Which of the following statements concerning control of blood flow through arterioles is true? Select one:...

Which of the following statements concerning control of blood flow through arterioles is true? Select one: a. There are more beta-adrenergic receptors than alpha-adrenergic receptors on arteriolar smooth muscle b. Binding of epinephrine to alpha-adrenergic receptors causes vasodilation. c. Stimulation of vascular smooth muscle by the parasympathetic nervous system causes vasodilation. d. If blood pressure/flow within an organ increases, arterioles in the organ will autoregulate using the myogenic response e. None of the choices are true

Describe the events of hemostasis, including both the intrinsic and extrinsic pathways for blood coagulation. Compare and contrast the specific pattern of blood flow in the the fetal circulation with the circulation of the neonate. In what important ways are they different? Explain what changes occur shortly after birth and the mechanisms involved.

Describe the intrinsic and extrinsic controls of the digestive system. How do mechanoreceptors and chemoreceptors inform the nervous controls about the state of the alimentary canal? Describe how they control the cephalic, gastric, and intestinal phases of stomach’s action.

Describe the mechanisms that limit signaling by the phosphoinositide pathway.

Describe the common features shared by GPCRs and RTKs in their signaling mechanisms, focusing on how they are able to amplify signals. Specifically, how is the signal from one binding event (i.e., the binding of one ligand molecule to an individual receptor) propagated and strengthened? Describe one difference in how GPCRs and RTKs transform extracellular signals into intracellular responses.
