Endocrine System disorder
Case: 15 year-old Zinga is brought to the ER by her mother. She is hyperventilating, vomiting and complaining of nausea. Her mother states that her daughter has not seemed like herself lately.
She is very thin (and recently has been losing weight) although her mother indicates she has been eating and drinking continuously.
Her urinary frequency has increased dramatically. She has even been having trouble with bed-wetting although this previously had not been a problem.
What disease do you suspect Zinga could be suffering from?
As a doctor laboratory tests would you perform to confirm your suspicions?
How can you explain Zinga’s nausea and hyperventilation?
How would you describe Zinga’s breath and urine? What would cause them to be this way?
What treatment would you recommend for Zinga?

52 year old male admitted 2 weeks ago. complained of
malaise and a cough. CT scan raised the possibility of a cerebellar
infarct on the left side.
precious history:
treated for hypertension.
precious admitted 7 years ago with angina.
elevated plasma cholesterol on admission.
smoker.
Lumbar puncture performed showed the presence of Haemophilus sp.
patient was treated with benzylpenicillin, he then became
hypertensive, which was attributed to septic shock. noted at this
stage that he had a primary infection of the right ear.
what was the cause of death?
what were the signs and symptoms?

Observing the effect of placing the patient on a ventilator. Mechanical Ventilation with PEEP=0.0.
What accounts for the different direction of the pleural pressure during inspiration while spontaneously breathing compared to during mechanical ventilation?
Under what circumstance is alveolar pressure equal to airway pressure?

Describe the digestion and absorption and vascular transport of a fat (triacylglycerol). Include/specify all relevant mechanical and chemical digestion mechanisms. Identify specific locations, mechanisms and processes – as well as accessory organ contributions. Explain how specific digestive tract structures and components of other systems play a role in digestion, absorption and transport of this nutrient.

Describe the composition of semen. Indicate the reproductive structures each component derives from, as well as the function(s) of each component. Indicate normal volume and numbers as appropriate. Also explain the autonomic regulation of male sexual response (erection and ejaculation).
In: Anatomy and Physiology
Describe the structure and functional properties of: i) the (renal) filtration membrane, and ii) the respiratory membrane. Indicate what forces are involved in driving exchange at these locations, describe and quantify these forces, and describe what is exchanged. Finally, explain clearly Goodpasture Syndrome and how/why it compromises normal function of these two important “membranes”.

1. Adaptation of Touch receptors: use a penny, with the examinee’s eyes closed, place it on their forearm, start timing and record when the examinee no longer feels the penny. Add a second penny to another location, repeat the timed test. For the third portion stack the 3 more pennies at the first location, and time the examinee until they no longer feel the pennies.
a. Why is the adaptation of the touch receptors particularly important while we wear clothes? If the answer is not immediately apparent, consider the opposite phenomenon: what would happen, in terms of sensory input, if these receptors did not exhibit adaptation?
b. Are these fast or slow adapting receptors, and identify the receptor?

You are developing a new drug to treat Major Depressive Disorder (MDD). You know that patients do not show clinical signs of improvement when they begin taking an SSRI. Your goal is to create a drug that will result in immediate improvement for patients, and can be used with SSRIs initially, and discontinued once the SSRI becomes fully effective. (10 points total)
a. Explain how SSRIs affect transmission at serotonin synapses, and why clinical effects are not seen immediately after a patient starts taking this medication. (6 pts)
b. What part of neuronal transmission would you target with your drug? Why would this alleviate the issue with SSRIs? (NOTE: Your answer should be logical and specific, and draw on what we have covered about communication between neurons this module/semester.) (4 pts)
In the first unit of this module, we discussed the neural basis for learning and memory. (10 points total)
a. What connection does the magnesium block on NMDA channels have to the principle of ‘threshold dependency’ for forming new memories? (3 pts)
b. List one similarity and one difference between the role of NMDA and AMPA channels in the process of LTP. (2 pts)
c. What role does calcium play in LTP? (1 pt)
d. Whereas LTP is an increase in the effectiveness of synapses, LTD is a process by which specific sets of synapses are selectively weakened. Calcium is involved in both LTP and LTD. Explain how different concentrations of calcium would lead to LTP vs. LTD. Be specific in your response, including the enzymes activated by calcium and the downstream changes to the number of receptors embedded in the postsynaptic membrane. (4 pts)
