The cerebrum is divided into two halves: the right and left hemispheres(Fig. 2). The left hemisphere controls the right half of the body, and the right hemisphere controls the left half. The two hemispheres are connected by a thick band of neural fibers known as the corpus callosum, consisting of about 200 million axons. The corpus callosum allows ...
Each cerebral hemisphere can be subdivided into four lobes, each associated with different functions. Figure 3.The cerebrum is divided into four lobes: frontal, parietal, occipital, and temporal.
The surface of the cerebrum is called the cerebral cortex and has a wrinkled appearance, consisting of bulges, also known as gyri, and deep furrows, known as sulci(Figure 8). A gyrus (plural: gyri) is the name given to the bumps and ridges on the cerebral cortex (the outermost layer of the brain). A sulcus (plural: sulci) is another name for a groo...
Within the brain, there are fluid-filled interconnected cavities called ventricles, which are extensions of the spinal cord. These are filled with a substance called cerebrospinal fluid, which is a clear and colorless liquid. The ventricles produce cerebrospinal fluid and transport and remove this fluid. The ventricles do not have a unique function...
Neurons are the nerve cellsof the central nervous system that transmit information through electrochemical signals throughout the body. Neurons contain a soma, a cell body from which the axon extends. Axons are nerve fibers that are the longest part of the neuron, which conduct electrical impulses away from the soma. There are dendrites at the end ...

Oct 4, 2019 · The rough endoplasmic reticulum (rough ER) is a part of the endomembrane system of the cell and a subset of the endoplasmic reticulum (ER). This organelle is primarily concerned with the synthesis, folding and modification of proteins, especially those that need to be delivered to different organelles within the cell, or secreted from the cell.
