QUESTION 56 Which of the following is true in relation to calcium homeostasis.

. Which of the following isare true for Homeostasis. Parathyroid hormone acts directly on bone and kidney and indirectly on the intestine. Asked Sep 26 2016 in Anatomy Physiology by Bayleigh.

Hypercalcemia can result in lethargy sluggish reflexes constipation and loss of appetite confusion and coma. The various glands in the body work to regulate numerous body processes. Calcitonin acts to increase the number and activity of osteoblasts.

Parathyroid hormone increases calcium loss from the kidney. Which of the following statements regarding calcium homeostasis is true. Parathyroid hormone acts to decrease osteoclast activity.

B Increased calcitonin levels will cause increased blood calcium levels. It takes time to deliver hormones to the cells-The effects of hormones are long lasting-Hormones are targeted to specific organs within the body-Hormones are secreted by glands not axons. The original calcium hypothesis suggests that a large sustained influx of calcium into cells initiates cell death signalling cascades.

Calcium homeostasis ie maintaining a blood calcium level of about 10 mgdL is critical for normal body functions. C High calcium levels cause bone resorption D Parathyroid hormone causes an increase in osteoblast activity. Parathryoid hormone is released when blood calcium levels are high.

Which of the following statements regarding calcium homeostasis is true. B Inhibition of osteoclast activity helps restore high extracellular calcium concentration to normal levels. Select all that apply Most homeostatic mechanisms rely on positive feedback where the output eventually turns off the stimulus.

A Parathyroid hormone is the single most important regulator of calcium levels in the blood. Parathyroid hormone inhibits osteoclast activity When blood calcium levels are too low osteoclast activity increases Increased osteoblast activity increases blood calcium levels Parathyroid hormone increases calcium loss from the kidney Calcitonin elevates blood calcium levels. For example a sustained level of intracellular free calcium.

The Homeostasis process continuously works to maintain internal regulations on three. Some homeostatic mechanisms rely on negative feedback where the output from the effector enhances the original stimulus. Which of the following statements regarding calcium homeostasis is not true.

Increased osteoblast activity increases blood calcium levels. Increased osteoblast activity increases blood calcium levels. A Extracellular calcium concentration is monitored in the parathyroid.

Parathyroid hormone inhibits osteoclast activity. Calcium and phosphate homeostasis is complex yet three important hormones are responsible for modulating most of the extracellular control of these minerals. While much of this original tenant remains true recent findings suggest that the role of calcium in traumatic neuronal injury may be more complex.

Parathyroid hormone inhibits osteoclast activity. Hypocalcemia can result in problems with blood coagulation muscle contraction nerve functioning and bone strength. Calcitonin elevates blood calcium levels.

Which of the following is true about calcium homeostasis. The gland that works to regulate the homeostasis of calcium is called the parathyroid gland. Calcitonin acts to increase blood calcium levels.

QUESTION 57 Which of. When blood calcium levels are too low osteoclast activity increases. The human body maintains homeostasis or Internal Environment by controlling different Physical and chemical reactions such as body temperature regulation Maintenance of blood pH blood glucose levels to fluid balance Concentration of sodium potassium and calcium ion.

Which of the following is true about calcium homeostasis--Increased calcitonin levels causes increased blood calcium levels-- High calcium levels cause bone resorption -- Parathyroid hormone causes an increase in osteoblast activity-- Parathyroid hormone is the single most important regulator of calcium levels in the blood. Precise maintenance of the physiologic levels of both extracellular and intracellular ionized calcium is essential to life.
