What are the different parts of the fornix?
The structure of fornix is divided into 4 parts; the crura, body, commissure and the columns. The crura of fornix begin on each side as a continuation of the fimbria.
What is anterior column of fornix?
The columns (anterior pillars; fornicolumns) of the fornix arch downward in front of the interventricular foramina and behind the anterior commissure, and each descends through the grey matter in the lateral wall of the third ventricle to the base of the brain, where it ends in the mammillary bodies.
Where are the columns of the fornix located?
In the brain, the columns of fornix travel downward in an arch, falling in front of the interventricular foramen (an opening at the center of the brain) and going behind the anterior commissure (a bundle of fibers that connects the brain’s halves).
What structures does the fornix connect?
The fornix connects:
- the hippocampus to the mammillary bodies.
- the hippocampus to the septal nuclei and the nuclei accumbens.
- the mammillary bodies to the anterior nuclei of the thalamus.
What is the structure and function of the fornix?
The fornix is a white matter bundle located in the mesial aspect of the cerebral hemispheres, which connects various nodes of a limbic circuitry and is believed to play a key role in cognition and episodic memory recall.
What is the function of the fornix in the female reproductive system?

What is the fornix made of and what is its function?
Abstract. The fornix is a white matter bundle located in the mesial aspect of the cerebral hemispheres, which connects various nodes of a limbic circuitry and is believed to play a key role in cognition and episodic memory recall.
What is the function of septum pellucidum?
The septum pellucidum acts as a partition between a portion of the lateral ventricles, forming part of the walls of the anterior region of the lateral ventricles. It is made up of a thin two-layered structure that consists of white matter, some neurons, fiber bundles, and blood vessels.
Where do the fibers of the fornix terminate?
The majority of the fibers in the postcommissural fornix terminate in the mammillary body and thalamus.
What’s a fornix?
Definition of fornix : an anatomical arch or fold: such as. a : the junction where the conjunctiva lining the eyelid meets the conjunctiva overlying the sclera.
What is the fornix quizlet?
The fornix (Latin: arch) is a C-shaped bundle of nerve fibers in the brain that carries signals from the hippocampus to the mammillary bodies and then to the anterior nuclei of thalamus.
