Development of The Human Body
The development of the human body is a complex structure of bones, muscles, nerves, blood vessels, and organs. Generally, the development of these body parts is called Human Development. Human growth begins at conception when an egg from the mother is fertilized by sperm from the father.
Development of the human body is the process of maturity growth. Although further growth and development of the human body continue after birth, this includes both physical and psychological development. And is influenced by genes, hormones, the environment, and other things. It develops throughout life from childhood and adolescence into adulthood.
The development of the human body from the embryo to a full-grown adult is a dynamic process that continues throughout a person’s lifetime. During Human Growth different phases come in which are controlled by different factors. Each phase differs from the other in some aspects but is linked to each other within a sequence of biological development.
The developing embryo is initially conceived as an identical twin. It begins with division into separate cells and progresses to multi-cellular differentiation to form parts of the body. The human development cycle is divided into three broad stages- pre-embryonic, embryonic, and fetal; each continuing for 9 months. The human development stages consist of fertilization, embryogenesis, gastrulation, neurogenesis, organogenesis.
