Comparative Anatomy And Developmental Biology Of Vertebrates 

The students will :

CO 49: Comparatively analyze various biological systems of vertebrate groups (Pisces, Amphibia, Reptile, Aves,  Mammal)

CO 50: Appraise the development of integumentary and Skeletal systems in different classes of vertebrates.

CO 51: Differentiate the evolution of circulatory and respiratory systems and associated similarities and dissimilarities among vertebrates.

CO 52: Compare detailed anatomy of the brain and various sense organs in vertebrates and establish the evolutionary relationships among their development.

Approach in teaching:
