I understand where the tissues and cells come from or develop. What I am having trouble with is the actual pathway they undergo in order to produce their products...
So, after much research this is what I got. Please someone just make sure it is right! Thank you!!!!

1.Skeletal Muscle = Fertlized Egg -> Inner Cell Mass -> Mesoderm -> paraxial mesoderm (somites) -> Schlerotome -> Skeletal muscle

2.Hepatocytes = Fertilized Egg -> Inner Cell Mass -> Endoderm -> Foregut -> hepatoblasts -> hepatocytes

3.Melanocytes = Fertilized Egg -> Inner Cell Mass -> Ectoderm -> melanoblasts-> Melanocytes

4.Pneumocytes = Fertilized Egg ->Inner Cell Mass -> Endoderm -> Foregut -> respiratory diverticulum -> Pneumocytes

5.Oocytes = Fertilized Egg -> Inner Cell Mass -> Endoderm -> yolk sac -> OOgonia -> OOcytes

6.Nephron = Fertilized Egg -> Inner Cell Mass -> Mesoderm -> Intermediate mesoderm -> metanephric mesoderm -> nephron

7.Epidermis = Fertilized Egg -> Inner Cell Mass -> Ectoderm -> Epidermis

8.Central Nervous System = Fertilized Egg -> Inner Cell Mass -> Ectoderm -> Neural plate -> Neural Tube -> Central Nervous System

And Guyz You are awsome!!!
