known by upper and lower motor neuron degeneration. As the upper motor neurons deteriorate, the cells “suffer from a retrograde axonal loss with secondary myelin pallor and gliosis”. While these changes are more severe at the brainstem and upper spinal cord, they…
brain is the control focal point of the human body. The human brain stores data, corresponding that data with other data to offer the body some assistance with making selections and to have the body put the decisions into actions. The brain and spinal cord are created from the neural tube. The neural tube then extends causing the tube to then makes three locales called the primary brain vesicles: prosencephalon, mesencephalon, and the rhombencephalon. The prosencephalon and rhombencephalon split…
nervous system is defined as the network of nerve cells and fibers that transmits nerve impulses between parts of the body. Amyotrophic lateral sclerosis (AKA ALS) is a progressive disease that attack the nerve cells found within the brain and spinal cord. On average 15 people a day are diagnosed with ALS, and on average patients die two to five years after diagnoses or early symptoms appear. The ALS Foundation’s goal is to find a cure for the fatal disease and provide relief to patients…
environment. Neurons are known as the messengers of the body. They are the nerve cells that send messages through the nervous system, while the nerve impulses send coded electrical signals from the neuron. The motor neurons carry the brain and spinal cord impulses, to the muscles and the glands, while the sensory…
ventricles, the 3rd and 4th ventricles, the cerebral aqueduct, and the central canal. Describe the purpose of the ventricular system. In your answer be certain to define components of this system that are more difficult the diagram; specifically Cerebral Spinal Fluid and Arachnoid granulations. (10 points) The ventricular system is made up of ventricles in the brain which contain CSF (Cerebrospinal fluid). The purpose of the ventricular system is to make and transport the CSF (Cerebrospinal…
Lou Gehrig’s disease is also known as Amyotrophic Lateral Sclerosis (ALS). ALS is a disease that affects the nerve cells in the brain and the spinal cord. It is a progressive neurodegenerative disease, this eventually leads to death. The patients lose the ability for the brain to control muscle movement. Since most motor neurons are lost, the patients may eventually become completely paralyzed. Motor neurons can no longer send signals or impulses to the muscle fiber resulting in no muscle…
a pathological process in which neurons are damaged or killed due to the excessive stimulation of certain neurotransmitters such as glutamate. This process of excitotoxic neuronal death is known to contribute to the pathogenesis of brain and/or spinal cord injury associated with multiple human diseases such as Amyotrophic lateral sclerosis (ALS). (2) ALS is a progressive neurodegenerative disease that involves both the upper and lower motor neurons. Glutamate excitotoxicity is one of three major…
Amyotrophic Lateral Sclerosis, more formally known as ALS or Lou Gehrig’s disease, is a neurodegenerative disease, causing the selective degeneration of both upper and lower motor neurons, as well as those in the motor cortex portion of the brain, which ultimately leads to the limited to complete loss of all voluntary muscle function. Now while the main pathology of ALS is the selective death of the previously mentioned motor neurons, more recent studies have suggested that the homeostatic…
could better the scientific understanding of SMA that could lead to a breakthrough in treatment that will strengthen infant’s bodies, extend life, and lead to a cure for their illness. Topic: Today, I am going to discuss a horrible disease, called Spinal Muscular Atrophy that plagues our children in the world today. Importance: This disease is the number one genetic cause of death in infants in America today. Credibility: I have been actively involved in fundraising money for research after…
The five main parts of the brain are:- Midbrain, Pons Varolii, Medulla Oblongata, Cerebrum and Cerebellum The midbrain is forms part of the brainstem (along with the medulla oblongata and pons varolii). It is responsible for your level of consciousness. The midbrain consists of two stalk-like bans that come out from the base of the cerebrum and lead into the pons varolii. It contains both grey and white matter. The pons varolii is located just below the midbrain and is responsible for…
