Some of these are the structural proteins, enzymes, etc., which are part of the normal functional equipment of cells throughout the body and thus are in no sense specific to this particular organ.

Normal and Abnormal Embryo-Fetal Development in Mammals, and the morphological links that are established. We consider the function of these biochemical signals in facilitating the process of implantation and the support of the corpus luteum of pregnancy. We review in some detail the growth and development of the embryo, the genetic basis for sexual diff

As the fetus grows in size and the various body systems develop, so the ‘physiology’ of

It was not until the tenth century that the Italian anatomist, Fabricius ab Aquapen-dente, proposed that the chief agent in the initiation of parturition was the muscular action of the uterus. In 1882, Spiegelberg re-emphasized th

A few non-amniotes have developed analogous structures which serve similar functions to the extraembryonic membranes, and these offer further insights into the requirements for successful fetal development (Hagan, 1951; Woollacott and Zimmer, 1975; Amoroso ., 1979; Bone .
