Upon entry of meal in the digestive system there is secretion of insulin increases to promote the cellular uptake and storage of ingested nutrients. Which of the following mechanism is responsible for this event:Select one:a. Negative feedbackb. Adaptivec. Feed forwardd. Positive feedbackClear my choice

InsulinMultiple Choicehelps glucose enter cells.increases blood glucose levels after meals.stimulates cells to break down glycogen for energy.is released during fasting periods, such as between meals.

When insulin is released it causesGroup of answer choicesThe liver to decrease fatty acid synthesisMuscle and adipose tissue to increase glucose uptakeThe liver to decrease glucose uptakeLiver and muscle to increase glycogen breakdown

Hunger is stimulated by the hormone,

Which of the following is the best description of the homeostatic mechanism of negative feedback?Adjustment made by the body to return itself to normal after detecting a changeAdjustment made by the body to decrease the rate of metabolismAdjustment made by the body to increase the rate of metabolismThe negative thoughts that occur when the body is in fight or flight mode2What is the role of the pituitary gland in regulating metabolic rate? It detects the levels of glucose in the bloodIt releases thyroxineIt releases thyroid stimulating hormoneIt controls the amount of oxygen entering the body3What happens when the amount of thyroid stimulating hormone released from the pituitary gland increases? More thyroxine is released from the thyroid, metabolic rate increasesLess thyroxine is released from the thyroid, metabolic rate decreasesMore thyroxine is released from the thyroid, metabolic rate decreasesLess thyroxine is released from the thyroid, metabolic rate increases4Which gland is located at the top of your kidneys?Adrenal glandsPituitary glandSweat glandThyroid gland5Which of the following is not a ‘flight or fight’ response caused by the release of adrenalin? Increased heart rate and breathingBreakdown of glycogen reserves to produce glucoseBlood redirected from skeletal muscles to digestive systemDilation of pupils6Which of the following hormones is not controlled by a negative feedback mechanism?AdrenalinADHInsulinThyroxine

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.
