Imagine waking up one morning and not remembering what happened the other day, or important things like the names of loved one? That is what it feels like to have a progressed stage of Alzheimer’s disease (AD). There are many known diseases in the world, but AD is a very deadly disease with no known treatment or exact cause. AD is a disease that more commonly develops in the elderly and not younger people. AD not only affects the patient, but it also affects their family and friends because they…

The aim of the experiment was to investigate the initiation of the peristalsis reflex in a piece of guinea pig ileum through the stimulation of the stretch receptors, and subsequently demonstrate that the peristalsis reflex is neuronal in origin and not just a property of the muscle itself. Several drugs including lignocaine, atropine, hexamethonium, and nicardipine were induced to a piece of guinea pig ileum under a standard hydrostatic pressure of 5.0 cm/H2O, and hence the effects determined…

The most widespread disabling neurological condition of young adults around the world is Multiple Sclerosis (MS). Sclerosis is a Greek word meaning hardening of tissue or scars. Another name for MS is Demyelinating Disease, 85% of people diagnosed with MS have Relapsing-Remitting MS (RRMS). Around 10% have Primary-Progressive MS (PPMS), there is also Secondary-Progressive MS (SPMS), and Progressive-Relapsing MS (PRMS). The least common type is PRMS. In MS your immune system mistakenly attacks…

More Money Should be Granted to Fund Research on the Alzheimer’s Disease Alzheimer’s Disease (AD) is a neurodegenerative disorder and the most common form of dementia that affects memory, thinking skills, behavior, and normal bodily functions. There are about 5.2 million Americans living with the Alzheimer’s disease in 2014. Currently there is no prevention, treatment, or cure for the Alzheimer’s disease. Every year more than 500,000 seniors die due to the disease. Alzheimer’s has a mortality…

signal is sent from the eye to the brain’s neurons. The neurons pass the signal down from one another through the different parts of the cells. The neuron sends the signal that the mother has disappeared from the soma down the axon. The axon then sends the impulse out the axon terminals through the synapses, the space between neurons. The impulse gets released as a chemical substance, called a neurotransmitter, through the synapse and the receiving neuron gets the signal through the dendrites.…

become more apparent with the help of a strong and productive nervous system; this would include any change in emotion, memory or the 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…

Signs and Symptoms Symptoms of hydrocephalus differ with age, disease development, and individual variations in acceptance to the illness. For instance, a child's capability to compensate for enlarged CSF pressure and extension of the ventricles varies from a grown-up's. The infant skull can enlarge to accommodate the buildup of CSF because the sutures (the fibrous joints that attach the bones of the skull) have not yet closed. In infancy, the clearest sign of hydrocephalus is frequently a fast…

Mitochondria, LHON The Organelle The most well known function of the mitochondria is to produce energy for the cell. It does this by regulating cell metabolism and respiration. Mitochondria carry out multiple other functions that are extremely important (such as various forms of signaling) The mitochondria also contains DNA which can have a direct effect on some functions of the human body if there is a mutation. ( Mitochondrion.(2016, October 9)) Word count 63 (not including headings or…

There are a few physical and mental changes which occur with aging. One of the most common physical change with aging is dealing with the skin. Often when people get older their skin becomes thinner and loses elasticity in the outer surfaces. Another physical change which occurs with aging is dealing with our bones and joints. Over the years our bones become more less dense and often results in a disease called osteoporosis. Osteoporosis can occur in both males and females also at any age. As we…

landing at its destination at the thalamus; thus, making it an ascending pathway. This pathway is further divided into three levels of neurons for transmission: The first level is where the sensation is translated into an electrical impulse from pseudounipolar neurons branching from the skin leading to the dorsal root ganglion where its axons synapses with the neuron at…
