posterior column

You must have read his little book on sclerosis of the posterior columns.

Some fibers are unmyelinated and scattered through the posterior column.

It may be caused by disease of the sensory cortex or posterior columns.

The posterior columns are assessed by the person's ability to feel the vibrations of a tuning fork on the wrists and ankles.

He noticed and was puzzled by degenerations of the posterior columns that could cause an 'inability to regulate motor power'.

The new pathway is located in the posterior columns, traditionally believed to mediate light touch and kinesthesia.

At the medulla, the medial lemniscus is orientated perpendicular to the way the fibres travelled in the posterior columns.

A few of its fibers pass to the lateral column of the same side and to the gray matter at the base of the posterior column.

The posterior column (dorsal column) refers to the area of white matter in the dorsomedial side of the spinal cord.

The median nerve pathway then joins the posterior columns, sending off collateral branches to synapse in the midcervical cord.

Further conduction in the posterior columns passes through the synapse at the cervicomedullary junction and enters the lemniscal decussation.

The degenerating nerves are in the dorsal columns (posterior columns) of the spinal cord (the portion closest to the back of the body).

The disease is characterized by the degeneration of both the lateral and posterior columns, which results in symptoms such as a spastic ataxic gait and paranoia.

Sclerosis and degeneration of dorsal root ganglion, spinocerebellar tracts, Lateral corticospinal tracts, and posterior columns.

In brain MRI, there is often an increased T2 signalling at the posterior columns of the spinal cord in patients with myelopathy caused by copper deficiency.

It can also be evoked when a practitioner pounds on the posterior cervical spine while the neck is flexed; this is caused by involvement of the posterior columns.

SCD also has the same high T2 signalling intensities in the posterior column as copper deficient patient in MRI imaging.

Because the posterior columns are also called dorsal columns, the pathway is often called the dorsal column-medial lemniscus system, or DCML for short.

MRI- T2 images may reveal increased signal within the white matter of the spinal cord predominately in the posterior columns but also may be in the spinothalamic tracts.

The fasciculus cuneatus is triangular on transverse section, and lies between the fasciculus gracilis and the posterior column, its base corresponding with the surface of the medulla spinalis.

Cells in this nucleus project to deeper laminae of the spinal cord, to the posterior column nuclei, and to other supraspinal relay centers including the midbrain, thalamus, and hypothalamus.

It extends throughout the entire length of the medulla spinalis, and on transverse section appears as an oval area in front of the posterior column and medial to the posterior spinocerebellar tract.

Longet is remembered for extensive research of the autonomic nervous system, and physiological experiments of the anterior and posterior columns of the spinal cord in regards to sensory and motor functionality.

This area includes the dorsal columns (also called the posterior columns) which contains the fasciculus gracilis and, higher in the body, the fasciculus cuneatus, which are separated by a partition of glial cells.

Histologically, neuromata contain a characteristic adventitious plaque of tissue composed of hyperplastic, interlacing bands of Schwann cells and myelinated fibers overlay the posterior columns of the spinal cord.
