An individual is admitted to a hospital rehab center for opioid dependence. They began therapy using Suboxone (partial agonist) at 50 mg/day. Each week, their dosage was reduced by 10 mg until they weaned off the medication. They were then released and sent home. Explain what happened physiologically during their treatment

Do you think a ligand can be both a paracrine and autocrine signal? Explain your reasoning

A 77-year-old woman was cooking in the kitchen when she collapsed onto the floor. Her daughter called an ambulance and the woman was taken to the emergency room. She had suffered a stroke, and slowly regained consciousness over the next two days. However, when she woke up, she had the following signs and symptoms:

• Compare the type of fibers that make up the dorsal root and ventral roots
• Describe the connective tissues of nerves

In normal condition during ventricular systole, the left ventricle is the first to begin contracting, but the right ventricle is the first to expel blood. How can you explain this difference? There are two different reasons! And in dilated cardiomyopathy of the left ventricle, the ventricle can become enormously enlarged. Explain why this might lead to regurgitation of blood through the mitral valve (blood flowing from the ventricle back into the left atrium) during ventricular systole.

What happens if you have an imbalance between osteoblasts and osteoclasts? Specifically, what happens when you have too many osteoblasts versus when you have too many osteoclasts?

Describe the membrane potential and explain how it is produced

predict what would happen if the tyrosines in the activation loop of insulin were mutated to phenylalanine

phenylalanines will likely be phosphorylated but insulin recptor will not be activated

phenyalanines cannot be phosphorylated and insulin would not be activated

phenylalanine will likely be phosphorylated and irs 1 will bind and be phosphorylated

phenylalanine cannot be phosphorylated but irs 1 will bind and be phosphorylated

Are excitatory graded potentials depolarizing or hyperpolarizing?

What is the name for graded potentials from different stimuli adding together?

Name what kind of ion channels are open and which direction the ion moves for each part of an action potential.

a. Depolarization Na channels open,

b. Repolarization Na channels open,

c. HyperpolarizationNa channels close,

Can a second action potential be sent during depolarization and the first part of repolarization? Why or why not?
