Adolescence

This continues throughout life: through childhood and adolescence into adulthood.
Adolescence is a transitional stage of physical and psychological development that generally occurs during the period from puberty to legal adulthood (age of majority).

Human embryonic development

human embryoembryogenesishuman embryogenesis
Prenatal development starts with fertilization and the formation of the zygote, the first stage in embryogenesis which continues in fetal development until birth.
In biological terms, the development of the human body entails growth from a one-celled zygote to an adult human being.

Zygote

zygoticzygotesfertilized egg
Prenatal development starts with fertilization and the formation of the zygote, the first stage in embryogenesis which continues in fetal development until birth. The resulting zygote develops through mitosis and cell differentiation, and the resulting embryo then implants in the uterus, where the embryo continues development through a fetal stage until birth. In biological terms, human development entails growth from a one-celled zygote to an adult human being. Development before birth, or prenatal development is the process in which a zygote, and later an embryo and then a fetus develops during gestation. The chromosomes of the sperm combine with those of the egg to form a single cell, called a zygote, and the germinal stage of embryogenesis commences. The zygote contains a full complement of genetic material, with all the biological characteristics of a single human being, and develops into the embryo.

humanshuman beinghuman beings
In biological terms, human development entails growth from a one-celled zygote to an adult human being.
Human evolution is characterized by a number of morphological, developmental, physiological, and behavioral changes that have taken place since the split between the last common ancestor of humans and chimpanzees.

Human fertilization

fertilizationconceptionfertilisation
Prenatal development starts with fertilization and the formation of the zygote, the first stage in embryogenesis which continues in fetal development until birth. The process begins with fertilization, where an egg released from the ovary of a female is penetrated by a sperm cell from a male.

Early childhood

childEarlypre-school age
In developmental psychology, childhood is divided up into the developmental stages of toddlerhood (learning to walk), early childhood (play age), middle childhood (school age), and adolescence (puberty through post-puberty).
Early childhood is a stage in human development.

Preadolescence

Preadolescence, also known as pre-teen or tween, is a stage of human development following early childhood and preceding adolescence.

Child

childrenschoolchildrenkids
Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction.
Biologically, a child (plural children) is a human being between the stages of birth and puberty, or between the developmental period of infancy and puberty.

Hormone

hormoneshormonalprohormone
It is initiated by hormonal signals from the brain to the gonads: the ovaries in a girl, the testes in a boy.
Hormones serve to communicate between organs and tissues for physiological regulation and behavioral activities such as digestion, metabolism, respiration, tissue function, sensory perception, sleep, excretion, lactation, stress induction, growth and development, movement, reproduction, and mood manipulation.

Precocious puberty

early pubertyCentral precocious pubertyperipheral precocious puberty
Puberty which starts earlier than usual is known as precocious puberty, and puberty which starts later than usual is known as delayed puberty.
In most cases, the process is normal in every aspect except the unusually early age and simply represents a variation of normal development.

Auxology

Auxology, sometimes called auxanology (from Greek αὔξω, auxō, or αὐξάνω, auxanō, "grow"; and -λογία, -logia), is a meta-term covering the study of all aspects of human physical growth.
