What serves as the positive stimulus in the control of thyroid hormone secretion?

A) increased metabolic rate
B) high thyroid hormone levels in blood
C) low thyroid hormone levels in blood
D) high thyroid releasing hormones in blood
E) action potential in neurosecretory cells

Thyroid Hormone

Hormones produced by the thyroid gland that regulate metabolism, energy generation, and growth and development.

Metabolic Rate

The rate at which the body uses energy to maintain basic functions at rest; influenced by age, gender, weight, muscle mass, and activity level.

Neurosecretory Cells

Specialized neurons that produce and release hormones into the blood or surrounding tissue, bridging the nervous and endocrine systems.

  • Familiarize oneself with the function of hormones in metabolic regulation and the sustenance of energy homeostasis.
  • Elucidate the feedback loops that control endocrine system functioning.

Final Answer :
C
Explanation :
In the control of thyroid hormone secretion, low levels of thyroid hormone in the blood serve as the positive stimulus. This triggers the release of thyroid-stimulating hormone (TSH) from the anterior pituitary gland, which stimulates the thyroid gland to produce and secrete more thyroid hormone.
