Question

Write about internal factors affecting human development.

Answer 1

Human development refers to a progressive series of changes that occur as a result of maturation and experience. It is affected by internal as well as external factors.

The internal factors that influence development are -

1. Heredity - Genetic endowment in the form of genes and chromosomes influence growth and development.
2. Maturation - The natural unfolding of genetic potential at the appropriate time influences phylogenetic functions like crawling, walking, etc.
3. Endocrine glands - Hormones secreted by endocrine glands such as the Pituitary gland, Thyroid, Adrenal glands, etc., are released directly into the bloodstream and play an important role in body metabolism, homeostasis, growth, and development. for e.g., under secretion of the growth hormone by the pituitary gland may result in dwarfism.
