- By Dr Ananya Mandal, MD. The human brain is divided into two hemispheres. The left hemisphere is the logical brain and is involved in language and analysis and the right hemisphere is the creative brain, involved in daydreaming and imagination. The left hemisphere controls the right side of the body while the right hemisphere controls the left side.

Definitions of Human Brain Components The vertebrate cerebrum (brain) is formed by two cerebral hemispheres that are separated by a groove, the medial longitudinal fissure. The brain can thus be described as being divided into left and right cerebral hemispheres.

Cerebral hemisphere in human nervous system: Cerebral hemispheres. Basic organizations of movement, such as reciprocal innervation, are organized at levels of the central nervous system lower than the cerebral hemispheres—at both the spinal and the brainstem level. Examples of brainstem reflexes are turning of the eyes and head toward a light or sound.

- Up till now, it is still a mystery as to who invented the wheel and when the wheel was invented. According to archaeologists, it was probably invented in around 8,000 B.C. in Asia. The oldest wheel known however, was discovered in Mesopotamia and probably dates back to 3,500 B.C. Fascinating facts about the invention of the Wheel by Mesopotamian's in c3500 BC. Based on diagrams on ancient clay tablets, the earliest known use of this essential invention was a potter’s wheel that was used at Ur in Mesopotamia (part of modern day Iraq} as early as 3500 BC.

Gross Anatomy of the Brain Use the models for the 3-D view. The cerebral hemispheres are made of gray matter and white matter. The gray matter is mainly neuron cell bodies and is found in two main places in the brain. The external gray matter is called the cerebral cortex, which is just below the pia. The deeper, internal gray matter masses are called nuclei.

cerebral cortex n a thin layer of gray matter on the surface of the cerebral hemisphere, folded into gyri with about two thirds of its area buried in fissures. It integrates higher mental functions, general movement, visceral functions, perception, and behavioral reactions.

They are like two mushroom caps bulging of the left and right front end of the brain stem, as shown in Figure 1 at the right. They control the activity of the lower levels, directing the overall plan and direction of behavior. Figure 2 at the left represents the left cerebral hemisphere in humans.

Cerebral cortex The cerebral cortex is the cerebrum 's (brain) outer layer of neural tissue in humans and other mammals. It is divided into two cortices, along the sagittal plane: the left and right cerebral hemispheres divided by the medial longitudinal fissure.he cerebral cortex is gray matter, consisting mainly of cell bodies (with astrocytes being the most abundant cell type in the cortex as well as the human brain as a whole) and capillaries.

brain The cerebral cortex is the largest part of the brain and is the area that is responsible for all our thinking activities. It is divided into two connected halves – the left and right cerebral hemispheres. The left hemisphere controls the right side of the body and the right hemisphere controls the left.or example, if a person sustains a brain injury, such as a stroke, to the left hemisphere in the area of the cerebral cortex that controls movement, this may result in weakness or even paralysis of the right arm and leg.

What is the cerebral hemisphere? A Answers (1) Follow Following Unfollow Pending Disabled. A Honor Society of Nursing (STTI) answered. The cerebral hemisphere is one half of the cerebrum, the part of the brain that controls muscle functions and also controls speech, thought, emotions, reading, writing, and learning. The right hemisphere controls the muscles on the left side of the body, and the left hemisphere controls the muscles on the right side of the body.

Cerebral cortex The cerebral cortex is the cerebrum 's (brain) outer layer of neural tissue in humans and other mammals.It is divided into two cortices, along the sagittal plane: the left and right cerebral hemispheres divided by the medial longitudinal fissure.n large mammals, the cerebral cortex is folded, giving a much greater surface area in the confined volume of the skull. A fold or ridge in the cortex is termed a gyrus (plural gyri) and a groove or fissure is termed a sulcus (plural sulci).

Division of Human Nervous System (with diagram) The Cerebral Lobes. Each cerebral hemisphere is divided into four lobes; the frontal, parietal, temporal, and the occipital. The Frontal Lobe is the most anterior lobe of the brain. Its posterior boundary is the fissure of Rolando, or central sulcus, which separates it from the parietal lobe. Inferiorly, it is divided from the temporal lobe by the fissure of Sylvius which is also called the lateral fissure.
