Final answer:
If signaling and hormone release from the hypothalamus were blocked, the mechanism of hormonal stimulation that would be affected is hormonal and neural stimuli.
Step-by-step explanation:
If signaling and hormone release from the hypothalamus were blocked, the mechanism of hormonal stimulation that would be affected is hormonal and neural stimuli. Hormone production and release are primarily controlled by negative feedback. The hypothalamus signals the release of hormones from the anterior pituitary, which then stimulates other endocrine glands to release hormones. Without signaling and hormone release from the hypothalamus, both the hormonal and neural stimuli would be disrupted.
