Fetus – Just a "Blob of Tissue"?

"I opened the sock up and I put it on the towel and there were parts in there of a person. I’d taken anatomy; I was a medical student. I knew what I was looking at. There was a little scapula and there was an arm, and I saw some ribs and a chest, and I saw a little tiny head, and I saw a piece of a leg, and I saw a tiny hand. ... I checked it out and there were two arms and two legs and one head, etc., and I turned and said, I guess you got it all ... It was pretty awful that first time... it was like somebody put a hot poker into me." (Dr. David Brewer, in training)
