posterior commissure

It is named for its location relative to the posterior commissure.

The posterior commissure itself (marked by a star) was unaffected.

Vertically, it is situated above the periaqueductal grey and nucleus of the posterior commissure.

Disruption of the posterior commissure fiber pathway can cause alexia without agraphia.

Tumor limited to the vocal cord(s) (may involve anterior or posterior commissure) with normal mobility.

The epithalamus comprises the habenular trigone, the pineal body, and the posterior commissure.

Posterior Commissure.

The SCO also covers and penetrates the posterior commissure.

In phenotypically abnormal brains, there was some disorganized differentiation of neurons caudal to the posterior commissure.

The posterior commissure interconnects the pretectal nuclei, mediating the consensual pupillary light reflex.

The Talairach coordinate system is defined by making two points, the anterior commissure and posterior commissure, lie on a straight horizontal line.

The aetiology is thought to be damage to the posterior commissure levator inhibitory fibres which originate in the M-group of neurons.

The pedal ganglia are placed beneath the radula sac and joined together by an anterior and a posterior commissure.

Posterior commissure of labia majora (commissura labiorum posterior)

The Arytœnoideus approximates the arytenoid cartilages, and thus closes the opening of the glottis, especially at its back part to eliminate the posterior commissure of the vocal folds.

Although the corpus callosum is the largest white matter tract connecting the hemispheres, some limited interhemispheric communication is still possible via the anterior commissure and posterior commissure.

Other comparisons found that mammals exhibiting USWS have a larger posterior commissure and increased decussation of ascending fibers from the locus coeruleus in the brainstem.

The frenulum of labia minora (fourchette or posterior commissure of the labia minora) is a frenulum where the labia minora meet posteriorly.

Smaller commissures also join the hemispheres, both in eutherian and in other vertebrates, including the anterior commissure (which is present in marsupials), posterior commissure, and hippocampal commissure.

Subsequent axon-axon interactions were also shown to be necessary, as misrouting of retinal axons led to chiasm defasciculaiton, telencephalic and ventral hindbrain projections, or aberrant crossing in the posterior commissure.

The posterior commissure (also known as the epithalamic commissure) is a rounded band of white fibers crossing the middle line on the dorsal aspect of the upper end of the cerebral aqueduct.

A case study described recently in The Irish Medical Journal discussed the role the posterior commissure plays in the connection between the right occipital cortex and the language centers in the left hemisphere.

It is evident from this case study of alexia without agraphia that the posterior commissure plays a vital role in transferring information from the right occipital cortex to the language centers of the left hemisphere.

Examples of these include the great commissures of the brain such as the corpus callosum (Latin, "hard body"; not to be confused with the Latin word "colossus" - the "huge" statue), anterior commissure, and posterior commissure.
