These eggs were smaller in size and egg shells were muddy in color. Gallus domesticus eggs were collected which were 2 days or lesser in age with the help of a villager. Commercially available eggs were purchased randomly as and when required. And other 30 were from Gallus domesticus collected from nearby village. Out of which 30 were commercially available in market. Whole mounting and staining have also been tried. We tried to find easily possible ways to hatch chick embryos by incubation in the departmental laboratory. We from Department of Anatomy Belagavi Institute of Medical Sciences, Belagavi, thought of facilitating observational learning in few aspects of early embryology within the limits of the departmental laboratory. Used as the only laboratory material in a brief course, they afford a basis for understanding the early differentiation of the organ systems and the fundamental processes of body formation common to all groups of vertebrates. The chick is one of the most satisfactory animals on which student laboratory work in embryology may be based.
96 HOUR CHICK EMBRYO SERIAL SECTION SERIES
The law of biogenesis or recapitalization is that, every living thing in its individual development passes through a series of constructive stages like those in the evolutionary development. The process by which a fish, an alligator, or a chick grows from a single fertilized egg cell to its fully elaborated adult structure is fundamentally the same as those involved in our own development. Especially in case of early embryology, models play an important role. Teaching and learning embryology happens with the help of models and specimens. Real structures are observed in Gross Anatomy, Osteology and Histology where learning would be enthusiastic.
Human Anatomy is a branch of basic sciences which deals with structures.
An early chick embryo as learning model for study of embryology.

Keywords: early embryology, chick embryo, Gallus domesticus eggs, whole mounting This bridges the gap of seeing what is not usually observed and strengthens educational embryology Observation of brain swellings, heart swelling optic vesicle, nasal pit, pharyngeal clefts, neural tube, somites and limb buds, vitelline vessels provide valuable learning experience by direct interaction with the real environment. Results: Successful hatching rates were more in favour of Gallus domesticus eggs compared to others Conclusion: This experiment guides the easiest and simplest possible ways to successfully establish the learning module for early embryology in departmental setup using Gallus domesticus eggs. Materials and methods: 30 commercially available chicken eggs and 30 Gallus domesticus eggs collected from nearby villages were hatched for embryos to whole mount, fix and stain. Aim: With the basic concept of’ontogeny repeats phylogeny’, for the enrichment of learning early embryology, chick embryos have been used. This type seems deficient in human embryology, that too in the early phases. In basic science Anatomy, visualization of real structures gives rich learning experience. Background: In medical education, learning happens by variety of perceptions.
