Question:

The left hemisphere language network involves white matter tracks connecting the temporal and frontal lobes. One dorsal track connects the posterior temporal cortex and the lateral inferior frontal cortex, and is call the ______, while the other ventral track connects more anterior and medial temporal cortex with the inferior and orbital frontal cortex, and is called the _________.

a. optic chiasm/centre median

b. trigeminal nerve/optic nerve

c.corpus callosum/fornix

d. arcuate fasciculus/uncinate fasciculus

Answer:

The Answer is D.

Explanation:

The arcuate fasciculus (Latin: curved bundle) is a bundle of axons that connects Broca's area and Wernicke's area in the brain .

It is an association fiber tract connecting caudal temporal cortex and inferior frontal lobe.

The role of the arcuate fasciculus relates to the linguistic ability of one. It's' function in language use is best represented by Conduction Aphasia.

Conduction Aphasia refers to a condition caused by damage to the inferior parietal lobule that extends into the subcortical white matter and damages the arcuate fasciculus. This type of aphasia inhibits the patient from repeating unfamiliar sounds.

The uncinate fasciculus  is a hook-shaped bundle of axons that connects the anterior portions of the temporal lobe with the inferior frontal gyrus and the lower surfaces of the frontal lobe.

The arcuate plays a key role in the left hemisphere in language processing and in the right hemisphere in visuospatial processing and some aspects of language processing, such as prosody and semantics.

Answer 2

Answer:

Hi your question lacks the options here is the complete question

The left hemisphere language network involves white matter tracks connecting the temporal and frontal lobes. One dorsal track connects the posterior temporal cortex and the lateral inferior frontal cortex, and is call the ______, while the other ventral track connects more anterior and medial temporal cortex with the inferior and orbital frontal cortex, and is called the

a. optic chiasm/center median

b. trigeminal nerve/optic nerve

c.corpus callosum/fornix

d. arcuate fasciculus/uncinate fasciculus

Answer : arcuate fasciculus/uncinate fasciculus ( D )

Explanation:

arcuate fasciculus is a group of axons that is part of the superior longitudinal fasciculus and they also form an association of fiber tract  while uncinate fasciculus is a group/bundle of axons that links the anterior parts of the temporal lobe with the lower surfaces of the frontal lobe and also with the inferior frontal gyrus of the brain.

The arcuate fasciculus a neural pathway that links the receptive and expressive language centers of the cortex and this helps an individual in listening and understanding a language

The uncinate fasciculus is comprising of different functions which also includes helping an individual in understanding/comprehension of a language
