Question

identify the bone indicated by the arrow.
answers: a - d
a scapula
b xiphoid process
c manubrium
d sacrum

Explanation:

The manubrium is the superior part of the sternum. It has a somewhat quadrangular shape. The xiphoid process is the inferior - most part of the sternum (a small, cartilaginous part). The scapula is a shoulder bone (not part of the sternum). The sacrum is a part of the vertebral column. Based on the anatomical position and shape (as the upper part of the sternum - like structure in the image), we can identify it.

Answer:

C. Manubrium
