Spinal nerve

through which neurons communicate. According to Carlson (2014) the Nervous system is branched into two categories - the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is made up of the brain and spinal cord. The PNS holds cranial nerves, spinal nerves and peripheral ganglia. According to Farley, Johnstone, Hendrey and McLafferty (2014), the brain is portioned into six different sections. These divisions consist of the medulla oblongata, pons, midbrain,…

and yet so dissimilar are Transverse myelitis and Optic neuritis. Both diseases are neurological and known to be connected to MS (multiple sclerosis). MS is a disease in which the nerves of your brain and spinal cord are inflamed and damaged. Optic neuritis is the inflammation of the optic nerve, which is the nerve that connects what a person to sees to their brain. Transverse myelitis is inflammation that can cause severe injury in…

signals between different parts of the body. It has two components; the central nervous system and the peripheral nervous system. The nervous system is an intricate part of your body and life that 's made up of two separate systems, the brain, and spinal cord. During prenatal growth, the nervous system experiences many changes to gain its compound structure. The events of this early development include the growing of billions of neurons, axons, and the formation of thousands of…

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 doe the term meninges mean? What are the 3 distinct layers of the meninges? Discuss this in detail. Meninges is membrane…

The spinal cord transmits information between the brain and the rest of the body. Injury to the spinal cord can cause paralysis and the inability to talk and permanent damage to the brain and legs . The spinal cord is made up of disks that protect nerves that run down the back. A spinal cord injury happens when one or more of the disks in the spine are broken or moved so that they are pinching the nerves. After you have surgery to move the bones off the nerve the problem is still not…

first 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…

myelopathy is a degenerative disease of cervical spinal. The onset is usually insidious, with long periods of fixed disability and episode of worsening of events are taking place. Concerning to the pathophysiology of cervical spondylotic myelopathy, the injuries which are frequently repeated to the spinal cord are caused by static mechanical factor, dynamic mechanical factor and spinal cord ischemia. These factors are responsible for affecting the spinal cord through direct or indirect trauma…

The second hypothesis regarding the Jendrassik maneuver’s role on the patellar reflex is that it allows people to calm their nerves, and not focus on what is occurring. People who are nervous tend to subconsciously keep their muscles tightened, and they also have high sympathetic tone present. When this occurs, the patellar reflex when activated will have a reduced response. However…

The nervous system is composed of two main parts which are the central nervous system and the peripheral nervous system. The central nervous system includes the brain and nerve cords like the spinal cord while the peripheral nervous system includes the motor nerves and sensory nerves. There are two main types of support cells in the nervous system which are glial cells and neurons. The neurons' function in the system is to receive and send electrical signals. The glial cells provide insulation…

About Having Spinal Fusion Surgery If you've had an injury to your spine that's made it unstable or fractured, it's probably giving you a lot of pain. The pain occurs because portions of your spine move independently of each other and they can pinch nerves and tissues when they are out of alignment. Your doctor may suggest a spinal fusion to correct the problem and decrease your pain. Here's a quick overview of this medical procedure. Fusing Your Spine With A Bone Graft A spinal fusion…
