renaissance dental takes place in the fallopian tube pull in the head of the sperm cell or the spermatozoon penetrates the much larger ripe egg renaissance dental.
shell or the mature ovum this forms a single cell the Fertile light they fertilized egg or zygote which contains pairs of chromosomes in
the zygote stage over here it’s a fertilized egg passes along the fallopian tube within to hours is it it has divided into two cells then hours later into four salves and so on this process is known as cleavage and that is common across many animals
no cleavage happens no walls but it’s a little different and each stage the resulting cells become smaller gradually approaching the normal body and cell size then we get to the roof that’s I could divide several times to form I saw it blackberry like
the cluster of to cells or the marula at around to days after fertilization the marula leaves the fallopian tube and enters the uterine cavity so we’re following actually so I started here in the fallopian tube and now on the rule is entering number four
getting over here to the blastocyst about six days after fertilization the cell cluster forms a hollow cavity and is known as a blastocysts it floats within the uterus for around hours before landing on the thick uterus lining which softens to aid implantation
which is burrowing of the plasticized into the endometrium the inner group of cells will become the embryo itself and then we have the embryonic disc within the inner cells mass and embryonic disc forms
this separates the cell clusters into the amniotic cavity which develops into a sac that will fill with fluid and fold around to cover the embryo and the yolk sac which helps to transport nutri
