The human life span is set in age stages; these are called Life Stages. The stages are listed from 0-3 years to 65+ years. Growth is a term used within describing the life stages because it’s a term to describe an increase in quantity. For example, as children grow the height and weight increases. We also use the term development; this describes the development of someone’s abilities, as they grow older. We can also use this term to describe the development of quantity change, such as height and weight. Also describing the lift stages, we use the term called maturation. This is different to development and growth. Puberty is an example of maturation because when development is expected to be due to a genetically automated sequence of change. Development norms, is another term we use to describe a set of average expectations to an infants or child’s development. Holistic development is similar but instead its describing someone’s physical, emotional, intellectual and social development in one.
Conception & pregnancy
A human baby’s life begins at conception. A woman usually develops 1 egg per month, roughly this happens 2 weeks after her last period. A women is most likely to get pregnant within a day or so of ovulation. An egg lives for about 12-24 hours after its released. For a woman to actually get pregnant the egg needs to be fertilized by a sperm cell within this time.
Pregnancy is divided into 3 trimesters. Each trimester is a little longer than 13 weeks. The first month marks the beginning of the first trimester.
1, 2 and 3 weeks
The egg is fertilized in one of the fallopian tubes and is carried into the uterus. Fertilization of the egg happens in the fallopian tube. As the egg passes through the fallopian tube is sets itself in the wall of the uterus. The embryo becomes a shape of a pear with a head shaped rounded, pointed lower spine and notochord running along its back.
4- 5 weeks
The embryo becomes C-shaped and a tail is visible. The umbilical cord forms and the forebrain enlarge; at this stage of pregnancy the internal organs a begun to form. During this stage of development, the embryo is vulnerable to harmful substances consumed by the mother, which may cause defects.
The eyes, mouth, nose and ears have begun to form and the limbs grow rapidly from tiny buds. The head and face has formed more human, the head is more upright, and the tail has gone. Legs and arms have developed. Fingers and toes have formed.
* The embryo develops into a fetus after 10 weeks.
* Fingers and toes are longer.
The umbilical cord connects the abdomen of the fetus to the placenta. The placenta is attached to the wall of the uterus. It absorbs nutrients from the woman’s bloodstream. The cord carries nutrients and oxygen to the fetus and takes wastes away from the fetus.
The fetus is now measured from the top of its head to its buttocks. This is called crown-rump length. The fetus has a CRL of 2–3 inches. Its Fingers and toes are no longer webbed whilst the Bones begin hardening. Skin and fingernails begin to grow. Changes triggered by hormones begin to make external sex organs appear — female or male. The fetus begins making spontaneous movements. Kidneys start making urine, Early sweat glands appear and Eyelids are fused together. 13-14 weeks (second trimester)
The baby has a CRL of about 3 inches long which is about 8 cm long at this stage. The sex of the fetus can sometimes be seen on the ultra sound of the mothers scan. Hair begins to grow on the babys head and the roof of the baby’s mouth is formed, whilst the prostate glands are developing on the male. Ovaries move down from the abdomen to the pelvic area in the female. 15-16 weeks
