What are the columns of the fornix?
The columns of fornix are known as anterior pillars and fornicolumns. These exist within the brain. Fornix is Latin for ‘vault’ and ‘arch’, representing the shape of the columns of fornix. The columns begin on either side of the brain, and separately are known as the crus of the fornix.
What are the three parts of the fornix?
body, commissure and the columns. The crura of fornix begin on each side as a continuation of the fimbria. The curve over the hypothalamus and join in the midline to form the body of the fornix.
What structure is below the fornix?
The fornix is a C-shaped bundle of white matter that is found in the mesial aspect of the cerebral hemispheres, below the corpus callosum….Fornix of the brain.

Where does the column of fornix ends?
Columns. 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 does the fornix start and end?
The fornix originates in the hippocampus, where it emerges from a collection of fibers called the fimbria. It then stretches up and around the thalamus toward the front of the brain. When it reaches a tract called the anterior commissure, it branches downward.
What structures does 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 are the two columns of the foot?
The foot is sometimes described as having two columns (Figure 3). The medial column is more mobile and consists of the talus, navicular, medial cuneiform, 1st metatarsal, and great toe. The lateral column is stiffer and includes the calcaneus, cuboid, and the 4th and 5th metatarsals. Figure 3: Columns of the Foot
What is the anatomy of the foot?
The anatomy of the foot. The foot contains a lot of moving parts – 26 bones, 33 joints and over 100 ligaments. The foot is divided into three sections – the forefoot, the midfoot and the hindfoot. The forefoot. This consists of five long metatarsal bones and five shorter bones that form the toes (phalanges).
What is the anatomy of the fornix?
The body of the fornix anteriorly divides into two columns. The two columns diverge slightly lateral to the midline. These columns then curve downwards. They arch just in front of the interventricular foramen.
What bones make up the medial column of the foot?
The medial column is more mobile and consists of the talus, navicular, medial cuneiform, 1st metatarsal, and great toe. The lateral column is stiffer and includes the calcaneus, cuboid, and the 4th and 5th metatarsals. The foot is comprised of 28 bones (Figure 1). Where two bones meet a joint is formed –often supported by strong ligaments.
