#LAYERS OF THE BRAIN SKIN#

The graphic has three views: the cerebral cortex, the outer layer of the brain involved in a whole host of functions like sensory perception, motor control and learning the limbic system, a group of structures that deals with emotion and behavior and the neuron, the individual cells that transmit chemical messages throughout the nervous system. The cerebrum is made up of the right and left cerebral hemispheres. It maps out different regions of the brain like the frontal lobes or the neo cortex, what processes they deal with and how studies have shown that region to impact learning. Inside the cranium, the brain is surrounded by three layers of tissue called the. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement. Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. It includes two layers: The periosteal layer of the dura mater lines the inner dome of the skull (. The next layer of protection is the meninges which has three membranes that surround the brain and spinal cord to keep it from being. The brain has three main parts: the cerebrum, cerebellum and brainstem. The outermost layer, the dura mater, is thick and tough. It has multiple layers of protection starting with the first layer of protection being the skull or cranium, which acts as armor shielding the brain from blows.

Figure 5.1.1 Layers of Skin: The skin is composed of two main layers: the epidermis, made of closely packed epithelial cells, and the dermis, made of dense, irregular connective tissue that houses blood vessels, hair. Can you point out the small squiggle of gray matter that makes up the brainвЂ™s motor cortex? Or how about the eye fields, which control visual attention and eye movements? No? Take a look at this handy interactive infographic created by Open Colleges, an Australian online education company, which walks you through major parts of the brain and what they control. The brain is the best protected organ in the body. It also has numerous sensory, and autonomic and sympathetic nerve fibers ensuring communication to and from the brain.
