Coloured SEM of an eight week old human foetus. The foetus’ eye, nose and hands are visible. The eighth week of pregnancy represents the end of the formative developmental stage, and the embryo becomes a foetus. It is human-like in appearance, with the head large in proportion to the body. All major organ systems are formed by the eighth week, but require much growth since the foetus is only about 3 centimetres in crown-rump length.

ReplyDeleteDanke anyways ;)
So you're an MD...
ReplyDeleteI really love your posts
ReplyDeleteWhy do we measure crown to rump for foetus only?
ReplyDeleteHonestly, it seems like a much more appropriate measurement for adults since we sit all day - cars, desks, restaurants, etc.
In light of this, i'd like to give my crown to rump measurement: 36 inches.
Please adjust your table heights accordingly to prevent my future posture and arthritis issues.
This is not something you see everyday
