Every four seconds someone is diagnosed with Alzheimer’s currently the disease affects over fourty million people worldwide. Dr Alois Alzheimer was a German psychiatrist who first described the symptoms of Alzheimer’s in 1901 when he noticed a particular hospital patient had peculiar problems which were a difficulty in sleeping‚ disturbed memories‚ drastic changes to mood throughout the day and general confusion. When the patient passed away Dr Alzheimer was able to conduct an autopsy on the body

Disorders of the Nervous System The way we think‚ our emotions‚ and the ability of our body to tell itself to move all connect back to the nervous system. If one part is not connected to another or if something never developed properly it can create a major problem. Disorders can occur within the brain or can be malfunctions of the nerves. Disorders can range from Palsy and Parkinson’s in which symptoms are movements such as tremors to Alzheimer’s which is mental deterioration and loss of memory

Twin-Pulse Facilitation Measured as Twitch Ratios at the! Frog Nerve/Gastrocnemius Preparation ! Richard S. Manalis and Jonathan L. Miller— Department of Biology‚ Goshen College‚ Goshen‚ Indiana Introduction! Learning & Memory are related to synaptic efficacy which the present study brings to the undergraduate physiology laboratory. TWIN-PULSE FACILITATION has been widely used to study one aspect of short-term synaptic plasticity at a wide variety of synapses using electrophysiological methods

1. Which of the following is NOT true regarding the EPP? A. The EPP is a graded potential needed to reach threshold B. The EPP is the direct result of voltage-gated Na+ channels opening C. The EPP occurs in the post-synaptic membrane and is not an action potential D. To generate an EPP‚ ACh acts as the neurotransmitter involved in skeletal muscle contraction E. Two of the choices above are NOT true. 2. A person is being treated at a local clinic with an acetyl cholinesterase

Introduction: The overall nervous system is made up of the Central Nervous System and the Peripheral Nervous System‚ with the autonomic nervous system being a division of the peripheral nervous system. The autonomic nervous system regulates glands as well as the smooth and cardiac muscle. There are three separate systems within the autonomic nervous system and are called the sympathetic nervous system‚ parasympathetic nervous system and the enteric nervous system. They are responsible for the ‘fight

An Investigation To See The Effect That Alcohol Has Upon The Heart Rate Of Daphnia. Aim: In this investigation I am going to see how alcohol affects the heart. Due to the ethical and safety issues involved in using in an investigation such as this I am going to use Daphnia (water flea) to conduct this experiment. Although humans and Daphnia are very different organisms‚ the affect that alcohol has upon the heart should be similar. Hypothesis: The hypothesis I am going to test during the

What is an electromyogram? An electromyogram (EMG) is a test that is used to record the electrical activity of muscles. When muscles are active‚ they produce an electrical current. This current is usually proportional to the level of the muscle activity. An EMG is also referred to as a myogram. EMGs can be used to detect abnormal electrical activity of muscle that can occur in many diseases and conditions‚ including muscular dystrophy‚ inflammation of muscles‚ pinched nerves‚ peripheral nerve damage
