What is the uncinate fasciculus?

The uncinate fasciculus is one of several long-range white matter association fibre tracts in the human brain. It connects orbitofrontal cortex to the anterior temporal lobes through a direct, bidirectional monosynaptic pathway.

What does the superior longitudinal fasciculus do?

The superior longitudinal fasciculus (SLF) is an extensive white-matter tract that mainly communicates between frontal and parietal lobes, and provides partial communication with the temporal lobe. It interconnects nearly all cortical areas of the lateral cerebral hemisphere.

What is the arcuate fasciculus white matter?

The arcuate fasciculus (AF) is the white matter tract arching (hence the name arcuate) around the end of the Sylvian fissure to connect the posterior temporal region of the brain with specific parts of the frontal lobe.

Where is the arcuate fasciculus?

The arcuate fasciculus (AF) is a white matter bundle that connects the frontal and temporal lobes within each cerebral hemisphere by passing dorsally beneath the parietal lobe.

What is the uncinate process of the nose?

The uncinate process is a wing or boomerang shaped piece of bone. It forms the first layer or lamella of the middle meatus. It attaches anteriorly to the posterior edge of the lacrimal bone, and inferiorly to the superior edge of the inferior turbinate.

Where is superior longitudinal fasciculus?

The superior longitudinal fasciculus (SLF) is an association tract in the brain that is composed of three separate components. It is present in both hemispheres and can be found lateral to the centrum semiovale and connects the frontal, occipital, parietal, and temporal lobes.

What is the arcuate fasciculus and what function does it serve?

The arcuate fasciculus is a bundle of axons that connects the temporal cortex and inferior parietal cortex to locations in the frontal lobe. One of the key roles of the arcuate fasciculus is connecting Broca’s and Wernicke’s areas, which are involved in producing and understanding language.

What is the arcuate fasciculus made of?

axons
The arcuate fasciculus (AF) is a bundle of axons that generally connects the Broca’s area and the Wernicke’s area in the brain. It is an association fiber tract connecting caudal temporal cortex and inferior frontal lobe. Fasciculus arcuatus is latin for curved bundle.

What type of fibers are arcuate fasciculus?

The arcuate fasciculus (AF) is a bundle of axons that generally connects the Broca’s area and the Wernicke’s area in the brain. It is an association fiber tract connecting caudal temporal cortex and inferior frontal lobe. Fasciculus arcuatus is latin for curved bundle.
