Q

From the head of the rib we move lateral to the (body/neck) of the rib and the neck is the connection between the head and the shaft of the rib at the level of the ___ of the rib. The start of the shaft is the tubercle. The tubercle has some facets on it as well (articular part and nonarticular part). The (articular/non articular) part is a facet that attaches to the facet on the (spinous/transverse) process. So the tubercle becomes the junction between the neck or body (shaft) of the rib. The shaft projects laterally and then anteriorly and then inferiorly. So you’ll see a (incline/decline) as it goes around your trunk. Running along the entire length of the shaft is a groove on the inferior aspect of the shaft called the ___ groove and in this groove we are going to find ____ nerves and blood vessels.
