and communicable disease. Although approximately 90% of polio infections cause no symptoms at all‚ affected individuals can exhibit a range of symptoms if the virus enters the blood stream. In about 1% of cases‚ the virus enters the central nervous system‚ preferentially infecting and destroying motor neurons‚ leading to muscle weakness and acute flaccid paralysis. Different types of paralysis may occur‚ depending on the nerves involved. Spinal polio is the most common form‚ characterized by asymmetric

Brain Function Table Component Definition Role in Learning and Development Neurons A neuron is a cell in the brain or another part of the nervous system that transmits information to other cells. Neuron cells are the information processing components of the brain responsible for receiving and transmitting information. Each part of the neuron plays a role in the communication of information throughout the body. Neurotransmitters A neurotransmitter is a chemical substance through which

Study Multiple Sclerosis (MS) is a chronic autoimmune disease of the central nervous system which continues to be on the increase throughout the world. A horrible and unpredictable disorder that can vary in presence from benign to partial disability to completely catastrophic as transmission between the brain and other areas of the body becomes interrupted and confused. With the onset of MS‚ the body’s own auto-immune system attacks the protective layer of myelin surrounding the spinal cord. Over time

Lab AMU Multiple Sclerosis A disease that affects the central nervous system (CNS) is known as Multiple Sclerosis (MS) and affects over 2.5 million people worldwide. Around 400‚000 people who have the disease reside in the United States. Of that 400‚000 the ratio is roughly one woman to every seven men. Multiple Sclerosis is a disease where the individual’s immune system attacks the central nervous system. The immune system attacks and damages the myelin sheath which is a coating that is around

Some of those changes will be physical‚ there will be changes in the brain‚ nervous system‚ cognition‚ problem solving and judgment and they will have major milestones in social and emotional development. Physical Development On average children in early childhood with grow two to three inches in height and about five pounds in weight

retention. Caffeine has a positive effect on learning and memory because it improves short term memory and increases reaction times. The caffeine travels to the hippocampus‚ which is the memory center in the human brain‚ which then works with the nervous system to retain the information‚ even if it’s only for a little while. The hippocampus is located in the medial temporal lobe of the brain. Caffeine stimulates the production of adrenaline‚ which is a hormone found in the pituitary gland. The pituitary

striated. Furthermore‚ it has slight similarities to the smooth muscles‚ because its contractions are not under conscious control. On the other hand this type of muscle is highly specialised. It is under the control of the autonomic nervous system‚ however‚ even without nervous imput contractions can occur due to cells called pacemaker cells. Cardiac muscle is highly resistant to fatigue due to the presence of a large number of mitochondria‚ myoglobin and a good blood supply allowing continuous aerobic

Although the basic elements of behavior are indeed a very complicated system‚ one must identify the different elements and discuss how they unite to form a very distinctive and efficient system. The body’s nervous system and brain are the producers of the basic elements of behavior. The human body is a tremendous and intrinsic machine with many parts all functioning in unison. Robert S. Feldman (2009) states‚ “The nervous system is the pathway for the instructions that permit our bodies to carry

the brain. The auditory system controls how people physiological and behavioral react to sound. Sound moves from the inner ear to the auditory cortex directly. Then sound moves to the temporal lobes where it is consciously perceived. Depending on the type of music will determine the response. As said by Westman‚ “The arousal level of the central nervous system depends upon the intensity‚ complexity‚ variability‚ predictability and meaning of sound stimuli. The auditory system responds most to changes
