What artery supplies the fornix?
The fornix derives its blood supply mainly from the short medial central arteries, which are branches of the proximal anterior cerebral artery. These are 4 to 10 in number and enter the brain through the anterior perforated substance.
What does the fornix of the brain do?
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.
Where does the fornix end?
The body of the fornix continues in midline, just beneath the corpus callosum, separated from it via septum pellucidum. in the mammillary bodies. ends in the anterior nucleus of thalamus. Regarding the physiology of the fornix, no specific function is associated with with this structure.
Is the fornix part of the brain?
The fornix (meaning “arch” in Latin) 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.
What are the anatomical structures connecting the cerebral hemispheres brain?
A fissure or groove that separates the two hemispheres is called the great longitudinal fissure. The two sides of the brain are joined at the bottom by the corpus callosum. The corpus callosum connects the two halves of the brain and delivers messages from one half of the brain to the other.
What is cervical fornix?
The fornices are superior recesses of the vagina formed by the protrusion of the cervix into the vaginal vault. There is a large posterior fornix and a smaller anterior fornix with two small lateral fornices.
What are fissures in the brain?
A fissure is a deeper grove and is often used interchangeably with sulcus. The cerebrum is divided into a left and right hemisphere by a longitudinal fissure that goes by many different names: longitudinal fissure, cerebral fissure, median longitudinal fissure, interhemispheric fissure.
How many fissures does the brain have?
The inner surfaces of the two hemispheres are convoluted by gyri and sulci just as is the outer surface of the brain….
