The hypothalamus (pl.: hypothalami; from Ancient Greek ὑπό (hupó) ' under ' and θάλαμος (thálamos) ' chamber ') is a small part of the vertebrate brain that contains a number of nuclei with a variety of 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 ...
We also measured the anterior commissure in the same blocks of tissue used for the present hypothalamic study (data not shown) and were unable to replicate a report (by Allen and Gorski) that its cross-sectional area is larger in women than in men. [8] Also, a study by Lasco et al. (2002) said:
Most famous parts of the brain highlighted in different colours The human brain anatomical regions are ordered following standard neuroanatomy hierarchies. Functional , connective , and developmental regions are listed in parentheses where appropriate.
Pictured here is a cross-section showing the gross anatomy of the human brain. Neuroanatomy is the study of the structure and organization of the nervous system . In contrast to animals with radial symmetry , whose nervous system consists of a distributed network of cells, animals with bilateral symmetry have segregated, defined nervous systems.
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
They are located on the undersurface of the brain that, as part of the diencephalon, form part of the limbic system. They are located at the ends of the anterior arches of the fornix. [3] They consist of two groups of nuclei, the medial mammillary nuclei and the lateral mammillary nuclei. [4]
A commissure (/ ˈ k ɒ m ə ʃ ər /) is the location at which two objects abut or are joined. The term is used especially in the fields of anatomy and biology. The most common usage of the term refers to the brain's commissures, of which there are at least nine. Such a commissure is a bundle of commissural fibers as a tract that crosses the midline at i
