inferior surface
What makes up the posterior surface of the heart?
the left atrium
What are the major grooves of the heart?
coronary, anterior interventricular and posterior interventricular sulci
What is the crista terminalis?
- Is a smooth muscular ridge in the superior portion of the right atrium
- It divides the musculi pectinati and the right atrial appendage from the smooth surface of the
right atrium - provides anatomical separation the orifices of the IVC and the Coronary sinus
Where is the fossa Ovalis located?
The interatrial atrium (right atrium)
Where do the left and right kidney span?
Left: T12-L3
Right: L1-L4
What are contents of the renal sinus?
renal pelvis, renal arteries and nerves, major and minor calices
What vessels run alongside the abdominal part of the ureter?
gonadal arteries
The ureters open to the bladder where?
Trigone of Bladder
The kidneys are highly responsive to what?
Sympathetic Innervation
Where does the hepatopancreatic ampulla open into?
the descending limb of the duodenum

puborectalis, pubococcygeus, iliococcygeus
Anal canal doesn’t receive autonomic innervation from?
Celiac ganglion
what is the most likely diagnosis if a patient comes in with a runny nose and unable to smell?
Possible ethmoid fracture causing damage to the olfactory nerve resulting in anosmia
what is the most likely diagnosis if a patient comes in with a ear infection and inability to form facial expressions?
Facial nerve is being affected as it passes through the middle ear (facial canal) patient may have bell’s palsy (facial N. becomes inflamed due to viral infection)

Damage to sella turcia, resulting in lesions in the pituitary gland and damage to the optic chasim
Where does a spinal tap occur and why?
It is performed after L2, typically in between L3-L4
This is because the spinal cord ends at L2 so it prevents injury to the spinal cord

Right artery- right ventricle and atrium
- PDA
- Marginal artery
Left artery- left ventricle and atrium
- LDA
- circumflex artery
