Question

Which one of the options correctly matches the human tissues/organs with their embryonic germ layers of origin?
begin{tabular}{|c|c|} hline Tissues/organs & Embryonic germ layers
hline (P) liver & (I) ectoderm
(Q) cerebellum & (II) endoderm
(R) femur & (III) mesoderm
hline end{tabular}

• A. ( {P-II, Q-I, R-III} )
• B. ( {P-III, Q-I, R-II} )
• C. ( {P-I, Q-II, R-III} )
• D. ( {P-II, Q-III, R-I} )

Hint:

Embryonic germ layers play a fundamental role in the development of specific tissues and organs. Understanding their origins helps in studying developmental biology and congenital anomalies.

Answer 1

The Correct Option is A

The correct matching of human tissues/organs with their embryonic germ layers is as follows: - Liver (P): The liver originates from the endoderm, which gives rise to the digestive system and its associated glands. - Cerebellum (Q): The cerebellum originates from the ectoderm, specifically the neural ectoderm, which forms the central nervous system. - Femur (R): The femur, being a bone, originates from the mesoderm, which forms connective tissues, including bones and muscles. Thus, the correct matching is ( {P-II, Q-I, R-III} ), corresponding to option (A).
