The Human Brain Is The Most Complex Organ Of The Body

The human brain is the most complex organ in the body. It is continuously growing and surprising researchers. As the brain develops, researchers are able to identify each progressive â€Å"growth spurt† into phases of development. Each stage has different characteristics. For example, the prenatal stage deals with psychological disorders at birth, while the pre-school period is determined by traits of egocentric thinking and increased memory. This is only touching the surface of the brains development. Throughout this paper, we will explore each stage in depth and discover just how much the brain develops over a lifespan. The human brain is constantly growing and changing over an individual’s lifespan. To fully understand the brain, researchers must examine the life span’s phases and study each facet of cognitive development from each perspective of the human lifespan from birth to death. The first official stage of development is called the prenatal stage. Grow th and brain development all start at birth. The prenatal stage determines initial intelligence and presents any psychological disorders that may have already occurred. An infant is highly affected by the mother’s use of drugs and alcohol. The drug use can permanently damage the baby’s brain and cognitive ability. Mothers and care givers must take special care in order to insure the infant is healthy when finally born. When the infant is born its brain is about sixty percent the size of an adult’s brain (Feldman).Show MoreRelatedThe Evolution Of Stem Cells1484 Words   |  6 Pagescells are undifferentiated cells that have the potential to differentiate into specialized cells that make up various organs in our body. Intriguingly, if the stem cells are given the right conditions, they can divide, differentiate and self-organize to form an organ by itself. Organs formed in this manner are called organoids. Specifically, Organoids are structures resembling organs , generated from embryonic stem cells in a three-dimensional culture system similar to in vivo. However, these structuresRead MoreEssay on The Cerebrum; The Key Organ of Humans814 Words   |  4 Pageswith, the human brain is the most complex part of the human body. It has control to every organ because of a primary functional unit which is the neurons. The exterior part of the brain has specific functions to every organ in the human body. Therefore, the human brain is the most important organ in the human body. A person can be left brained or right brained according to how they act. The Cerebellum is the trilobed structure of the brain. The cerebellum helps provide smooth coordinated body movementRead MoreThe Most Complex Organ Of The Body1379 Words   |  6 PagesThe brain is the most complex organ in the body. The brain is made up of a complex network of billions of nerve cells called neurons, as well as other kinds of cells, all protected by the bones of the skull. Every human on Earth uses it every single day, even when you are sleeping the brain is not sleeping, but sending signals all over your body to keep you breathing and alive and allow you to dream. There are many discoveries about how the brain evolved from the cave men, but recently there haveRead MoreThe Comparison of Nervous Systems in Humans, Cnidarians, Flatworms, and Annelids1671 Words   |  7 PagesNervous Systems in Humans, Cnidarians, Flatworms, and Annelids The nervous system is one of the most important organ systems in the body. It is in charge of all of the things that happen within the body. Being responsible for receiving sensory input from internal and external stimuli, integrating and processing information, and generating output, it would be hard to survive without a nervous system; however, there are different types of nervous systems in various organisms. Humans, cnidarians, flatwormsRead MoreThe Human Body: One of the Most Complex Productions in the World1722 Words   |  7 PagesThe human body is, in its simplest observation, an extensively vast web of cells. The human body is one of the most complex productions in the world. Looking at just one part of the body such as the eye makes it apparent the complexity of the body’s makeup. The body is comprised of cells that come together to make tissues. These tissues fit together to make organs. The organs coexist to form organ systems. These organ system make up the enti re organism that is man. The Nervous System is the pivotalRead MoreCentral Nervous System1222 Words   |  5 Pagescomposed of the brain and spinal cord. Together with the peripheral nervous system (PNS), the other major portion of the nervous system, the CNS coordinates the bodys interaction with the environment. The CNS is contained within the dorsal cavity, with the brain in the cranial subcavity (the skull), and the spinal cord in the spinal cavity (within the vertebral column). Then human nervous system is the most complex object know to science, as it includes the intricate CNS and a brain with 10 billionRead MoreEssay on The Five Major Structure of the Brain865 Words   |  4 PagesFive Major Structures of the Human Brain University of Phoenix PSY 240 October 27, 2012 Olivia Fransis The human brain is nothing short of incredible. In a way it’s the world’s most powerful computer because it can process tasks at lightning speeds and simultaneously be in control of our reflexes and every other voluntary and involuntary functions. It is the most important and complex organ as well as our core for learning At the point of birth, the brain weighs an average of 350 toRead MoreEssay about the human brain537 Words   |  3 Pagesthe brain and their functions. Although the brain isn’t the largest organ of the human body it is the most complex and controlling organ. It is amazing how complicated the brain is. The brain controls every action within and out of your body. The brain has main areas that contain different areas that have specific functions. For instance the basal ganglia holds the lentiform and the caudate. The brain isn’t just â€Å"THE BRAIN† it is actually a group of many parts. They help to inform the brain on theRead More3D-Printing Case Study969 Words   |  4 Pageshowever, a new material is being used to create objects: cells are now being used 3D-Print organs to reduce the number of people on the waiting list for organ transplants and ultimately to reduce death. This may seem too good to be true but researchers have to handle the hype among the people and perform research in secrecy due to areas having laws prohibiting the use of 3D-Printers. The idea of 3D-Printing organs can solve multiple issues in the medical field. The rise of the study can provide multipleRead MoreThe Human Brain Is A Remarkable Organ1346 Words   |  6 PagesThe human brain is a remarkable organ. It is one of the most important organs in the human body. The brain is responsible for most of what makes who we are, how we think and how we feel. Different parts of the brain control different aspects of our behaviour. There is a strong link between biological activity and psychological events. In addition to the interplay of chemicals like neurotransmitters and hormones, a lot of this has to do with that localised parts of the brain have specific functions
