CSA 2 Exam

Question 1

Vertebral Landmarks

suprasternal (jugular) notch

sternal angle

xiphisternal joint

xiphoid process

Answer 1

suprasternal (jugular) notch = T3

sternal angle = T4/5

xiphisternal joint = T9

xiphoid process = T10

Question 2

Typoe of Joint

intervertebral joint

costovertebral joint

sternocostal joint

sternoclavicular joint

costochondral joint

interchondral joint

manubriosternal joint

xiphisternal joint

Answer 2

intervertebral joint = symphysis (2’ cartilaginous)

costovertebral joint = synovial plane

sternocostal joint = 1st is synchondrosis (1’ cartilaginous), 2-7 synovial plane

sternoclavicular joint = synovial saddle

costochondral joint = synchondrosis (1’ cartilaginous)

interchondral joint = synovial plane

manubriosternal joint = symphysis (2’ cartilaginous)

xiphisternal joint = synchondrosis (1’ cartilaginous)

Question 3

inspiration vs expiration

Answer 3

inspiration

diaphragm contracts, increase intrathoracic volume, decrease intrathoracic pressure, air drawn in

expiration

diaphragm relaxes, decreased intrathoracic volume, increased intrathoracic pressure, air expelled out
