Which of the following statements is true for pancreas ?Group of answer choicesThe alpha cells of the pancreas secrete insulin.Hypersecretion of insulin causes diabetes mellitus.Insulin causes an increase in the blood sugar level.Glucagon and insulin are antagonists of each other.

Which one of the following statements regarding drugs that affect blood glucose level is correct?Group of answer choicesSodium-glucose co-transporter-2 inhibitors decrease the excretion of glucose.Glucagon-like peptide-1 receptor agonists increase glucagon secretion.Biguanides enhance the digestion and absorption of carbohydrates.Sulfonylureas increase insulin release by binding to the ATP-sensitive potassium channel.

Which statement is accurate?(A) Hormones that differ in effect reach their target cells bydifferent routes through the body.(B) Pairs of hormones that have the same effect are said tohave antagonistic functions.(C) Hormones are often regulated through feedback loops.(D) Hormones of the same chemical class usually have thesame function

You have been introduced to the general concepts of control theory. With this background, study each of the following statements. Which statement is INCORRECT?Question 12Select one:a.We avoid dangerous hypoglycaemia between meals because insulin follows the concept of proportional control and decreases in response to low blood glucose levels.b.Feedforward control occurs when an anticipatory neural signal is sent from the brain to the structures involved in regulating critical physiological variables.c.From a physiological perspective, we consider that a control/regulatory system has five key features: an input signal, receptors, a central integrator, an effector organ and a physiological outcome.d.In physiology, the word “control” is used to describe changes to effector organs that are specifically designed to result in the regulation of variables in a homeostatic range. e.Negative feedback occurs when the output signal enhances the original effect of the stimulus, whereby the direction of change is in the same direction as the initial change in the variable.
