What is the end of the scapula called?

What is the end of the scapula called?

The scapula has a triangular body with three main processes coming off the body. On the posterior side is the spine of the scapula that ends in the acromion process, which articulates with the lateral end of the scapula. On the anterior side, facing into the body, is a right-angled process called the coracoid process.

Where is sternal end located?

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 is the sternal end of the clavicle called?

medial
Bony landmarks 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 is the scapula to the sternum?

Clavicle. The clavicle, commonly called the collarbone, is an S-shaped bone that acts like a mechanical rod that links the scapula to the sternum (Fig. 4.3). The flattened lateral portion—called the acromial end—articulates with the acromion of the scapula, forming the acromioclavicular (AC) joint.

Is scapula appendicular or axial?

The appendicular skeleton is everything else. It’s everything that attaches on to the axial skeleton. Think “appendages”. The pelvis, femur, fibula, tibia and all of the foot bones as well as the scapula, clavicle, humerus, radius, ulna and all of the hand bones are classified as appendicular.

What is the Acromial end of clavicle?

The lateral end is also known as the acromial end. It is flat from above downward. It bears a facet that articulates with the shoulder to form the acromioclavicular joint. The area surrounding the joint gives an attachment to the joint capsule.

What 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 sternal end mean?

Sternal or medial end (extremitas sternalis) is the rounded end of the clavicle that articulates with the manubrium of the sternum. [

What does the sternal end of the clavicle articulate with?

manubrium
The medial end, known as the sternal end of the clavicle, has a triangular shape and articulates with the manubrium portion of the sternum. This forms the sternoclavicular joint, which is the only bony articulation between the pectoral girdle of the upper limb and the axial skeleton.

Where is Conoid tubercle located?

clavicle
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 is sternal anatomy?

Sternum. The sternum is the bone that lies in the anterior midline of our thorax. It forms part of the rib cage and the anterior-most part of the thorax. Its functions are to protect the thoracic organs from trauma and also form the bony attachment for various muscles.

What is sternal region?

The sternum or breastbone is a long flat bone located in the central part of the chest. It connects to the ribs via cartilage and forms the front of the rib cage, thus helping to protect the heart, lungs, and major blood vessels from injury.

What is the bony process above the scapula called?

This bony process articulates (forms a joint) with the acromial end of the clavicle, forming the acromioclavicular joint, a plane joint that allows gliding movements. Supraspinous Fossa – The supraspinous fossa is a depression above the spine of the scapula.

Where does the costoclavicular ligament attach to the scapula?

Inferior surface near the acromial end of the clavicle where the conoid ligament attaches with the scapula. Inferior surface near the sternal end of the clavicle where the costoclavicular ligament attaches with the first rib.

What is the superior angle of the scapula?

Superior Angle – At the superior end of the scapula, a small triangular projection is formed at the junction of the superior border and medial border, called the superior angle, which allows fibers from the levator scapulae to attach. It will be easy to locate these three borders if you remember your directional terms:

Where does the clavicle articulate with the sternum?

Remember, medial means toward the midline of the body, and the sternum is the breastbone. This part of the clavicle is going to articulate with the manubrium of the sternum. The scapula, also called shoulder blade, is a triangle-shaped bone on the posterior side of the body that forms the posterior part of the pectoral girdle.
