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.
Fornix (pl.: fornices, Latin for "arch") can refer to: Fornix or throat scale, a bowed prolongation of the corolla in Boraginaceae ; Fornix of the brain; Fornix conjunctiva, a part of the conjunctiva; Fornix vaginae, also called the vaginal fornix; An early type of Roman triumphal arch
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 ...
Carrying a baby to term, i.e. parity, is associated with a significant increase in the length of the vaginal fornix. [1] The potential effect of parity may be the result of a stretching and elongation of the birth canal at the time of vaginal birth. [1]
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]
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 anterior nuclei receive afferents from the hippocampus and subiculum directly via the fornix, and indirectly via the mammillary bodies and mammillothalamic tract (MTT). They send efferent fibers to the cingulate gyrus, limbic, and orbitofrontal cortex. [1] The anterior nuclei of the thalamus display functions pertaining to memory.
