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 fornices of the vagina (sg.: fornix of the vagina or fornix vaginae) are the superior portions of the vagina, extending into the recesses created by the vaginal portion of cervix. There is an anterior fornix and a posterior fornix.
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.
The anterior commissure (also known as the precommissure) is a tract that connects the two temporal lobes of the cerebral hemispheres across the midline, and placed in front of the columns of the fornix.
The fornix is a C-shaped bundle of axons that begins in the hippocampal formation of both hemispheres, referred to as the fimbria, and extend through the crus of fornix, also known as the posterior pillars. The fimbria section of the fornix is directly connected to the alveus, which is a portion of the hippocampal formation that arises from the ...
The subfornical organ (SFO) is one of the circumventricular organs of the brain. [1] [2] Its name comes from its location on the ventral surface of the fornix near the interventricular foramina (foramina of Monro), which interconnect the lateral ventricles and the third ventricle.
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] Neuroanatomists have often categorized the mammillary bodies as part of the posterior part of hypothalamus. [5]
It is attached to the lower part of the corpus callosum, the large collection of nerve fibers that connect the two cerebral hemispheres. It is attached to the front forward part of the fornix. The lateral ventricles sit on either side of the septum. The septum pellucidum consists of two layers or laminae of both white and gray matter. [1]
