What articulates with the manubrium of the sternum?
The manubrium is the most superior region of the sternum and articulates with the clavicles or collarbones and the first pair of ribs. The manubrium is the thickest portion of the sternum as it carries the greatest physical load.
Which of the following bones is the anterior bone that articulates with the manubrium of the sternum at the sternoclavicular joint quizlet?
This part of the clavicle is rounded and articulates with the manubrium of the sternum. 5. The following is a bone marking on the clavicle that serves as an attachment site.
What is the articulation of the sternum?
The manubriosternal articulation is that between the upper part of the sternum and the manubrium. The joint is cartilaginous, with a hollow disc in its centre, and is strengthened by the sternocostal ligaments and longitudinal fibrous bands. About 7° of movement occurs at the joint in association with breathing.
What is anterior to the sternum?
The sternum connects the ribs via the costal cartilages forming the anterior rib cage. The manubrium is the broad superior segment, the body is the middle portion, and the xiphoid process is a narrower distal segment forming the partial T-shape.
Which part of the clavicle articulates with the 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.
What does the manubrium articulate with on its superior border?
The manubrium forms the expanded, superior end of the sternum. It has a jugular (suprasternal) notch, a pair of clavicular notches for articulation with the clavicles, and receives the costal cartilage of the first rib.
What part of the clavicle articulates with manubrium?
At its rounded medial end (sternal end), it articulates with the manubrium of the sternum (breastbone) at the sternoclavicular joint. At its flattened lateral end (acromial end), it articulates with the acromion, a process of the scapula (shoulder blade), at the acromioclavicular joint.
Which part of the clavicle articulates with the manubrium *?
What is the Manubrium?
The manubrium is the most massive, thickest, and squarest of three main sternal elements. It is the superior-most element of the sternum and is the widest part of this bone. b. Clavicular notches occupy the superior corners of the sternum. It is here that the manubrium articulates with the right and left clavicles.
Where is the Manubrium bone located?
sternum
The manubrium (Latin for “handle”) is the broad upper part of the sternum. It has a quadrangular shape, narrowing from the top, which gives it four borders. The suprasternal notch (jugular notch) is located in the middle at the upper broadest part of the manubrium. This notch can be felt between the two clavicles.
What does the manubrium articulate with?
Manubrium. Inferiorly, the manubrium articulates with the body of the sternum, forming the sternal angle. This can be felt as a transverse ridge of bone on the anterior aspect of the sternum. The sternal angle is commonly used as an aid to count ribs, as it marks the level of the 2nd costal cartilage.
What bone articulates with the sternum?
The sternum(pronounced ˈstər-nəm) is located in the center of the anterior thoracic wall and is also known as the breastbone. It consists of three segments, the manubrium, body, and xiphoid process. The segments fuse to form a long, flat bone. The sternum articulates with the clavicles and costal cartilages of the ribs.
Where is the sternum located in the body?
Sternum Bone Anatomy. Introduction to Sternum Bone Anatomy. The sternum (pronounced ˈstər-nəm) is located in the center of the anterior thoracic wall and is also known as the breastbone. It consists of three segments, the manubrium, body, and xiphoid process.
Where does the xiphoid process articulate with the manubrium?
It articulates with the manubrium superiorly (manubriosternal joint) and the xiphoid process inferiorly (xiphisternal joint). The lateral edges of the body are marked by numerous articular facets (cartilage lined depressions in the bone). These articular facets articulate with the costal cartilages of ribs 3-6.
