrium sterni through the intervention of an articular disk.
What are the three parts of the clavicle?
The clavicle can be divided into three parts: a sternal (medial) end, a shaft, and an acromial (lateral) end. Sternal end of clavicle The sternal or medial end of the clavicle has a large triangular facet for articulation with the clavicular notch on the manubrium of the sternum.
Which is part of the clavicle anchors the scapula?
Sternoclavicular Joint. The other is the sternoclavicular joint, which is formed by the sternal end of the clavicle and the manubrium of the sternum. This synovial joint is important as it anchors the clavicle and scapula to the axial skeleton.
Where is the articulation of the sternoclavicular joint?
The Sternoclavicular Joint (SC joint) is formed from the articulation of the medial aspect of the clavicle and the manubrium of the sternum.
