Genes are inherited by your parents which you have 23 chromosomes which become DNA. There are characteristics/traits that you get from your parents or their family. Genetic beginnings are important for teachers and other professionals to know because it can show someone’s personality and appearance. As well because each and everyone has their own unique self as they explained that the genes are called the blueprints of life, because they are the ones who are going to create in the future. 2. Describe the stages of prenatal development. Germinal stage-Fertilization for 2 weeks. The mother to become is fertilizing. The egg and sperm come together. Then Zygote which takes up to 266 days to become cells so it be born. The placenta is being formed to protect embryo. Sometimes …show more content…

For the reason, that at birth the baby’s brain is increasing about 25% and then when the bay is about 3 years old it has grown 75%. I think that the parts of the brains and the functions are important for the brain development. There are 6 parts. One is Frontal lobe which consists of emotions, word associations, problem solving, reasoning, memory habits, motor activities, and expressive language. Parietal lobe is manipulation of objects, location for visual attention, integration of different sense, and location for touch perception. Occipital lobe part is the vision. Cerebellum consist of balance and equilibrium, and some memory for reflex motor acts. Brain stem which regulates body functions, reflexes to seeing and hearing, controls autonomic nervous system, and affects level of alertness. Temporal lobe is hearing, speech, memory, and categorizing objects. Scientifically the fine and gross motor development is important which has to do with brain development. Some of those consist of holding finger, crawling, standing, and walking. It is important because they are capable of change when they are in those

Occipital Lobe - I chose not to include this part of the brain because you can live without it. The occipital lobe processes visual information from the eyes. This enables us to understand the information we are seeing. Even though it is great to be able to process the information, it is not required for survival.

Between conception and calving, there is a lot of behind the scenes work going on inside the uterus. Like humans, a bovine fetus undergoes distinct developmental milestones. Month 1 (9-10 millimetres) Day 0: the fetus is conceived either through the use of a bull or AI Day 19: the embryo attaches to the uterus Day 20-22: a heartbeat can be detected Day 25: limb buds begin to form and placentation starts Month 2 (5-8 centimetres) Day 30: udder tissue begins to form is the embryo is female Day 45: the testicles

When you are pregnant the first thing I learned was that the baby is called a zygote. Within the first week the zygote has grown to 100-150 cells. These first two weeks is called the germinal period. From a zygote you go to an embryo. It is an embryo from week 2 to week 8.

Prenatal Development: Conception through Five Months was written by Francis J. Beckwith. This article is about seeing if abortion is justified or unjustified by starting from conception to the sixth month of pregnancy. Francis says that pregnancy begins at conception. During the first month of pregnancy, the sperm and ovum connect, which is called a zygote. A zygote is a combination of DNA from both the mother and father.

The brain, in cahoots with the nervous and endocrine systems, controls our behavior, thoughts, and actions, involuntary and voluntary. Scientists have studied the brain and determined, to a reasonable extent, what regions of the brain control what skills. These studies of the brain have provided much valuable information about how injuries and any operations done to the brain can affect our behavior and ability to perform certain tasks. The brain is divided into 3 main areas, the forebrain, midbrain, and hindbrain. The hindbrain, located at the bottom of the brain, controls very simple basic functions of life.

framework. There are three primary areas of learning and development within the current early education framework, these include language and communication, physical development and personal social and emotional development. These are the most important areas on which observations and progress reports will be based from birth onwards, building these up will allow children to develop the skills for the secondary areas of learning: maths, literacy, understanding the world and expressive arts and design. Although the secondary areas of learning and development are officially tracked from age two, we can still make observations and track the development in these areas when children are younger • Communication and language: this area tracks children’s listening and attention, understanding and speaking. This area focuses on developing language experiences for children, creating opportunities for their skills to grow in a rich environment learning to speak and listen.

The brain is the most complex organ in our body. It serves as the command center of the human nervous system. The brain is composed of different parts and functions that are dependent upon each other. The brain consists of two distinct sides: the right and left cerebral hemispheres. The side of the brain that endures damage will impact the function on the opposite side of the body and impairs mental capabilities.

The human brain is the most complex organ in the human body. The brain itself as a whole is so fascinating. One part of the brain that intrigues me the most is the frontal lobe. The frontal lobe controls all of our voluntary movements as well as our personalities. The same lobe of your brain that controls your every movement such as waving your hand also controls your intelligence, your reasoning, and planning.

The cerebellum is often called, ‘little brain’. It is similar to the cerebrum is appearance and structure. However, the cerebellum is involved with regulation and coordination. Anatomy and physiology of the human and animals has always truly intrigued me particularly the encephalon, the brain.

These components are the foundations for the fetus when it comes to physical appearance, future characteristics they may possess, and the beginning stages to discover if baby will be healthy are maybe at risk. These risks include specific disorders that include Down syndrome, Sickle-cell anemia (a blood disorder), Tay-Sachs disease (a disorder that produces blindness), and Klinefelter’s syndrome (produces underdeveloped genitals, extreme height, and enlarge breasts). The stages of prenatal development are composed of stages that include germinal stage, embryonic stage, and the fetal stage. Parents that are expecting a child can expect some of the events that occurred during these three stages (Feldman,
