Anatomical Landmarks of Note
The jugular notch (which is also called the suprasternal notch) is a major anatomical landmark that is really easy to palpate on yourself - run your fingers along your clavicles medially, towards your sternum, and notice a U-shaped depression of about 1cm in between the ends of the clavicles. This is the jugular notch of the manubrium. Approximately 2cm below this you should feel a raised horizontal ridge. This is the sternal symphysis. The sternal symphysis is the joint between the manubrium and sternal body. It is classified as a 'symphysis'. A symphysis joint is also called a secondary cartilaginous joint (read more about these in Section 1.5.).
