Ch. 10 Bony Thorax - Sternum and Ribs Workbook Flashcards
what 3 structures make up the bony thorax
- sternum
- thoracic vertebrae
- 12 pairs of ribs
term for the long, middle aspect of the sternum
body
the most distal aspect of the sternum does not ossify until a person is about how old
40
the total sternum length on an average adult is about how long
7” (18 cm)
the xiphoid process of the sternum is at what approximate level
T9-T10
the sternal angle is at what level
T4-T5
what is another name for the sternal angle
manubriosternal joint
what is the name of the joint that connects the upper limb to the bony thorax (only bony connection between the bony thorax and upper limb)
sternoclavicular joint
what is the name of the section of cartilage that connects the anterior end of the rib to the sternum
costocartilage
T/F - the 11th and 12th ribs are classified as false and floating ribs
true
the anterior aspect of the ribs is called what
sternal end
the posterior aspect of the ribs is called what
vertebral end
which aspect of the ribs articulates with the transverse process of the thoracic vertebrae
tubercle
what are the 3 structures found within the costal groove of each rib
artery, vein, nerve
which end of the ribs is most superior
vertebral end
approximately how much difference in height is there between these two ends of the ribs
3-5”
which ribs articulate with the upper lateral aspect of the manubrium of the sternum
first ribs
the bony thorax is wider at the lateral margins in which ribs
8th and 9th
how many posterior ribs are shown above the diaphragm
10
what type of movement is the first sternocostal
synarthrodial
what type of movement is the 1st-12th costovertebral joints
diarthrodial - plane (gliding)
what type of movement is the 1st-10th costochondral unions
synarthrodial
what type of movement is the 1st-10th costotransverse joints
diarthrodial - plane (gliding)
what type of movement is the 2nd-7th sternocostal joints
diarthrodial - plane (gliding)
what type of movement is the 6th-9th interchondral joints
diarthrodial - plane (gliding)
what type of movement is the 9th and 10th interchondral joints
fibrous - syndesmosis
what are the joints that have diarthrodial movements classified as
synovial
what is unique about the true ribs
they attach to the sternum by their own costocartilage
what is unique about the floating ribs
they have no costocartilage
how much rotation should be used for the oblique position of the sternum for a large, deep-chested patient
15 degrees
what is the recommended kVp range for the oblique position of the sternum
70-85 kVp
what is the advantage of performing an orthostatic technique of radiography of the sternum
blur out the ribs and lung markings
