| Question | Answer |
|---|---|
| Q In which mediastinum is the Thymus found? Where does it lay in relation to the manubrium? | A In sup. just pos. to manubrium |
| Q The brachiocephalic vv. are formed by the internal jugular and subclavian. Which is longer? | A The L brachiocephalic v. |
| Q The brachiocephalic vv. are formed by the internal jugular and subclavian. Which passes in front of the scalene mm, and over the first rib? | A The R brachiocephalic v. |
| Q Q The brachiocephalic vv. are formed by the internal jugular and subclavian. Which brachiocephalic v. corsses ANT to branches of the aorta? | A The L |
| The SVC starts deep to #1 costal cartilage, and end where? | A It ends deep to #3 costal cartilage when it enters the RA |
| Q Which way does the aorta arch? | A the aorta arches posterosuperiorly and LEFT |
| Q The arch of the aorta starts on the R side at #2 costosternal joint. Where does it start it's descent? | A at the LEFT body of T4. Notice it switches sides as it arches. |
| Q There are two brachiocephalic VV., how many brachiocephalic AA. are there? | A just one-the "brachioc. Trunk". |
| Q The L common carotid, and L subclavian both branch directly off of the aorta. Where do the R sublcavian/common carotid branch off? | A The brachiocephalic trunk. |
| Q *** Is the L subclavian a. in front/behind the scalene mm.? What about the L subclavian v.? | A *** Artery is BEHIND the scalenes, and vein is in FRONT of them |
| Q Which of the R/L vagus nn. pass pos. to the root of the lung? | A BOTH |
| Q Does the R or L recurrent laryngeal (branch off vagus) ascend between the trachea and esophagus? | A the R |
| Q Does the R/L recurrent laryngeal n pass under the arch of the aorta? | A The L |
| Q The R vagus n. forms the pos. vagal trunk. What does the L vagus n. form? | A The ant. vagal trunk |
| Q What n. is found just lat. to the ligamentum arteriosum? | A The L vagus n. |
| Q The heart twists counter-clockwise as seen from the top. Which way do the nn. twist? | A Opposite, or clockwise |
| Q Do the phrenic nn. enter the thorax lat/med to the vagus n? Do they pass ant/pos to root of lung? | A Phrenic n. passes into thorax lat. to vagus, and passes ANT to root of lung. |
| Q How much of the phrenic n. supply is motor to the diaphragm? | A 2/3, so 1/3 is sensory |
| Q Is the trachea ant/pos to the esophagus? At what level does the trachea end? | A Ant, deviates slightly R, and end at the sternal angle, where it first divides |
| Q *** At what level does the esophagus peirce the diaphragm? | A *** T10, through the "esophageal hiatus" of R crus. |
| Q This is a flat, fibromuscular tube, that can't seem to run a straight course | A the esophagus, which is constantly getting pushed side to side by the aorta |
| Q The thoracic aorta is fron T4-12. Where is the aortic knob found? | A T4 |
| Q The thoracic lymphatic duct drains everything into the L. subclavian v., except.... | A head, neck, and R arm |
| Q What the thoracic lymphatic duct doesn't drain, the _______ takes care of? | A R. Lymphatic duct, into the R subclavian v. |
| Q The thoracic duct is the largest lymphatic channel, and is ant to T2-6. What is found to the R and L? | A The "cisterna chyli" on the R, and the subclavian v. on the L. Check the pictures on this one. |
| Q how many vv. are involved in the azygos system of vv.? | A 3. Azygos, hemiA, and accessory hemiA |
| Q The azygos v. runs from the pos. IVC to the SVC, but it can't be short. Where precisely does it extend? | A From the pos IVC in the abdomen, loops over the root of R lung, and into the SVC above the heart |
| Q At approx what level does the hemiA v. crossover to drain into the azygos v.? | A T9 The accessory hemiA v. also crosses over around this area, but this whole crossover thing tends to vary a LOT. |
| Q What drains intercostal vv. on the R side? | A Azygos v. |
| Q What drains the intercostal vv. on the L? | A T4-8 is accessory hemiA v. Below that is the hemiA, and T1-3 is actually the "sup intercostal v." |
| Q Large branches off of the symp ganglia form splanchnic nn. which go to abdominal viscera. What vert. levels for the Greater splanchnic? | A T5-9. lesser = T10-11, and least = T12 |
| Q Is the trachea attached to the esophagus? | A Yup. |
| Q What is another name for secondary bronchi? | A Lobar bronchi. Think: 3 lobes on R, 2 on L |
| Q secondary bronchi branch into tertiary, then into bronchopulmonary segments in each lung, then into bronchioles. What is another name for tertiary bronchi? | A segmental bronchi |
| Q You just swallowed me and i took a wrong turn into your bronchioles. Which do i hit first, terminal or respiratory bronchioles? | A terminal. This is the END of cartilage. |
| Q I just jumped down your throat and into your lungs, looking for alveoli. Where is the first place i find them? | A Respiratory bonchioles |
| Q *** The diaphragm is convex toward the thorax. Where does it attach circumferentially? | A ***lower 6 ribs, xiphoid, and vert up to L4. |
| Q*** Where does the diaphragm attach in it's middle? | A ***to the "central tendon", and forming a "trifoliate aponeurosis", w/ 3 leaves. Check your picture-it's not that scary. |
| Q *** The diaphragm has 3 parts to it's muscular portion. 2 slips go to the xiphoid (called sternal part) w/ spaces for nn. Where is the costal part? | A *** The costal part extends from the the inf 6 costal cartilages anteriorly w/ their ribs, forming the R/L domes. Check your plate, or pictures, or whatever. Put some clouds and stars around the diaphragm. |
| Q*** The costal part of the diaphragm extends from the ant. inf. costal cartilages w/ their ribs. Where does the lumbar part of the diaphragm extend? | A *** From 2 arches bilaterally, and 1 centrally, and the upper 3 or 4 vertebrae. No seriously, it's not that bad....check netters or grays. |
| Q In the lumbar part of the muscular portions of the diaphragm, 2 arches are formed bilaterally. We call the medial ones the medial arcuate ligament, and the lateral the lateral arcuate ligament. What mm. do these wrap over/around? | A The medial arcuate ligament passes around the psoas, and the lateral the quadratus lumborum. |
| Q What does "crura" mean? | A leg |
| Q ***There are various "apertures" or holes in the diaphragm for structures to pass through. Does the vena caval foramen get bigger/smaller on inspiration? | A ***The vena caval foramen is surrounded by tendons, so it gets BIGGER with inspiration. This is at the T8 level |
| Q ***There are various "apertures" or holes in the diaphragm for structures to pass through. Which hiatus is at the T10 level, and pinches on inspiration? | A ***The esophageal hiatus. It pinches b/c it is surrounded by mm. IT does this to help keep food down. |
| Q ***There are various "apertures" or holes in the diaphragm for structures to pass through. At what level is the aortic hiatus, and what happens to it w/ insp/expiration? | A *** T12 level, and there is NO respiratory effect |
| Q Aside from the vena caval foramen, the esophageal hiatus, and the aortic hiatus.....what hiatus am i forgetting? | A The sternocostal hiatus....if you want to NOT bother with one of these, this is the one. |
