Английская Википедия:Anterior median fissure of spinal cord
Шаблон:Infobox anatomy The anterior median fissure of the spinal cord is a deep midline groove of the anterior/ventral spinal cord.[1]Шаблон:Rp It divides the white matter of the anterior spinal cord nearly in two.[1]Шаблон:Rp The spinal pia mater extends into the fissure to line the surfaces of the spinal cord.[1]Шаблон:Rp
Anatomy
It has an average depth of about 3 mm, but this is increased in the lower part of the spinal cord. It contains a double fold of pia mater. Its floor is formed by a transverse band of white matter - the anterior white commissure - which is perforated by blood vessels on their way to or from the central part of the spinal cord.Шаблон:Citation needed
Relations
The anterior median fissure provides a groove in which the anterior spinal artery sits.Шаблон:Citation needed
Clinical significance
Imaging
The anterior median fissure may be identified on computerized tomography (CT) myelograms, but more commonly on magnetic resonance imaging (MRI) scans. The AMF has a characteristic appearance on MRI scans that differs from the MRI appearance of the central canal.Шаблон:Citation needed
