Quran's scientific miracle in revealing,
"The sense of hearing develops before seeing, as well the heart is the
first organ to develop and function in the embryo"
By: Mohamad massarweh
It is He Who gave you hearing, sight
and hearts. How little you give thanks! [23:78]
Three weeks after fertilization, the
human embryo develops to a "gastrula" a sphere that contains three
stem cell layers (germ layers). The Germ layers are arranged one on the top of
the other. Ectoderm is most exterior layer to what will be the umbilical cord;
it differentiates to brain and nerves. During the third week "Otic placode",
a small nerval plate rises from the brain area for differentiating to the
auditory and ear nerves
By the end of the third and the
beginning of the fourth weeks, the Optic placode appears and starts
differentiating to the optical and eye nerves
In day 19, two tiny blood vessels
"Endocardial tubes" appear in the "Mesoderm", the middle
layer of the gastrula, the endocardial tubes grow in parallel until they meet
and coalesce to form the heart
In the fourth week, days 22-23 the
heart starts beating and pumping the blood, to be the first organ to function
in the embryo. Noteworthy, The Human embryo is the only creature among mammals
and vertebras who develops the sense of hearing before the vision
