Sternum morphology Flashcards
What vertebral levels correspond to the position of the manubrium sterni
T3-T4
What seperates the manubrium sterni and corpus sterni
the manubriosternal symphysis
what vertebral levels correspond to the position of the corpus sterni
T5-T9
how many sternabrae for the corpus sterni
4 sternabrae
what articular sites for the costal cartilage of ribs will be identified on the corpus sterni
costal notches 2-7
what feature of the corpus sterni is present in 4-7% of the population
sternal foramen
what causes the appearance of the sternal foramen
failure of the ossification centers of the sternum to fuse together normally
will the xiphoid process remain cartilage throughout life
no
