    The hypothalamus is located below the thalamus and is part of the limbic system. [1] It forms the basal part of the diencephalon. All vertebrate brains contain a hypothalamus. [2] In humans, it is about the size of an almond. [3] The hypothalamus has the function of regulating certain metabolic processes and other activities of the autonomic ...

    In vertebrates, the part of the brain that plays the greatest role is the hypothalamus, a small region at the base of the forebrain whose size does not reflect its complexity or the importance of its function. [104] The hypothalamus is a collection of small nuclei, most of which are involved in basic biological functions.

    The hypothalamus also plays a role in thermal regulation, and when stimulated by the immune system, is capable of generating a fever. The hypothalamus is influenced by the kidneys: when blood pressure falls, the renin released by the kidneys stimulates a need to drink. The hypothalamus also regulates food intake through autonomic signals, and ...

    [2] [3] It overlies the paraventricular nucleus of hypothalamus, [4] and is involved in the secretion of vasopressin. [2] The VOLT monitors the presence of peptides and macromolecules in the bloodstream, and conveys the information to the hypothalamus. [3] It is one of the three sensory circumventricular organs of the brain. [5] The other four ...

    The hypothalamus and the anterior pituitary are two out of the three endocrine glands that are important in cell signaling. They are both part of the HPA axis which is known to play a role in cell signaling in the nervous system. Hypothalamus: The hypothalamus is a key regulator of the autonomic nervous system.

    The cell bodies of these neurons are located in various nuclei of the hypothalamus or in closely related areas of the basal brain, mainly in the medial zone of the hypothalamus. [ 1 ] [ 2 ] All or most of the axons of the parvocellular neurosecretory cells project to the median eminence , at the base of the brain, where their nerve terminals ...

    executive functions; ADHD; addiction; schizophrenia; Nigrostriatal pathway: The nigrostriatal pathway transmits dopaminergic neurons from the zona compacta of the substantia nigra [8] to the caudate nucleus and putamen. The substantia nigra is located in the midbrain, while both the caudate nucleus and putamen are located in the dorsal striatum ...

  9. Endocrine gland - Wikipedia

    en.wikipedia.org/wiki/Endocrine_gland

    The hypothalamus regulates the hormonal output of the anterior pituitary and creates two hormones that it exports to the posterior pituitary for storage and later release. Four of the six anterior pituitary hormones are tropic hormones that regulate the function of other endocrine organs. Most anterior pituitary hormones exhibit a diurnal ...
