Question | Answer |
what are the structures that make up the bony thorax | sternum anteriorly,thoracic vertebrta posteriorly and 12 pairs of ribs |
what are the 3 divisions of the sternum | manubrium,body,xiphoid tip |
what is the other names of the manubrium | suprasternal notch,jugular notch,manubrial notch |
what is the other name of the body of the sternum | corpus,gladiolus |
what is the upper most border of the sternum called | manubrial notch,suprasternal notch |
what level is the upper most border of the manubrium | at the level of t2-t3 |
the lower end of the manubrium is the | sternal angle |
what level is the lower end of the manubrium/sternal angle is | t4-t5 |
the xiphoid tip is located at the level of | t9-t10 |
the inferior costal (rib)margin corresponds to the level of | L2-L3 |
what is the joint where each clavicle articulates with the manubrium | sternoclavicular joint |
what is the only connection between each shoulder girdle and the bony thorax | SC joint(sternoclavicular joint) |
what are the anterior ribs attach to the sternum by | costocartilage |
the clavicles and the cartilages of the first 7 pairs of ribs are connect how | directly to the sternum |
the costcartilage for the first rib attaches to the ------ | manubrium |
the costcartilage for the second rib attaches at the--- | sternal angle |
the 3rd-7th costcartilage attaches to------- | the body of the sternum |
8,9,and 10th also have costcartilage but attaches to ---- | the costcartilage of the 7th rib |
what are the first 7 pairs of ribs called | true ribs |
why are the first 7 pairs of ribs called true ribs | b/c the ribs are directly attach to the sternum by its own costocartilage |
what are the 8 through 12 ribs called | false ribs |
why are the 8th-12th ribs called false ribs | b/c they attach to the sternum indirectly |
what are the 11 and 12 ribs called | floating ribs |
why are the 11 and 12 ribs called floating ribs | b/c they do not possess costocartilage or connect anteriorly |
each rib has two ends called what | posterior or vertebral end or anterior or sternal end |
what is between the two ends called | the shaft or body of the rib |
the vertebral end has a | head and a flat neck |
lateral to the neck is a | tubercle |
the body extends------from the tubercle | laterally |
the posterior or vertebral end of the rib is how much higher than the anterior or sternal end | 3 to 5 inches higher |
inside the margin of each of each rib protects -------- | artery,nerve and vein. |
the inside margin is called the | costal groove |
where is the bony thorax the widest | at the 8th or 9th ribs |
what forms the costovertebral joint | head of the rib and the body of the thoracic vertebrae |
costotransverse joint is formed by the | tubercle of the rib and the transverse process of the thoracic vertebrae |
do the 11 and 12 ribs have costotransverse articulation | do not have a costotransverse articulation |
where is the costchondral union or junction located at | b/w the costocartilage and anterior or sternal end of the rib |
what is the classification of the costochondral union or joint | unique classification |
what is the movement of the costochondral union or junction | synarthrodial |
where is the sternocostal joint of the 1st rib located at | b/w the sternum and costocartilage |
what is the sternocostal joint of the 1st rib is classified as,and what mobility
(b/w the rib & sternum) | cartilaginous-no movement synarthrodial |
sternocostal joint of 2nd and thru 7th rib has what classification and mobility & movement(b/w the 2nd-7th ribs & sternum) | synovial joints,gliding motion,diarthodial |
interchondral joint b/w 6th thru 10th ribs are classified as | synovial joints,gliding motion & diarthodial |
the thoracic spine & sternum are superimposed in what position | AP & PA position |
the vertebral is much more-----than the sternum.so the body must be --------to visualize the sternum away from the vertebra & placed in the heart shadow for a more uniform density. | dense, rotated |
what can be done in place of a RAO,if the pt can't do that position | LPO |
why is a breathing technique used on a RAO sternum | to blur out lung markings over the sternum.this requires low kV65 low mA a long exposure3-4secs |
if a patient can't stand what can you do
(sternum) | cross table lateral |
