Amyotrophic Lateral Sclerosis (Lou Gherig’s Disease) Amyotrophic Lateral Sclerosis is a deadly disease of the nervous system. Also known as Lou Gehrig’s disease‚ ALS at this time affects 25‚000 people in the U.S. today. One in 50‚000 people will be affected in any one year. The average age for diagnosis of ALS is between 30 and 70‚ although there have been cases of teenagers contracting it.The average life span after diagnosis are three to 10 years‚ although 20 percent of those affected will outlive

2.2 Electrical Communication Study Guide by Hisrich 2.2.a How does communication happen within the body? Electrical Signals Nervous System Chemical Signals Endocrine System The nervous system is made up of neurons. Neurons communicate just like people do‚ but they send messages using action potentials (electricity passing through their axons). Each neuron picks up signals at its dendrites‚ passes the signals down the axon‚ into the axon terminals‚ and into the synapses. The synapse

“How does the brain naturally control pain? And how can we target these systems with treatments?” How does the brain receive pain? The brain receives pain through nociceptive stimuli which activates pain receptors on neurons called nociceptors. Nociceptors can be placed into two categories: A-delta (Aδ) fibres and C-fibres. A-delta fibres are small‚ myelinated‚ neurons that transmit signals fast and mediate sharp pain. C-fibres are smaller unmyelinated neurons that slowly transmit signals. They

new field of science. It is divided into major schools of thought‚ since one paradigm cannot be supported across all fields. However‚ they can all agree that something biological is related to behavior whether it is genetics or a part of the nervous system. Major Schools of Thought in Psychology Over the years‚ psychology has been splintered into seven different schools‚ including schools that no longer exist. Each school focused on a different aspect of behavior and had different ways of testing

Guillain-Barre syndrome (GBS) is an autoimmune disorder of rapid-onset muscle weakness as a result of damage to the peripheral nervous system. The peripheral nervous system is the portion of the nervous system that is outside the brain and spinal cord. Autoimmune means an illness that occurs when the body tissues are attacked by its own immune system. In this case they begin attacking nerve cells which communicate with muscles. They attack the myelin sheaths surrounding the axons of the nerve cells

people with epilepsy loose control over their body through seizures? Well the answer lays in the mechanism of cell communication. Cells communicate in order to perform any activity or work in your system. When an epileptic seizure attack is performed Paracrine and Synaptic signaling in the nervous system in charge of cell communication isn’t working properly. To begin with Paracrine signaling works with a cell that secrets substances by vesicles‚ released to the extracellular fluid where substances
