  2. Human brain - Wikipedia

    The larger arteries throughout the brain supply blood to smaller capillaries. These smallest of blood vessels in the brain, are lined with cells joined by tight junctions and so fluids do not seep in or leak out to the same degree as they do in other capillaries; this creates the bloodbrain barrier. [44]

  3. Cerebral circulation - Wikipedia

    en.wikipedia.org/wiki/Cerebral_circulation

    Cerebral blood flow (CBF) is the blood supply to the brain in a given period of time. [8] In an adult, CBF is typically 750 millilitres per minute or 15.8 ± 5.7% of the cardiac output . [ 9 ] This equates to an average perfusion of 50 to 54 millilitres of blood per 100 grams of brain tissue per minute.

  4. Circumventricular organs - Wikipedia

    en.wikipedia.org/wiki/Circumventricular_organs

    Classified as a sensory circumventricular organ (along with the SFO and AP), [13] the vascular organ of lamina terminalis (VOLT) is situated in the anterior wall of the third ventricle. [22] Characteristically of the CVOs, it lacks the tight endothelial blood brain barrier.

    This article contains a list of organs in the human body. It is widely believed that there are 79 organs (this number goes up if you count each bone and muscle as an organ on their own, which is becoming a more common practice [1] [2]); however, there is no universal standard definition of what constitutes an organ, and some tissue groups' status as one is debated. [3]

    en.wikipedia.org/wiki/Brain

    The brain is small and simple in some species, such as nematode worms; in other species, such as vertebrates, it is a large and very complex organ. [4] Some types of worms, such as leeches, also have an enlarged ganglion at the back end of the nerve cord, known as a "tail brain". [17]

  7. Pineal gland - Wikipedia

    en.wikipedia.org/wiki/Pineal_gland

    The pineal gland is located in the epithalamus, near the center of the brain, between the two hemispheres, tucked in a groove where the two halves of the thalamus join. [4] [5] It is one of the neuroendocrine secretory circumventricular organs in which capillaries are mostly permeable to solutes in the blood. [6]

  9. Vascular organ of lamina terminalis - Wikipedia

    en.wikipedia.org/wiki/Vascular_organ_of_lamina...

    In a situation of lowered blood volume, secretion of renin by the kidneys results in the production of angiotensin II, which stimulates receptors in the VOLT and subfornical organ to complete a positive feedback loop. [9] [12] [13] These neurons also project to the median preoptic nucleus which is involved in controlling thirst. [11] [9] [12]
