What is the shortest stage of development?

The germinal stage of development is the first and shortest of the stages of the human lifespan. The main events in this stage of development are illustrated in the figure below and described in detail in the rest of this concept. The germinal stage lasts a total of eight to nine days.

What is the fastest period of development?

Infancy is the period of most rapid growth after birth. Growth is even faster during infancy that it is during puberty. By the end of the first year, the average baby is twice as long as it was at birth and three times as heavy.

Is the embryonic stage the shortest?

The pre-embryonic period, known as the germinal phase, is the first and shortest phase of embryonic development. It lasts from fertilization to the second week of the embryo's life. In this phase of embryo development, the zygote repeatedly self-replicates.

What are the 5 developmental stages?

The 5 Stages of Child Development are Newborn Development, Infant Development, Toddler Development, Preschooler Development, and School-Age Development.

What are the 3 periods of development?

8 Stages of Development by Erik Erikson

What are the 4 stages of development?

What are the development stages?

What are the 7 developmental stages?

How many stages of development are there?

There are three broad stages of development: early childhood, middle childhood, and adolescence. The definitions of these stages are organized around the primary tasks of development in each stage, though the boundaries of these stages are malleable.

What are the age periods of development?

Infancy and Toddlerhood (birth through two years) Early Childhood (3 to 5 years) Middle Childhood (6 to 11 years) Adolescence (12 years to adulthood)

Is the fetal stage the longest?

The last and the longest stage of prenatal development is called the fetal stage, and it lasts from the ninth week until birth. Now, these stages are calculated based on fertilization age, meaning how much time has passed since the last ovulation, when the fertilization of the oocyte by the sperm took place.

What develops first heart or brain?

Thus, the first organ system to develop is the heart, blood and circulatory system, so that nutrients and waste can be transported throughout the growing embryo.

How long is the germinal stage?

The germinal period (about 14 days in length) lasts from conception to implantation of the zygote (fertilized egg) in the lining of the uterus. During the first week after conception, the zygote divides and multiplies, going from a one-cell structure to two cells, then four cells, then eight cells, and so on.

Is infancy the fastest growth stage?

Infancy is the period of most rapid growth after birth. Growth during infancy is even faster than growth during puberty. By the end of the first year, the average baby is twice the length it was at birth and three times its birth weight. Infancy is also the period when most of the deciduous, or “baby,” teeth erupt.

In which stage the growth is slow?

Lag phase is initial phase of growth where growth rate is slow. In log phase or exponential phase growth rate is faster. Gradually growth slows down in stationary phase.

What is the first stage of human development?

Stage 1 — Infancy: Trust vs. Mistrust

In the first stage of human development, infants learn to trust based on how well their caregivers meet their basic needs and respond when they cry.

What are all the types of development?

All development requires approval, however as different developments have different levels of impacts, developments are grouped into 3 kinds. The 3 kinds of developments are: Complying; • Merit; and • Non-Complying. Each of the different kinds of development has a different assessment process.

What are the 9 stages of development?

What are the 8 stages of human development?

What are the 12 stages of human development?

The major stages of the human lifecycle include pregnancy, infancy, the toddler years, childhood, puberty, older adolescence, adulthood, middle age, and the senior years.

Which of the three stages is the longest?

Stage 1: Labor begins

It's usually the longest stage, and it's divided into three phases: early labor, active labor, and transition. Some highlights of stage 1 include: Dilation (opening) of your cervix to 10 centimeters. Thinning of your cervix (called effacement)

What is the zygote stage?

zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.

How long is the zygotic stage?

The prenatal development is sometimes separated into three developmental periods. The first period is referred to as the period of the zygote. This stage begins at conception and lasts until the zygote is implanted in the mother's uterus. It lasts for about 10-14 days.

Which organ is created first?

The first organ system to develop during organogenesis is the cardiovascular system. The heart has established its four chambers by four weeks of development, whereas week six involves cardiac outflow separation and descent of the heart (and lungs) into the thorax.

Which part of the human body Cannot heal itself?

Teeth are the ONLY body part that cannot repair themselves. Repairing means either regrowing what was lost or replacing it with scar tissue. Our teeth cannot do that.
