Ew - and duh

trixtahI just squicked myself by reading about the yolk sac a developing embryo has until about 7 weeks gestation (well, the sac remains until after birth, but the duct into what turns into the digestive area is occluded around 7 weeks and it becomes redundant).
Ok, of course I knew that mammals (and fish and birds and insects...) develop from eggs, but I had no idea that mammals produced yolk sacs during development as well. And I really have no idea why it squicks me, but it totally does. Gross.
You know, I wanted to become a doctor right from when I was about 7 till about 15 or so - I'm so glad I didn't. I put myself off in my teens by thinking about dealing with people vomiting and pus, neither of which are my favourite things - just imagine more of the fun I could have had in anatomy class, when reading about embryo yolk sacs and the like.
On another note, it must be said that London has a fantastic range of medically-themed museums and locations, ranging from the Chelsea Physic Garden through to the old St Thomas' operating theatre in the roof of a church. I meant to visit the Hunterian Museum last time I was over, but didn't get round to it. (I did manage to do 6 museums, 4 art galleries and Kew Gardens in England and Wales last year in a bit less than 2 weeks, so it wasn't too bad.) Maybe next year!
