Six Primary Structures

The brain can be considered the most complex organ in the body and the centrepiece of the nervous system. Although the brain works as a unified whole, neuroscientists have identified areas within it that perform specific functions. This makes the brain interconnected by three different layers: the central core, the limbic system, and the cerebral cortex. All of which contain structures that regulate everyday life and psychological function.

What is the brain’s role in the learning process? Does the learning process include the three major areas of the brain: hindbrain, midbrain, and forebrain? The brain is one of the most captivating organs in the body. It plays a huge role in how we learn and is made up of many components. Neurons are brain cells and people are born with over a billion of them. Neurons discharge signals to transmit information throughout the brain; these signals are called synapses. Neurons produce dendrites and they get larger as we learn. However, a dendrite gets bigger only if there is existing knowledge on something already learned. The brain consists of three areas and four lobes. The three parts are known as the hindbrain, midbrain, and forebrain. The four lobes of the brain are the frontal, parietal, occipital, and the temporal.

The brain is the most important organ for regulating human behavior and thought. The brain is very complex and has taken centuries to discover how it functions. The brain is separated into four distinct regions or lobes. These regions are called the frontal lobe, the occipital lobe, the temporal lobe, and the parietal lobe. The frontal lobe is located directly behind the forehead and is the brain region that controls higher level thinking such as memory, planning, and judgment. The frontal lobe also contains motor cortex which allows voluntary movements. Another vital brain region is the occipital lobe. The occipital lobe can be found in the back of the brain. Its job is to process and store visual information. The occipital lobe

“It plays such a vital role in human life that many consider it the essence of life.”(Huffman 70) It contains the frontal lobes, parietal lobes, the occipital lobes and temporal lobes. The Frontal lobes receive signals from the other lobes such as motor control, speech production and other higher functions. The parietal lobes Receive signals for bodily sensations and interpret them. The occipital lobes are responsible for vision. The temporal lobes are responsible for hearing, language, memory and some emotion. All of these parts of the brain conduct essential bodily functions and need to be functioning properly like a

The cerebral cortex is the largest outer most part of the brain. It consist of tissue known as gray matter which is made of neuronal bodies. The optimal function of the cerebral cortex is vitally important. All information necessary to sustain life is stored and processed in the cerebral cortex. The tissue are divided into the left and right sides which are joined together by the corpus callosum. The cerebral cortex is divided into four lobes, the frontal, parietal, occipital, and temporal lobe. Each area carrying its own set of functions and responsibilities. These four lobes together make up the primary somatosensory area of the brain which controls the five sensory systems in the brain taste, olfaction, touch, hearing and vision. These systems receive sensory information from the thalamic nerve projections. The primary motor area of the brain consist of a much smaller area located within

The brain plays the most important role in assisting to achieve and complete these cognitive functions. Several structures compose the brain, and many have a key role in the completion of cognitive functionality. The

Within the two hemispheres are four lobes: the occipital lobes, pariental lobes, temporal lobes, and frontal lobes. The occipital lobes are responsible for visual processing including shapes, color, and motion. The pariental lobes, located in front of the occipital lobes, are involved in touch sensatino and monitoring the body's position. Located below the pariental lobes are the temporal lobes, which are involved with hearing and language. In the very front of the brain, behind the forehead, the frontal lobes are found. The frontal lobes are responsible for the coordination of movement and higher mental process such as planning, social skills,

The brain is the main asset of our body as it controls different functions, therefore it is part of the nervous system alongside the spinal cord. Our brain has four different parts (known as lobes) that are required for different types of bodily functions (found within the cerebral cortex). The different parts are called: -

1997). The cerebellum is connected by many multisynaptic pathways with all parts of the central nervous system, including the cerebrum, basal ganglia, diencephalon, limbic system, brainstem, and spinal cord. This makes the cerebellum one of the busiest connections in the human brain (Greg etal 1997).The largest portion of the brain is the cerebrum. This section contains tools which are responsible for most of the brain function, and it is divided into four subsections. The temporal lobe, the occipital lobe, parietal lobe, and frontal lobe. The cerebrum is divided into a right and left hemisphere which are connected by axons that relay messages from one to the other. This matter is made of nerve cells which carry signals between the organ and the nerve cells which run through the body. The parietal lobe is one of the four lobes located in the cerebral hemisphere, this lobe focuses on comprehension, visual functions, language, reading, and internal stimuli. Tactile sensation and sensory comprehension are the main trait focused in this lobe. The parietal lobe is separated into two different cortex’s named sensory cortex, and motor cortex, The sensory cortex which is located in the front portion of the parietal lobe receives information relayed from the spinal cord regarding the position of various body parts and how they are moving, this area of the brain can also be used to

The brain stem is something I find most interesting. The brainstem is the found in the lower extension of the brain, located in front of the cerebellum and intertwined to the spinal cords. It is made up of three structures. The midbrain, pons and the medulla oblongata. Its purpose is used as a stationary system, fowarding messages back and forth between numerous parts of the body and the cerebral. Multiple simple or complex functions that are vital for survival are you d within that region of the brain. The midbrain is a vital portion for ocular motion while the pons is connected with coordinating ocular and face movements, facial feelings, sound and balance. The medulla oblongata controls respiratory functions, blood pressure, heart beats and swallowing from the throat. Messages given from the cortex to the spinal cord and nerves that extend from the spinal cord are sent through the pons and as well as the brainstem. Probelms with these regions of the brain may cause brain damage. Without these functions, humans will not survive. The reticular activating system is located in

The human brain is one of the most amazing organs in a body and at the same time the most mysterious. It is the control center of the body and it’s important to understand the complexity of the human brain. Although your brain functions as a whole, it consists of three main parts, The Central Core, the Limbic System, and the Cerebral Cortex. Then those parts break into even smaller parts. The brain is just like the computer, it depends on certain parts to work correctly and get every day jobs and even more complex jobs done.

The prenatal period is the period between conception and birth. During this period it usually takes between 266 days to 288 days. Throughout the prenatal period the child is likely to grow around 20 inches and can weigh an average of seven pounds. Most importantly the prenatal period is divided into three different periods. The first period is the germinal period, which is the shortest period, lasting from conception to the end of the second week. Furthermore, the germinal period is very important, because in this period a linkage is created between the zygote and mother. More importantly, within a few hours after fertilization, mitosis occurs dividing the zygote into 32 different cells. After undergoing mitosis the zygote turns into a blastocyst containing 32 cells. The blastocyst will rapidly grow and will become surrounded with membranes that provide nourishment and protection. The cluster of cells that compose the blastocyst is the inner cell mass, which produces the embryo. The amnion membrane will actually enclose the embryo, while the chorion will form the trophoblast, which will form the placenta. At the very end of the germinal period the inner cell mass will separate into three different layers. The outermost layer is the ectoderm layer, which forms the nervous system. The middle layer, the mesoderm forms the skeletal, circulatory, and muscular systems. The innermost layer is the endoderm, which develops into the digestive tract. In the end the once

Separating the brain into the three main parts gives a much better idea as to how the brain functions. These three parts are the cerebral cortex, the brain stem and the cerebellum. The brain stem is the terminal from the brain to the body. This is where the brain will receive information from the

The brain is one of the most important organs of the body that coordinates all the activities. It is divided into three major parts namely: Cerebrum, Cerebellum, brain stem and diencephalon. Cerebrum is the largest part of the brain. It covers the diencephalon and is divided into right and left hemisphere longitudinally. Each hemisphere is subdivided into brain lobes, named as: Frontal lobe, Parietal lobe, Temporal lobe and Occipital lobe.

Frontal lobe is responsible for mental functions such as planning, language, and decision making. The temporal lobe is responsible in understanding language. The parietal lobe is responsible for our sense of touch, temperature and body position. The occipital lobe is responsible for vision.
