well as some treatments for the disorder. Spinal muscular atrophy is a genetic disorder that affects the control of muscle movement. It is caused by a loss of specialized nerve cells, called motor neurons, in the spinal cord and the part of the brain that is connected to the spinal cord. The loss of motor neurons leads to weakness and wasting (atrophy) of muscles used for activities such as crawling and walking. It is a hereditary disease that causes weakness to the muscles of the arms and legs…

Part Two: Diagnosis and Treatment 7. What is myelin and how does it affect the transmission of nerve impulses? Identify the cells responsible for the formation of myelin. Covering some axons is a multilayered lipid and protein called myelin sheath, this helps to insulate the axon and speed up nerve impulses. (Tortora pg. 407) An axon that is surrounded by myelin sheath, whether in the central nervous system (CNS) or the peripheral nervous system (PNS), is said to be “myelinated”, while the bare…

to form a certain part of the body, ie. liver, skin, muscle, bone. Two types of stem cells are: somatic (adult) and embryonic. Somatic stem cells are found in various parts of the body for example, within bone marrow, skin, muscle and even in the blood. They developed to replace dying cells…

controlled by the central nervous system (CNS). The brain and the spinal cord are the main components of the central nervous system. The brain is divided into three portions: the hindbrain which houses units of the brain that controls heart and sleeping patterns, the midbrain which links the forebrain to the hindbrain and also controls the heart rate and sweating, and the forebrain which controls our voluntary movement. The spinal cord acts as an information path of the body. It conveys messages…

messages to the spinal cord and brain to and from all parts of the body. Main organs of the nervous system are Nervous Tissue, Brain, Spinal Cord, Nerves, Sense Organs, and the Cerebrospinal Fluid. The nervous tissue is the main tissue of the central and peripheral nervous system. This tissue conducts nerve impulses and is composed of neurons. The brain sends messages to the spinal cord the peripheral nerves all over the body that serve to control organs and muscles. The spinal cord is a long…

cells, in the nervous tissue that supports neurons that keeps the nervous system functioning and together. The 4 types of neuroglis cells of the CNS: (1.) Astrocytes are cells that support and structure cells that is a barrier for the brain through blood. (2.) Microglial cells are cells that remove dirt and attack microbes. (3.) Ependymal cells are cells that covers and lines the surfaces and cavities. (4.) Oligodendrocytes are cells that makes myelin that holds the nerve fibers in place. What…

Comparing with other disabilities, diseases, spinal cord injury is a critical disorder in worldwide. Physiology and anatomy The spinal cord(SC) is a grayish-white structure that begins superiorly at the foramen magnum in the skull, where it is continuous with the medulla obolongata of the brain. It terminates at the level of the lower border of the first lumbar vertebra. The spinal cord is located within the vertebral canal of the vertebral column, which is surrounded by three meninges: the…

Spina Bifida, a condition that is classified as a neural tube defect that affects about 1,500 babies are born with each year where the spinal column is not completely closed over the spinal cord. There are two types of Spina Bifida, one being very mild and one being very severe. Although this can be a tough disorder with possible physical and mental disabilities, with the correct treatment and follow through many people with some assistance cam live their lives fully. Spina Bifida can vary in…

outside the brain and spinal cord. Both systems are requiring in the body for different functions. The central nervous system consists of the nerves in brain and spinal cord. The brain is responsible for organize and coordinate the information. Consciously and unconsciously, the brain has many functions such as to think, feel and homeostasis regulation in the body. It receives sensory inputs from the spinal cord and transfer out as the motor outputs. The spinal cord…

During 1938 baseball season, a great and prominent baseball player named Lou Gehrig noticed his performance on and off the field was not what it was supposed to be. He found himself stumbling over curbs and when running bases, he was more tired than usual, and he was fumbling the ball. On June 19, 1939, he was diagnosed with amyotrophic lateral sclerosis (ALS) on his thirty-sixth birthday. In the same year, Lou Gehrig retired from baseball, still considering himself to be the luckiest man alive…
