Post Retro #1: A story of a heart, snail and a carrot twin

Posted on 15 March 2009, old blog.

disclaimer: this is not a scientific article nor a medical note, it is merely the writers imagination when he looked at his notes while studying during a major sleepy phase. so he tries to scribble anything that could go out about this particular subject;
embryology-featal heart development.


the story starts when a snail named alb (not the real name) discovers that he has a special gift, he could bend his body parts and do some incredible acrobatic stunts!

he realises his ability since he was 23 days old!
but as he goes older, his body shape became fixed,
first was his head and bottom,
it became shaped like a snail head but with legs,
his friends always tease him as he look weird,
they called him 'cephalic head!cephalic head!'
'caudal tail!caudal tail!'

so days passed, alb became lonely, but as days goes by, he accidently developed many other depressions on his body, and because he doesent have any friends, his body parts was his only friends, so he named them all, the upper part which is nearest to his head was named trunchus arteriosus, next was bulbus cordis, then primitive ventricle and his twin, atrium and lastly sinus venosus.

as alb became happy with his imaginary friends, he started to do many incredible acrobatic stunts, he first start to make a u-shape with his body, then a s-shape, and by time, he was stuck because as he grows older, his shape became fixed!

alb was not happy because his friends was stuck with him too, so he wished that his friends will develop into a new life form so that he could play together again.

first was sinus venosus which transformed into an octopus!
he develops three important tentacles which alb named them with vitelline vein, umbilical vein and common cardinal vein. unfortunately because of his appetite for liver that he likes to eat with his right horn, his right became larger than the left.

then was the twins which develop into a carrot!
as they grew older, they became obsessed with body accessories, first they wore a pair of earrings named ventral and dorsal, then they decided to wear a chocolate tiara!(septum premium) which eventually closes his forhead (foramen premium) when it melted. so they decided to wear another one, a crest shaped tiara (septum secundum).

seeing his twin atrium trying to be beautiful, ventricle became envious. so he put up some muscle to make sure he looks tough to pump all the chicks blood, so his muscular part grew larger, upwards while his membranous part become smooth, as he know girls like a guy with a smooth heart but rough on the surface (musculi pectinati, papilary muscle)

and so alb became intact with bulbus cordis and truncus arteriosus which put on a pair of paddings on their leg and wore a spiral bulbar ridges. then attach itself with the ventricle (aorta and pulmunary trunk)


well, i ran out of stupid ideas at the end..hehehe
overall, this was an analogy of how our heart develops when we were three weeks old after gestation. hope it somehow provide some help for those with the exams!
