The stage of Muscles

The stage of Muscles

This stage is characterized with muscles encircling and tightly surrounding the bones. With the completion of clothing the bones with lahm (muscles and flesh), the human image starts to be more clear, as human parts are appropriately connected. After completion of myogenesis (muscle formation), the embryo can start to move.

This stage, which starts at the end of the 7th week (Figure 1) and ends at the end of the 8th week (Figure 2), is considered as the end of the stage of takhaloq (formation). Embryologists termed the end of the 8th week as the end of the embryology stage followed by the foetus stage which coincides with the Nash’ah (developing) stage as Quran stated. Allah says;

“And clothed the bones with flesh; then We developed out of it another creature. So blessed be Allah, the best to create.”
(Qur’an 23: 14)

Until very recently, embroylogists assumed that the bones and muscles in an embryo developed at the same time. For this reason, for a long time, some people claimed that thsee verses conflicted with science. Yet, advanced microscopic research conducted by virtue of new technological developments has revealed that the revelation of the Qur’an is word for word correct. These observations at the microscopic level showed that the development inside the mother’s womb takes place in just the way it is described in the verses. First, the cartilage tissue of the embroy ossifies. Then muscular cells that are selected from amongst the tissue around the bones come together and wrap around the bones.
