Alpha motor neuron

sensory information to the cerebellum and to the thalamus. The pons regulates breathing through particular nuclei that regulate the breathing center of the medulla oblongata (New World Encylopedia, 2014). The cerebellum plays an important role in motor control. It may also be involved in some cognitive functions such as attention and language, and in regulating fear and pleasure…

Multiple sclerosis (MS) affects about 2.3 million people from around the world and women are affected by it by about two times more than men. For characteristics, MS has three different phenotypic subtypes; progressive relapsing MS, secondary progressive MS, and primary progressive MS. The causes of multiple sclerosis are uncertain, but it is considered an autoimmune disease. An autoimmune disease is where the immune system attacks its own tissue. MS is thought to be responsible for…

A Glial Cell is a non-neuronal cell that maintains homeostasis from myelin and it also provides support and it provides protection from neurons in the central nervous system. Glial cells also provide support and protection for neurons in the peripheral nervous system. Glial cells are known as being in large quantities in the central nervous system. Glial cells are very different form nerve cells. They differ in the way that they do not participate in synaptic interactions and electrical…

Researchers have discovered that Alzheimer's can be determined by genes. 1)Purpose. The hippocampus is known for its role as a brain's structure for memory. As cerebral cortex shrinks so does memory causing hippocampus, and other brain structures to decrease their performance. According to researchers there is a healthy RNA and an altered RNA. Seventy year olds were analyzed the greater the gene score, the better they could think and remember. Those who were diagnosed with Alzheimer's had an…

ganglia motor circuit. The motor circuit consists of sending output information to the cerebral cortex , pedunculopontine nucleus and the midbrain locomotor area. The direct pathway consists of the the substantia nigra via the nigrostriadal pathway sends dopamine cells that are excitatory to the globus pallidis internus . The globus pallidus is inhibited creating disinhibition of the thalamus and excitory neurons are sent to the motor cortex. The result is facilitation to the lower…

The Truth About ALS and CTE: Can They Be Stopped? Imagine being trapped inside your own body; powerless, unable to do anything on your own. Thinking about old memories and just wishing for the chance to relive those happy moments when you are capable of doing the simplest jobs on your own. That is exactly how a person feels when they have Amyotrophic Lateral Sclerosis or commonly known as Lou Gehrig's Disease. ALS is a fatal neurological disease that attacks the nerve cells, which control one's…

The second DNA sequence protein came out as alpha-synuclein which plays a role in Parkinson's disease. "Parkinson's disease is a progressive disorder of the nervous system that effects movement." (Mayo Clinic ) It effects the movement by making the body stiff or hard to move or to control. There are five different stages of Parkinson's disease. The first stage is the mildest form of Parkinson's disease, the symptoms are so minimal that they are often missed. Some of these symptoms in stage one…

to baseline by 24 h) after neuronal activation associated with pharmacologically-induced convulsive and sensory stimuli as well as behavioral tasks (Morgan et al., 1987; Saffen et al., 1988; Link et al., 1995; Lyford et al., 1995). IEG-expressing neurons are known to be distributed across a wide variety of brain regions (Rosen et al., 1998; Guzowski et al., 1999; Vann et al., 2000; Hall et al., 2001; Ramirez-Amaya et al., 2005).…

Multiple Sclerosis is a rare disease. It affects the brain and central nervous system at different locations where the severity of the disease in patients happens over few weeks and months. Worldwide 2.3 million people are being affected by multiple sclerosis1. MS, an auto immune disease2 , occurs by combination of factor’s come together contributing to its occurrence majorly genetic and environmental factors1. These include the virulent micro-organisms such as “ Epstein Barr virus” being the…

As this happens, it ultimately leads to the death of neurons, which is going to cause brain injury. The imbalance in ions has played a major role in how cellular damage takes place when it comes to TBI. When ion channel dysfunction happens, it can lead to cystic fibrosis, epilepsy and irregular heartbeats…
