A tuning fork is placed against the forehead of a patient. The sound is loudest in the left ear. What can you determine about the patient’s hearing? What is happening in the left ear and the right ear? Begin your Internet search with the National Institute of Deafness and Other Communication Disorders website. Also, search for deafness, hearing, and cochlea.


Be detailed in your explanation and support your answer with facts from your textbook, research, and articles from scholarly journals. In addition, remember to add references in APA format to your posts to avoid plagiarism. Review of APA format:

Phenytoin (sodium channel blocker) and ethosuximide (calcium channel blocker) are anti-seizure drugs that stop seizures from happening. These drugs work by inhibiting electrical impulses (action potentials) from occurring.
Explain the importance of sodium and calcium channels on a neuron and the reasons why action potentials do not occur when these channels are inhibited. Be sure to include the phases of an action potential, the channels involved, and the importance of an action potential.

Weight Loss surgery is becoming more and more popular as a treatment method for dangerously obese individuals. Listed below are three examples of individuals who may be a candidate for bariatric surgery.

Would you recommend bariatric surgery to any of these individuals? Make sure you explain why you would or why you wouldn’t recommend surgery for each person.

Person 1: A 75-year-old male, 5’9”, 290 lbs. He has always carried extra weight throughout his life, but in recent years has gained significant amounts of weight. He is diabetic and has a family history of heart disease.


Person 2: A 16-year-old female, 5’3”, 250 lbs. Raised in a family with poor dietary habits, she has been overweight and obese her entire life. Despite many, many failed diet attempts, she continues to gain weight each year.


Person 3: A 45-year-old male, 6’ 1”, 325 lbs. He was a football player in college, but in the years since, all of the muscle mass he used to carry has turned into fat. He is still mobile but isn’t able to do the physical activities he wants to do.
