blood-brain barrier A mechanism that prevents some substances in the blood from reaching the brain. It is achieved by brain capillaries, which unlike other capillaries elsewhere in the body, are composed of endothelial cells sealed together in continuous tight junctions and surrounded by astrocytes that contribute to the selective passage of substances. Lipid-soluble substances such as alcohol, caffeine, nicotine and most anaesthetics, as well as glucose, oxygen and water, pass rapidly into brain

The Brain Terrie Oliver Axia College of University of Phoenix The Brain The brain is part of the central nervous system, which is located in the skull, and a very complex organ, with massive information data that flows throughout the body. The brain is like a hard-drive: storing daily active, awareness, memory, emotions, and reason. The brain is where decision-making is done, right, or wrong, what could have been, or should have been. The brain with all its mysterious complexities

teeth like that of apes. They had the brain size of chimps, about 480 ml, and weighed about 105 pounds on average. They also had long and heavily muscled arms and relatively shorter legs. These early hominins looked like apes, except they walked bipedally. Microscopic analyses of their teeth indicate a mixed vegetable diet of fruits and leaves. The fossil skeleton of ‘Lucy’ is an example of Australopithecus. The adaptive themes of bipedalism, large brains, complex social organizations, and tool

central and peripheral nervous systems. While the CNS include the brain and the spinal cord the PNS are the sensory neurons and nerves that connect them together. The human central nervous system is made up of the spinal cord and brain. The nerve cells are working between the brain. The spinal cord acts as a signal between the brain and the rest of the body and it controls the musculoskeletal reflexes without help from the brain. The brains responsibility as it's connected to the CNS is to coordinate

Nervous System The nervous system is organized into two parts: the central nervous system, which consists of the brain and the spinal cord, and the peripheral nervous system, which connects the central nervous system to the rest of the body. In the central nervous system, the brain and spinal cord are the main centres where communication of nervous information occur. Both the brain and spinal cord are covered with a system of membranes, called meninges and are suspended in the cerebrospinal fluid;

Music is much more than idle entertainment. It affects the brain in physical ways, altering pathways and stimulating certain areas to grow. Listening to music provides a temporary rise in cognitive IQ levels and learning it actually changes those levels on a more permanent basis. Professional musicians especially show marked differences in physical brain structure and cognitive thought processes. In 1993, a study was done at the University of California, Irvine that showed a temporary improvement

will hear words and not understand, hear sounds around them and will not know what they are, until they are taught, they do not know at this time how important their senses will be to them later in life and how their senses will interact with their brain. Now as we grow into adults our senses have become interwoven with the way we think and use our minds. We use our eyes to read a book or even recipes to cook. When we listen to music, hear the birds chirp, our children laughing we are using
