The fornix (from Latin: fornix, lit. 'arch'; pl.: fornices) is a C-shaped bundle of nerve fibers in the brain that acts as the major output tract of the hippocampus. The fornix also carries some afferent fibers to the hippocampus from structures in the diencephalon and basal forebrain. The fornix is part of the limbic system. While its exact ...
The human brain anatomical regions are ordered following standard neuroanatomy hierarchies. Functional , connective , and developmental regions are listed in parentheses where appropriate. Hindbrain (rhombencephalon)
A major output goes via the fornix to the lateral septal area and to the mammillary body of the hypothalamus (which the fornix interconnects with the hippocampus). [21] The hippocampus receives modulatory input from the serotonin, norepinephrine, and dopamine systems, and from the nucleus reuniens of the thalamus to field CA1.
Hippocampus anatomy describes the physical aspects and properties of the hippocampus, a neural structure in the medial temporal lobe of each cerebral hemisphere of the brain. It has a distinctive, curved shape that has been likened to the sea-horse creature of Greek mythology , and the ram's horns of Amun in Egyptian mythology .
This is a list of human anatomy mnemonics, categorized and alphabetized.For mnemonics in other medical specialties, see this list of medical mnemonics.Mnemonics serve as a systematic method for remembrance of functionally or systemically related items within regions of larger fields of study, such as those found in the study of specific areas of human anatomy, such as the bones in the hand ...
The trisynaptic circuit is a neural circuit in the hippocampus, which is made up of three major cell groups: granule cells in the dentate gyrus, pyramidal neurons in CA3, and pyramidal neurons in CA1. The hippocampal relay involves three main regions within the hippocampus which are classified according to their cell type and projection fibers.
Injection of angiontensin has actually been long used to induce hypertension in animal test models to study the effects of various therapies and medications. In such experiments, it has been observed that an intact and functioning subfornical organ limits the increase in mean arterial pressure due to the increased angiotensin. [12]
In human neuroanatomy the word is somewhat distorted, becoming synonymous with "superior" in the forebrain, i.e. in the direction of the roof of the cranial cavity"cranial cavity and thence to the body. "Ventral" in the central nervous system also refers to the rostro-caudal axis, which changes within the head.
