Dorsal Column Medial Lemniscus Pathway

The gracilis and cuneate fasciculi also known as the dorsalposterior columns are two ascending pathways located side-by-side in the posterior funiculus of the spinal cord. Lets now take a look at each pathway more closely.

. Lets start with the dorsal column-medial lemniscus system which is a sensory pathway that transmits delicate sensations like vibration. Although the test can be subject to error accuracy is based solely on the patients ability to follow the directions and steps of the examination. Supplies the tonsil and hemisphere.

The posterior inferior cerebellar artery gives off the following arteries. Information travels from the receptors in the organ of Corti of the inner ear cochlear hair cells to the central nervous system carried by the vestibulocochlear nerve CN VIII. In neuroanatomy the dorsal column nuclei are a pair of nuclei in the dorsal columns in the brainstem.

Occasionally a small vertebral artery will terminate into a common AICA-PICA. The name refers collectively to the cuneate nucleus and gracile nucleus which are present at the bottom of the medulla oblongataBoth nuclei contain second-order neurons of the dorsal columnmedial lemniscus pathway which carries fine touch and proprioceptive. Supplies the vermis and adjacent hemisphere.

They carry fine and discriminative touch as well as proprioceptive sensationsTogether with the medial longitudinal fasciculus these tracts. The last ascending tract called spinocerebellar tract is a sensory pathway that is in charge of sending sensory information that will help coordinate the muscles in the trunk and the limbs. The auditory pathway conveys the special sense of hearing.

The Romberg test does not require any equipment or instrumentation to diagnose a proprioceptive impairment or injury to the dorsal column medial lemniscus pathway. This pathway ultimately reaches the primary auditory cortex for conscious perceptionIn addition unconscious processing of. The medial lemniscus is part of the dorsal columnmedial lemniscus pathway which ascends from the skin to the thalamus which is important for somatosensation from the skin and joints therefore lesion of the medial lemnisci causes an impairment of vibratory and.
