Explain how hormones released by endocrine glands can affect specific target cells in the body. Provide an example of a type of target cell.

• Hormones travel through the bloodstream and bind to specific receptors on target cells, such as muscle cells, to regulate their activity.

• Hormones are released into the digestive tract and affect all cells equally.

• Hormones only affect the cells that are closest to the gland that released them.

• Hormones are stored in the skin and released when needed.

What is the method called where sensory receptors send messages to the hypothalamus, which signals the sympathetic nervous system to stimulate the adrenals to release stress hormones?

• Neural stimulation

• Negative feedback

• Circadian rhythm regulation

• Hormonal cascade

• Neural stimulation

• Hormonal cascade

What happens when the calcium (Ca2+) level in the blood becomes too high?

• The parathyroid glands are inhibited and less parathyroid hormone is released.

• The parathyroid glands are stimulated and more parathyroid hormone is released.

• The thyroid gland releases more calcitonin.

• The adrenal glands release more cortisol.

If the calcium level in the blood is too low, what is the immediate effect on the parathyroid glands?

• They are stimulated to release more parathyroid hormone.

• They are inhibited from releasing parathyroid hormone.

• They release less parathyroid hormone.

• They stop functioning entirely.
