Earthworm Action Potential Conduction Velocity: The Effects of Various Salts and Neurotransmitters When it comes to performing action potential experiments within the lab, the giant nerve fibers of an earthworm are an important tool for success. They yield a high success rate when compared to other organisms (Kladt, Hanslik, & Heinzel, 2010), and provide a more ethical means of testing how various neurotransmitters affect action potentials, instead of direct use on humans for pharmaceutical…

Extra glucose is produced. Mental alertness increases and your pupils dilate. Adrenal glands release the hormone epinephrine into the bloodstream (Macaulay, 198). Adrenaline (epinephrine) increases the amount of sugar into your blood, increases your heart rate, and raises your blood pressure. After all of these changes have been made to your body, you are now ready to fight or flee. The prefrontal…

Background & Objectives: Arthropods have neurogenic hearts, which have pacemakers as part of the nervous system found outside the heart. Vertebrates and molluscs have myogenic hearts, where the pacemaker is composed of specialized cardiac muscle within the heart. Daphnia is unique as it is a cladoceran crustacean reported to have a myogenic heart. To test this, use drugs known to change heart rate in myogenic hearts and observe if they have the same influence on Daphnia. Methods: Used a…

Why couldn’t Dracula’s wife fall asleep? Because of his coffin. Does anybody here know why we sleep? The only commonality we can all agree on, is that getting enough sleep we feel like Sméagol and not getting enough sleep we feel and look like golem. Not getting enough sleep is known as sleep deprivation. Sleep deprivation is a medical term for a sufficient lack of restorative sleep over a cumulative period so as to cause physical or psychiatric symptoms and affect routine performances of tasks…

Adrenaline in the bloodstream achieves its effects on heart rate by stimulating the adrenergic receptors on cells throughout the heart tissue. Epinephrine 's binding to these receptors triggers a number of metabolic changes. High levels of epinephrine causes contraction of the smooth muscle that lines most arterioles. The way in which adrenaline acts on the sinoatrial node to accelerate the heart rate has hitherto been obscure. However, in various…

Epinephrine has its uses, but over time it seems associated with more problems than benefits. No example is clearer than the problems it causes with the heart and the cardiovascular system. With this as background, please research and explain the “beta-blockers”…

company has a monopoly on them and is unfairly controlling the price. The price of epipens has been raised over 400% in the past few years because Mylan’s one competitor had a recall due to possible errors in drug dosage. The drug used in epipens, epinephrine, is inexpensive and each epipen carries only a dollars worth. The injector itself is bought by Mylan from a manufacturer for only $34.50 per pen! This is a very unfair raise in price and something needs to be done. European governments…

A reaction in a person exposed to an allergen is known as anaphylaxis ("Anaphylaxis | Causes, Symptoms & Treatment | ACAAI Public Website," n.d.). There are two types of reactions a person experiencing anaphylaxis can have, uniphasic in which symptoms come quickly, get rapidly worse, but once treated symptoms go away and don't return. The other reaction type is called bi-phasic, where symptoms start and go away for a period of time, then return with increasing symptoms. The most common causes…

In this week’s lesson we were given the opportunity to learn about the aspects of psychological disorders. According to module 13.1, “a psychological disorder is a condition characterized by abnormal thoughts, feelings, and behaviors.” Anything could possibly classify as an “abnormal” thought, feelings, or behavior. If someone is acting out of the “norm” from their perspective society or culture, it could possibly classify as a disorder. One of the top psychological disorder in America today is…

Observing at Arkansas Children’s Hospital is a day that I will never forget. At Children’s I was placed in the Emergency Department where I got to see and encounter many different patients, including a home trachea patient with croup, patient with deep lacerations to the forehead, a downs patient with undiagnosed diabetes, etc. While in the emergency department I got to witness firsthand how the doctors, nurses, and respiratory therapist really work together, and that their primary focus is…
