Begin by choosing one of the topics below, or propose a topic of your own interest from the assigned readings subject to instructor approval. Post your choice to the discussion board thread “Video Presentation Topics” as soon as you make your choice. You may not select a topic that has already been chosen by a classmate. The sooner you choose, the more options you will have.

    For this assignment, you will produce a 4–7 minute audio–video presentation on your chosen topic.

    Record, Upload, and Submit

    The Kaltura Desktop Recording tool is available for free to WCU students to assist with recording video assignments. Another software or tool may be used to record your assignment. Completed videos are required to be uploaded to your Kaltura My Media area before they can be submitted in the Blackboard assignment area via Mashups Tool > Kaltura Media.


    In your presentation, include the following:

    • Include at least one type of visual aid in your presentation such as PowerPoint slides, diagrams, white board use, etc.
    • You are expected to explain the processes or concepts in your own words using references to support your explanations. Include a reference list at the end and cite references verbally or with on screen citations.
    • Use appropriate master’s level terminology.
    • Include all necessary physiology and/or pathophysiology in your explanation.
    • Use detailed explanations to teach or explain. Your classmates and professional colleagues are your audience .
    • Reference a minimum of two sources; you may cite your etext as a source. Use APA format to style your visual aids and cite your sources. Include a reference page in your video.
    • Your presentation must include both audio and visual components and be professional in nature.

    Possible topics:

    • Explain endocrine feedback in terms of short, long, and ultra-short feedback loops

Manifestations Of Hypothyroidism and Hyperthyroidism


Institutional Affiliation

  • Introduction
  • Thyroid is a butterfly-shaped gland which is located in front of the neck.
  • It produces hormones which control the rate of metabolism in the body(Palace, 2017).
  • Thyroid can become overactive producing more hormones or under reactive producing less hormones. The respective conditions are known as hyperthyroidism and hypothyroidism.
  • These are two distinct conditions with different manifestations
  • Hyperthyroidism
  • Hyperthyroidism occurs when thyroid gland produces more hormone thyroxine than the body requires.
  • It causes acceleration of metabolism of the body which causes inadvertent loss of weight (Grais & Sowers, 2014).
  • Initially, most patients do not experience any symptoms, hence do not get diagnosed with hyperthyroidism until it is in its advanced stage.
  • Hyperthyroidism Manifestations
  • Irregular or rapid heartbeat and increased resting heart rate, which causes the palpitation of the heart.
  • Thin, delicate skin and irregular hair growth and fingernail (Daumerie & Fichter, 2017).
  • Pretibial myxdemia, which causes a thick redness on the front of legs, typically occurs with Graves’ disease.
  • Hyperthyroidism Manifestations cont..
  • Sweating, which upsurges due to augmented calorigenesis. It is often connected to heat intolerance
  • Menstrual disturbances in females such as decreased flow (Sindhu et al., 2016).
  • Pretibial myxdemia, which causes a thick redness on the front of legs and characteristically ensues with Graves’ disease
  • Enlargement of thyroid which causes a lump in the neck.
  • Hypothyroidism
  • Hypothyroidism, also known as underactive thyroid, is a condition where thyroid gland does not sufficiently produce certain important hormones.
  • Individuals with hypothyroidism condition will experience symptoms which are associated to a slow metabolism since the main function of thyroid hormone is to run the body’s metabolism (Palace, 2017).
  • Hypothyroidism Manifestations
  • Menstrual disturbances in females which is characterized by heavy flow.
  • Cold intolerance: individuals with Hypothyroidism condition cannot tolerate cold as other people around them.
  • Weight gain or increased difficulty losing weight as a result of low metabolism
  • In infants, it causes whitening the eyes and yellowing of the skin (jaundice) (Sindhu et al., 2016).
  • Depression
  • Elevated blood cholesterol level
  • Pain, stiffness or swelling in your joints
  • Causes slower heartbeat
  • conclusion
  • The thyroid can become overactive producing more hormones or under reactive producing less hormones. The conditions is known are known as hyperthyroidism and hypothyroidism respectively.
  • Individuals with hyperthyroidism experience symptoms which are associated to fast metabolism which sweating and enlargement of thyroid.
  • On the other hand, people with hypothyroidism condition will experience symptoms which are associated with slow metabolism.
