The hypothalamus is divided into four regions (preoptic, supraoptic, tuberal, mammillary) in a parasagittal plane, indicating location anterior-posterior; and three zones (periventricular, intermediate, lateral) in the coronal plane, indicating location medial-lateral.
Oct 30, 2023 · The hypothalamus is a paired structure that forms part of the diencephalon. It sits below the hypothalamic sulcus within the medial wall of the third ventricle, which separates the hypothalamus from the thalamus above.
May 6, 2024 · The hypothalamus produces and secretes not only neurotransmitters and neuropeptides but also several neurohormones that alter anterior pituitary gland function and two hormones, vasopressin ( antidiuretic hormone) and oxytocin, that act on distant target organs.
May 1, 2023 · 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.
Oct 10, 2022 · The hypothalamus is centrally located in the brain, and it connects to the brainstem via the dorsal longitudinal fasciculus, cerebral cortex via the medial forebrain bundle, hippocampus via the fornix, amygdala via the stria terminalis, thalamus via the mammillothalamic tract, pituitary via median eminence, and retina via the retinohypothalamic ...
Jan 17, 2023 · Key Points. The hypothalamus produces and secretes a wide variety of neurohormones that lead to the release or inhibition of pituitary gland. hormone. The posterior pituitary is composed of tissue derived from the hypothalamus, whereas the anterior pituitary is derived from epithelial tissue.
Overview. The hypothalamus is a region of the brain composed of many small nuclei with diverse functions. Located above the midbrain and below the thalamus, the hypothalamus makes up the ventral...
