The hypothalamus is responsible for activating the sympathetic branch of the autonomic nervous system in response to stressors. This activation stimulates the adrenal gland to secrete adrenaline, which is a key component of the first stage of the general adaptation syndrome. The medulla oblongata is also involved in regulating the autonomic nervous system, but it is not the primary brain region responsible for activating the sympathetic branch in response to stress. The somatic nervous system is responsible for voluntary muscle movement and is not directly involved in the stress response.
