Manubrium

The manubrium is the upper part of the sternum.
It measures approximately 2 inches in length.
It contains the suprasternal and clavicular notch.
It lies opposite the levels of the third and fourth thoracic vertebrae (T3 and T4).
It articulates with the body of the sternum at the manubriosternal joint.
It also articulates with the clavicles at the sternoclavicular joints.
The manubrium articulates with the first costal cartilage on each side.
The sternoclavicular joint is a synovial saddle joint.

Manubrium

The manubrium is the upper part of the sternum, measuring approximately 2 inches in length.
It features the suprasternal (jugular) notch and clavicular notches.
The manubrium lies opposite the levels of the third and fourth thoracic vertebrae (T3, T4).
It connects with the body of the sternum at the manubriosternal joint.
The manubrium also connects with the clavicle at the sternoclavicular joint on either side of the body.
The manubrium articulates with the first costal cartilage on each side.
The sternoclavicular joint is a synovial saddle joint.

This quiz covers the anatomy of the manubrium, the upper part of the sternum, including its measurements, articulations, and associated joints. Test your knowledge on its relationship with the thoracic vertebrae and the clavicles. Ideal for students studying human anatomy.
