Limbs - Arms and Legs
The arms and legs (we call them "limbs") begin as small buds on the sides of the embryo body.
Human Limb Development during week 8
From week 5 to week 8 of development, changes occur in the shape and structure of the embryo limbs.
The arms begin to develop before the legs. If you look at the whole embryo the legs always look younger (less developed) than the arms (almost a stage behind, about 2 days difference).
Look above at the pictures and see what changes you can see in the shape, features and position of the arm and leg.
Towards the end of this time (9 weeks) the embryo will also begin to move the arms and legs.
Words Used
digit - word used to describe either the finger or toe.
limb - word used to describe either the arm or leg.
limb bud - the first time you can see on the embryo surface where the arm or leg will form. It looks like a "bud" or "paddle" without any features.
