keel

do you know what is keel?

yesterday in Dr. Hussein Khairy's class, there was dis picture on the white board n Dr. Hussein Khairy asked
"what is this?"

being so human-anatomy oriented...most of us answered
"urinary bladder!!" (i guess, at least i did tot it was a urinary bladder...haha)
"look carefully, it's a ship!" he answered

a ship? confused how's a ship is related to our discussion

"see! this is the paddle n here's water...what about this?" (refer to the arrow)
"aaaaa???" i never tot that thing has a name...hehe
"it's a keel!...and dis?" (the one beside the ship)

"erm???"
"a hernia! and this is the hernia invaginated inside if you dun wanna excised the sac...it's called keel operation. it looks the same like the keel of a ship ryte?
keel is not a person's name it's  a description."

juz felt wanna share this new info...all my life i've never known about "keel" ^_^
n surely it's an extraordinary way of explaining it to us

it got me thinkin of how very wide these surgeon's general knowledge were before...
relating a keel of the boat to a hernia operation

now am feeling like being a surgeon...hehe

let's be on even keel...duniawi n ukhrawi
