Question
1. __________ is known as a __________, because it mobilizes glucose and other biomolecules to help control of stress.
4.aldosterone; glucocorticoid
2.A post-traumatic stress disorder patient will attempt to __________ ..
seek stressful situations
3. The __________ class of antidepressants appears to affect the activity of the biogenic amine neurotransmitters involved in depression; this class of drugs does not alter the amount.
MAO inhibitors
4.
An MAO inhibitor __________ acetylcholine.
5.
What happens to the resting membrane potential of -70 mV when channels, that permit both sodium and potassium to move through, open?
What happens to the resting membrane potential of -70 mV when channels, that permit both sodium and potassium to move through, open?
hyperpolarization
6.Once initiated, excitatory postsynaptic potentials last for hours, especially if a fast receptor is activated.
False
7.When one neuron has several axon collaterals that communicate with several other neurons, it is called divergence.
8.
Information on the amplitude of a particular response is coded for by the amplitude of the action potential generated.
9.
Action potential size cannot code for stimulus intensity. So, how can neurons code for stimulus intensity?
Opening of certain ion channels codes for different stimulus intensities. Some ion channels open when the stimulus is weak; different channels open when the stimulus is strong.
12.Which step of nerve or muscle firing would be directly affected by a change in extracellular K+ ?
Choose the best answer.

1.prolactin; glucocorticoid 2.aldosterone; mineralocorticoid 3.cortisol; glucocorticoid4.aldosterone; glucocorticoid

Answers:
1)Cortisol, is known as a glucocorticoid since it mobilizes glucose and other molecules to help control of stress.
Explanation:
Cortisol is known to be released in the body from the adrenal during stressful fight or flight situations. These situations require more energy so cortisol helps to elevate blood glucose levels for these stressful events and promotes gluconeogenesis as well. But prolonged high levels of glucose in the blood leads to increase the risk of developing insulin resistance and type 2 diabetes.
2) A post-traumatic stress disorder patient will attempt to?
Answer: A) Avoid stressful situations.
Explanation: Post-traumatic stress disorder or PTSD is a type of anxiety disorder which is experienced by people who have faced mental trauma in their life. It persists for a few days to weeks after the event.
It displays an array of emotions like fear, anger, restlessness etc. It is diagnosed if such disturbances continue appearing in an individual for over a month. Constant remembrance of the event even when one does not want to think about them, having nightmares are other symptoms. The people suffering from the disorder usually avoid any such kind of situations which could remind them of the situation they have been in.
3) The tricyclic class of antidepressants appears to affect the activity of biogenic neurotransmitters that cause depression and this class of drugs does not alter the amount.
