- Which of the following is false? parathyroid hormone is produced by the parathyroid gland parathyroid hormone increases urination of calcium Oparathyroid hormone stimulates osteoclasts parathyroid hormone increases calcium concentration in the bloodarrow_forwardCalcitriol and parathyroid hormone are: synergistic hormones antagonistic hormonesarrow_forwardHypocalcemia, or low levels of calcium, may result in brittle nails, broken bones, muscle cramps, mental confusion, and seizures.Select the FOUR actions below that would help the body to maintain homeostasis if blood calcium levels are low. Low levels of blood calcium are detected by thyroid gland. Low levels of blood calcium are detected by parathyroid gland. Parathyroid hormone is released. Calcitonin is released. Bone is broken down to release calcium. Muscle is broken down to release calcium. Calcium uptake by the kidneys and intestines increases. Calcium uptake by the kidneys and intestines decreases.arrow_forward
- Which of the following is a function of parathyroid hormone? (Select ALL correct answers) Promotes secretion of calcium in kidneys Promotes release of calcium stored in bones Decreases absorption of dietary calcium Promotes reabsorption of calcium in kidneysarrow_forwardWhy does the release of cortisol during the stress response have a negative effect on bone density? Cortisol increases serum calcium to fuel muscle contraction during the fight or flight responseCortisol reduces estrogen production and triggers early menopause Cortisol draws calcium out of the bones to increase serum calcium to fuel muscle contraction during the fight or flight response Cortisol decreases calcium to fuel muscle contraction during the fight or flight responsearrow_forwardBetty has a calcium poor diet and because of her age (menopause years) she is concerned about becoming hypocalcemic (low blood calcium). Once the blood levels of calcium start dropping, the body will compensate for hypocalcemia. Receptors continually feed the brain’s hypothalamus (blood-calcium regulatory center) information on calcium blood levels. The parathyroid gland will be stimulated to release parathyroid hormone (PTH). PTH will stimulate osteoclast cells to break down bone and release the stored calcium to the blood, raising the calcium blood level. a. What is the stimulus?b. What is the control center?c. Identify the control center’s response to the stimuli?d. Does the response stop/reverse the stimuli or enhance the stimuli?e. Is the body’s response a negative or positive feedback?arrow_forward
- Select ALL the statements that are correct. Growth hormone production is inhibited by somatostatin. Growth hormone production is stimulated by the release of the tropic hormone GHRH in the hypothalamus. Growth hormone production is inhibited by IGF-1 which is secreted by the liver. Gigantism and acromegaly differ in that gigantism is due to oversecretion of GHRH, not GH.arrow_forwardHow does Parathyroid Hormone elevate blood calcium levels? by increasing the amount of CA2+ removed from the blood by the kidneys by decreasing the amount of CA2+ absorbed from the gut into the blood by increasing the number and activity of osteoclasts by increasing the number and activity of osteoblastsarrow_forwardDescribe the structural characteristics and function of the parathyroid glands. Describe the particular the role of PTH in calcium homeostasis. Describe the role of calcitonin on calcium homeostasisarrow_forward
