human development stages

human development stages are the on going changes in which human undergo in their life span.whereby according to Gale Encyclopedia of Children's Health, 2006 Human development is the process of growth to maturity. The process begins with fertilisation, where an egg released from the ovary of a female is penetrated by sperm. The egg then lodges in the uterus, where an embryo and later fetus develop until birth. Growth and development occur after birth, and include both physical and psychological development, influenced by genetic, hormonal, environmental and other factors. Development and growth continue throughout life, through childhood, adolescence, and through adulthood to senility, and are referred to as the process of ageing.

There is no technique in the world that can give them what they are missing: life experience. Life experience takes time. As we go through life, if we are willing to take responsibility for ourselves and learn as much as we can along the way, we will develop maturity and character.

However, it is not a given. The passing of time does not necessarily lead to growth, but it is necessary to grow for those so inclined.

The reason why we need to understand the human developmental stages is to know what to do when.

When we have a broad understanding of human development, we know where we are in life. We know which goals are appropriate for which stage of development and which needs to satisfy. We also understand what not to worry about.

When communicating with people or helping others grow and develop, you can know which goals are realistic and appropriate for their level of growth and development. ~ inlpcenter.org

Stages of human development

1.prenatal development

is the process in which an embryo and later fetus develops during gestation. Prenatal development starts with fertilization, the first stage in embryogenesis which continues in fetal development until birth.

Infancy and childhood/Afterbirth

According to Macmillan Dictionary for Students Macmillan 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). Various childhood factors could affect a person's attitude formation

Puberty

According to Kail, RV; Cavanaugh JC (2010) On average, girls begin puberty around ages 10–11 and end puberty around 15–17; boys begin around ages 11–12 and end around 16–17
Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction. It is initiated by hormonal signals from the brain to the gonads: the ovaries in a girl, the testes in a boy. In response to the signals, the gonads produce hormones that stimulate libido and the growth, function, and transformation of the brain, bones, muscle, blood, skin, hair, breasts, and sex organs. Physical growth—height and weight—accelerates in the first half of puberty and is completed when an adult body has been developed. Until the maturation of their reproductive capabilities, the pre-pubertal physical differences between boys and girls are the external sex organs

Adulthood

Human adulthood encompasses psychological adult development. Definitions of adulthood are often inconsistent and contradictory; a person may be biologically an adult, and have adult behavior but still be treated as a child if they are under the legal age of majority. Conversely, one may legally be an adult but possess none of the maturity and responsibility that may define an adult.
