MICROANATOMY

Detailed explanation-1: -It communicates with your posterior lobe by tissue called the pituitary stalk. Your hypothalamus sends signals in the form of releasing hormones to tell the anterior and posterior pituitary when to release (secrete) its hormones.

Detailed explanation-2: -The hypothalamus is located in the ventral brain above the pituitary gland and below the third ventricle. The afferent pathways to the hypothalamic nuclei, the majority of which are located in the anterior hypothalamus, arise from the brainstem, thalamus, basal ganglia, cerebral cortex, and olfactory areas.

Detailed explanation-3: -For each system, the hypothalamus secretes releasing hormones (i.e., CRH, GnRH, and TRH) that act on the pituitary gland. In response to those stimuli, the pituitary gland releases ACTH, gonadotropins (i.e., LH and FSH), or TSH. ACTH activates the adrenal glands to release cortisol, which induces metabolic effects.

Detailed explanation-4: -The hypothalamus is an area of the brain that produces hormones that control: Body temperature. Heart rate. Hunger.

Detailed explanation-5: -Some of the most important hormones produced in the anterior region of the hypothalamus include: Corticotropin-releasing hormone (CRH). CRH is involved in the body’s response to both physical and emotional stress. It signals the pituitary gland to produce a hormone called adrenocorticotropic hormone (ACTH).
