B) neurons in the amygdala; hypothalamus

Quizplus · Accepted Answer

Ghrelin is primarily manufactured by cells in the stomach and stimulates the pituitary gland to secrete growth hormone. Therefore, option A is the correct choice. Option B is incorrect because ghrelin is not primarily manufactured by neurons in the amygdala and does not stimulate the hypothalamus. Option C is incorrect because ghrelin is not primarily manufactured by cells in the spinal cord and does not stimulate the amygdala. Option D is incorrect because ghrelin does not stimulate stretch receptors in the stomach or the pancreas.
