1. after fertilization to the birth. 4. Teleology:
1. Ligaments: fibers that connect different organs to each other inside the body such as bone to bone, bone to muscle, and bone to cartilage.
2. Phylogenetic: related to evolutionary development of individual organisms or organs inside the bodies.
3. Ontogenetic: the development procedure of an organism from initial steps after fertilization to the birth.
4. Teleology: explanation of the existence of a feature or organism based on their duty or the serving reason.
5. Marrow: Some fatty matters which are located inside the bone shafts and produce the blood cells.
6. Embryo: a non-formed off spring in the initial steps after fertilization. For example between week two to eight in human.
7. Callus: thicken skin which is usually made as a result of applied force and stress on the bottom surface of the foot.
8. Crouching: A body gesture in which the upper part of body bends to front and knees are bent.
9. Sole: the bottom surface of the human foot
10. Trait: a feature in the live organisms which distinguish that specific organisms from the others.
11. Heritable: Anything that can be transferred from mother or father to the child.
12. Gamete: A haploid (refer to the definition of haploid) cell which combine with another haploid with opposite sex and make a zygote (refer to the definition of zygote).
13. Preformationism: A hypothesis in the history of biology, in which people believed each live organism is made by development of a miniature version of the same organism.
14. Ovum: A female cell which can be divided after fertilization by a male cell and eventually causes growth in embryo.
15. Maternal and paternal: relating to mother, relating to father
16. Mitosis: The growth mechanism in tissue cells in which a cell divides to two cells with same chromosomes.
17. Zygote: a diploid (refer to the definition of diploid) cell which is made as a result of fertilization process between male and female cells.
18. Haploid: A cell which contains only half of the chromosomes.
19. Diploid: A cell which contains both sets of the chromosomes from mother and father.
20. Blastocyst: One of the early stages in the creation of mammals. It has an inner cell mass which later makes the embryo.
21. Uterus: a part of female body in which offspring is made and developed until the birth.
22. Cell proliferation: a procedure in which number of cells increase as a balance between cell division and cell differentiation.
23. Viscera: relatively large organs in human body especially in the abdomen.
24. Cardiovascular system: A system consisted of heart and vessels which is aimed to make the blood circulation in the body.
25. Lymphatic system: a part of immune system which is circulating a liquid called lymph in the body.
