Anatomy (Respiratory) Flashcards
What makes up the thoracic cage?
Sternum, 12 pairs of ribs, 12 thoracic vertebrae
Name A
Jugular notch of sternum
Name Joint B
Manubriosternal joint
Label C
Costal notches
Label Joint D
Xiphosternal joint of sternum
Where is the sternal angle
At the manubriosternal Joint on the sternum
What are the true ribs?
Ribs 1-7 are true ribs as their costal cartilages articulate directly with the sternum
What are false ribs?
Ribs 8-10 are false ribs as their costal cartilages do not directly articulate with the sternum
What are floating ribs?
Ribs 11-12 are floating as they do not connect to the sternum in any way
What is the costal angle?
The bending of ribs 3-9 are callled the constal angle
What are sternocostal joints?
1st-7th pairs of costal cartilages with sternum (synovial plane joints)
What are the interchondral joints?
Between costal cartilages 6-7,7-8 and 8-9 (synovial plane)
What type of joint is the sternoclavicular joint?
Synovial saddle joint
Where does the transversus thoracis attach?
The lower portion of the sternum to costal cartilages 2-6
