Spinal cord

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…

topic on Spinal muscular atrophy affects 1 in 6,000 to 1 in 10,000 people. In 1898, described for the first time the classic infantile form of SMA. In this essay I will be discussing spinal muscular atrophy and its characteristics. I will discuss signs and symptoms as 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…

Amyotrophic Lateral Sclerosis or ALS is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. The progressive degeneration of the motor neurons in ALS eventually leads to their death. When motor neurons die, the ability of the brain to initiate and control muscle movement is lost. With voluntary muscle action progressively affected, patients…

They make up the nerves, which is how the body functions. If the nerves are destroyed, then so is the body. The nerves are centered around the spine, so when someone has a spinal cord injury, that is how they become paralyzed. When someone hurts themselves, the wound heals. However, nerve cells do not heal the same way. There is a protein in the brain that helps to prevent nerve cells from dividing on their own. This protein…

information from the brain and spinal cord, while the efferent nerves have to do with the muscles in our body. It also contains two divisions called the central or peripheral nervous system. The central nervous system contains only the brain and the spinal cord while the peripheral nervous system connects both the brain and the spinal cord to other parts of the body. The peripheral also carries out information and brings in information from the brain and spinal cord. The peripheral is divided…

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…

The nervous system carries data to and from the brain and spinal cord to various bodily parts. There are three main functions of the nervous system, including sensory input, integration of data and motor output which occurs in the Brain and/or Spinal Cord. Sensory input is described as when the body gathers information of data, which correlates with the human senses such as touch, taste and sight. Integration of data occurs in the brain only once the brain has processed the information and is…

thoughts and actions from the brain and spinal cord to a body part(s).The nervous system is made up of two parts- the peripheral nervous system and the central nervous system. The peripheral nervous system is a system outside the brain and spinal cord and it connects the central nervous system to the rest of the body. The central nervous system controls the activities of the body, meaning that it makes all the decisions; this incorporates the brain and spinal cord. I found the peripheral…

of the ligament allows for the gel like substance or nucleus pulposus to exit the disc. Both conditions can create pressure on the corresponding spinal nerves or even on the spinal cord which leads to neurological symptoms such as pain, numbness, tingling, and weakness throughout the area serviced by the corresponding spinal nerve or area of the spinal cord”(Ashby). This can cause many problems for the patient's spine. Chiropractors can treat the symptoms by “ adjusting the corresponding…

What does the term neroglia mean? What are the 4 types of neuroglia cells in the CNS? Discuss this in detail. Neuroglia is a group of 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…
