What structure articulates with the manubrium?
This is the anterior bone that articulates with the manubrium of the sternum at the sternoclavicular joint.
What part of manubrium articulates with clavicle?
b. Clavicular notches
b. Clavicular notches occupy the superior corners of the sternum. It is here that the manubrium articulates with the right and left clavicles.
What is the articulation of the sternum?
Sternoclavicular, Manubriosternal, and Sternocostal Joints The medial ends of the clavicles articulate on each side of the sternum at its upper end to form the sternoclavicular joints. The articulations of the first ribs and the sternum (sternocostal joints) are immediately caudal.
What is attached to manubrium?
[1] The sternocleidomastoid, sternohyoid and sternothyroid attach to the manubrium sterni. The transversus thoracis muscle attaches to the body of the sternum and xiphoid process. Pectoralis major is another major muscle attached to the body of the sternum.
What is manubrium of sternum?
Manubrium of sternum. Manubrium sterni. The manubrium is a large quadrangular shaped bone that lies above the body of the sternum. The lower border is narrower, is quite rough, and articulates with the body with a thin layer of cartilage in between.
Which part of the clavicle articulates with the manubrium quizlet?
The sternal end of the clavicle articulates with the manubrium of the sternum forming the sternoclavicular joint.
What is Manubrium of sternum?
Where is the manubrium of the 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.
What is the manubrium?
The manubrium is the thickest and strongest portion of the sternum and is therefore the area that is most likely to survive inhumation. It is broad and thick along its superior margin and narrows towards its inferior articulation with the mesosternum (Jit et al., 1980).
Which rib articulates with the manubrium only?
Ribs one and two articulate with the manubrium, but rib two articulates with only a partial facet of the manubrium at the sternal angle.
Which muscle originates on the manubrium of the sternum?
The sternocleidomastoid muscle is a two-headed neck muscle, which true to its name bears attachments to the manubrium of sternum (sterno-), the clavicle (-cleido-), and the mastoid process of the temporal bone (-mastoid).
What structure articulates with the clavicle 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.
Where does the manubrium articulate with the sternum?
On the lateral edges of the manubrium, there is a facet (cartilage lined depression in the bone), for articulation with the costal cartilage of the 1st rib, and a demifacet (half-facet) for articulation with part of the costal cartilage of the 2nd rib. Inferiorly, the manubrium articulates with the body of the sternum, forming the sternal angle.
What is the superior aspect of the manubrium?
The superior aspect of the manubrium is concave, producing a depression known as the jugular notch – this is visible underneath the skin. Either side of the jugular notch, there is a large fossa lined with cartilage. These fossae articulate with the medial ends of the clavicles, forming the sternoclavicular joints.
What is the superior aspect of the sternum?
The cartilage ossifies to bone during adulthood. The manubrium is the most superior portion of the sternum. It is trapezoid in shape. The superior aspect of the manubrium is concave, producing a depression known as the jugular notch – this is visible underneath the skin. Either side of the jugular notch, there is a large fossa lined with cartilage.
What do the clavicle and sternum articulate with?
It articulates with: 1 Both clavicles in their sternal ends. 2 Both ribs of the first pair. 3 Both ribs of the second pair (altough they also articulate with the body of the sternum) 4 The body of the sternum.
