respiratory anatomy Flashcards
bones forming the boundary of the thoracic inlet
T1 vertebrae, manubrium, first rib
what structure closes off the thoracic outlet
diaphragm
bones froming the boundaries of the thoracic outlet
T12 vertebrae, tip of rib 12, tip of rib 11, costal margin (ribs 7-10), xiphoid process of the sternum
what kind of joint is found between the sternum and the manubrum
symphysis
which costal cartilage articulates with the jolt between the manubrium and the body of the sternum
cartilage of rib 2
how do the ribs articulate with the costal cartilages
cartilagenous immovable joints - synchrondosis
how do the costal cartilages articulate with the sternum
synovial joints
costotranverse joints for true and false ribs
true ribs have sup shapes joints to allow rib to pivot, false ribs have flat which only allow angled movement
true ribs have bucket handle movement, false ribs have caliper movement
where do the lungs and pleural space reach in the midaxillary line
pleural recess reaches rib 10, lung reaches rib 8
Where do the lungs and pleural space reach posteriorly
pleural space reaches rib 12, lung reaches rib 10
where do the crura attach to the vertebral column
left - L1-2
right - L2-3
what tranverses the diaphragm behind these crura
descending aorta
which structure pierces the middle of the diaphragm
oesophagus
why its the oesophagus passing through the diaphragmatic muscle advantageous
contraction of diaphragm increases abdominal pressure, would force food up from the stomach
oesophagus is constricted with each diaphragmatic contraction which prevents this
where does the IVC pass through the diaphragm
through the central tendon at T8
