- Notice that organ function is regulated by nerves and by hormones. What is the difference between nerve and hormone control? Why both kinds of controls? Discuss your answers.Oxycodone has a high affinity for the mu receptor, and when it binds to this receptor, it produces a much stronger analgesic response than that of the endorphins produced by the body. Which term is most appropriate for this type of action? O Agonist enzyme interaction Antagonist receptor interaction Agonist receptor interactionHello, I do not understand these questions, can I get help with them, please? Below are 3 statements, explain if each is true/false and why (VERY brief statement) #1: A tropic hormone always increases the size of an endocrine gland. #2: Spontaneous action potentials in the heart are primarily triggered by flux of K+ into cells through If channels. #3: Increasing the frequency of action potentials in motor units generates more tension than increasing the number of motor units.
- Suppose that the circulating concentration of hor-mone is 10–10 M and the Kd for binding to its receptor is 10–8M. What fraction of the receptors will have hormone bound?If a meaningful physiological response occurs when 50% ofthe receptors have bound a hormone molecule, how muchwill the concentration of hormone have to rise to elicit aresponse? The fraction of receptors (R) bound to hormone(H) to form a receptor–hormone complex (R–H) is [R–H]/([R] + [R–H]) = [R–H]/[R]TOT = [H]/([H] + Kd).The action of thyroid hormone to increase the effect of epinephrine would be an example of a: antagonistic effect synergistic effect O priming effect O permissive effect"hich of the following statements is true of the differences between methohexital and midazolam? Multiple Choice Midazolam produces analgesia at small doses whereas methohexital produces amnesia at anesthetic doses. Midazolam induces anesthesia quickly, but methohexital does not. Methohexital has a specific receptor antagonist but midazolam does not. Midazolam is available for rectal administrątion, whereas methohexital is administered intravenously.
- What are the two classes of hormone receptors? How dothey differ in the chemical category of hormones that willbind to them? Give examples of the types of hormonesthat bind to each type of receptorWhich of the following options best describes how epinephrine (adrenaline) is released into the bloodstream? O The sympathetic nervous system stimulates the hypothalamus, which releases sends signals to the anterior pituitary gland, which releases epinephrine into the blood O The sympathetic nervous system stimulates the adrenal medulla, which releases epinephrine into the blood O The parasympathetic nervous system stimulates the adrenal medulla, which releases epinephrine into the blood O The vagus nerve stimulates the adrenal medulla, which releases epinephrine into the blood The parasympathetic nervous system stimulates the adrenal cortex, which releases epinephrine into the bloodAn area called the diencephalon includes the thalamus, which serves as an integrating center for sensory input. Immediately below it, is the _8__ which is critically important for helping us maintain homeostasis. The pituitary gland, which is sometimes referred to as the “master gland” of the endocrine system attaches to this structure by a stalk-like connection, but it is not visible in the specimen we’re looking at.
- Hormones (and/or medicines) which bind to the same receptor and have the same effects are called antagonisticCortisol is known as one of the major stress hormones we produce in response to external stresses we experience. If we wanted to inhibit the production and secretion of Cortisol, what steps that lead to the production to Cortisol could you theoretically block with a drug? Don't just list targets,but explain.your rationale in your answer.Hormone receptor molecules are the key to understanding specific-ity of hormone action on target cells. Describe and distinguish be-tween receptors located on the cell surface and those located in the nucleus of target cells. Name two hormones whose action is medi-ated through each type of receptor.
