Question

factors that trigger hormonal stimulation
endocrine cells that increase hormone secretion in response to other hormones are controlled by
positive stimuli
humoral stimuli
hormonal stimuli
neural stimuli

Explanation:

Hormonal stimuli refer to the regulation of hormone secretion by other hormones. In this case, endocrine cells increase hormone secretion in response to other hormones, which is the definition of hormonal stimuli. Positive stimuli generally amplify a response but not specifically in the context of hormone - on - hormone regulation. Humoral stimuli involve changes in the extracellular fluid (like ion or nutrient levels). Neural stimuli involve nerve impulses.

Answer:

hormonal stimuli
