Solved in 3 steps
- Sodium is an incredibly important substance in our body. You may remember from module one that sodium ions play a crucial role in conducting nerve impulses during depolarization. You may also remember from biology 20 that sodium is involved in muscle contractions. Hyponatraemia has a condition where there is too little sodium in the body. This can result on difficulty processing thoughts nausea decreased ability to balance seizures in coma on the other hand an excessive amount of sodium or hyponatraemia in the body can also lead to many different neurological problems including seizures in coma. Katrina has an excessive amount of sodium ions in her blood plasma. This is occurring despite the fact that she has been watching her salt intake and ensuring that she's drinking enough fluid throughout the day. Katrina has an aldosterone imbalance. What does Catrinas hormone feedback loop look like? When constructing a feedback loop, clearly label the structures or glands involved in the…Sodium is an incredibly important substance in our body.

Katrina has an excessive amount of sodium ions in her blood plasma. This is occurring despite the fact that she had been watching her salt intake and ensuring that she's drinking enough fluid throughout the day. Which hormone imbalance is causing this problem for Katrina? Explain your reasoning hormone: ___________________ reason: ______________________Which of the following is false? Steroids do not require a G protein and second messenger. The average pH of blood is 7.4 Increased levels of AMP will cause an increase in enzyme activity A G protein links the first messenger with the second messenger.
- Benzodiazepines bind to GABAa receptors and increase the effects of GABA. Which effect would you predict to see after treatment with benzodiazepines? Increased influx of potassium flow. Increased G protein action. Increased influx of chloride. Increased influx of GABA.Licorice is used as a remedy in Chinese traditional medicine and also is a flavoring for candy. When licorice is eaten, one of its components triggers the formation of a compound that mimics aldosterone and binds to receptors for it. Based on this information, explain why people who have high blood pressure are advised to avoid eating much licorice.Which of the following best chracterizes a primary hyperaldosteronemic state? Answers to choose: A urine potassium of 35 mmol/d, A urine potassium of 21 mmol/d?, A spot urine test where the sodium levels are greater than potassium levels?, Have long half-lives?, Circulating blood catecholamines are 99% bound to albumin?, Mone of the above accurately describes catecholamines? no references, just homework.
- Autism is a condition that is generally characterized by difficulties in communicating, understanding abstract concepts, and forming relationships with other people. Recent studies show that children with autism tend to have low levels of oxytocin. Oxytocin nasal spray has been tried as a medical intervention. List two main functions of oxytocin in the body.Consider the effect of a twofold increase in the ECF concentration of Na+ or K+ ions. Which increase in ion concentration is the more deadly and why? Hint: Consider if the calculated decrease in or the increase in bring the resting membrane potential of the nerve or muscle cell closer to threshold potential? Why would this change in ion concentration stop the heart from beating?There is a toxin extracted from pufferfish called tetrodotoxin (TTX), which completely inhibits (blocks) voltage-gated sodium channels. In low doses it can cause a slight numbness (people eat contaminated pufferfish sometimes!), in high doses it is lethal. Why is this the case? It prevents glutamate uptake and reuptake, causing seizures in the brain Ob. It causes excess neuronal activity, leading to excitotoxicity and cell death It destroys myelin around axons, slowing action potential propagation It prevents action potentials from being initiated, stopping all synaptic transmission O 0 o o
- Your patient has a condition called hyporenin hypoaldosterone, which results in low levels of aldosterone. [Note: the NORMAL actions of aldosterone in the kidney is to excrete K+ and reabsorb Na+.] This condition results in excess K+ in the blood (lab results showed 7.5 mmol/L K+ in the blood) and low levels of Na+ in the blood (lab results showed 110 mmol/L Na+ in the blood). Answer the following questions. For the calculation, show your work. A. What is the medical term for high blood K+ levels? B. Calculate the Equilibrium Potential for K+ using the above lab value and a normal ICF K+ level of 145 mmol/L. C. What is the normal RMP for ventricular cardiac myocytes? E. What effect can this condition have on the heart?Ca++ is an extremely important ion in the body. Describe its functions or actions in the following organ systems: a) skeletomuscular system b) nervous system c) cardiovascular system d) endocrine systemdescribe a second-messenger system and discuss itsimportance in human physiology;
