Spinal Cord Histology. A drawing of a transverse section through the T10 spinal segment is shown on the right. The spinal cord is bilaterally symmetrical. Ventrally, the halves are separated by a ventral median fissure (into which pia mater invaginates) Spinal Cord. Peripheral nerves contain sensory neurons and motor neurons that connect with the spinal cord. In cross-section, the spinal cord is divided into the butterfly-shaped grey matter and surrounding white matter. Gray Matter - butterfly-shaped region that contains nerve cell bodies and supporting glial cells An introduction to the histology of the spinal cord, as presented by the University of Rochester's Pathology IT Program Histology home page. Nervous system: Spinal cord: Slide: Spinal cord section HE 2-21. Microscope at 40X.

The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column.It encloses the central canal of the spinal cord, which contains cerebrospinal fluid.The brain and spinal cord together make up the central nervous system (CNS). In humans, the spinal cord begins at the occipital. Histology Guide - a virtual histology laboratory with zoomable images of microscope slides and electron micrographs. Describe the white matter of the spinal cord: Surrounds the gray matter; Ascending and descending axons (bundled into tracts) Supporting glial cells
Fig. 1E shows what remained of the sample after sectioning all but the last millimeter of spinal cord, illustrating the arrangement of agarose, gelatin, and spinal cord during sectioning. It was important to match the mechanical properties of the gelatin and agarose to avoid skipped or inconsistent-thickness vibratome sections (fixed 10% gelatin and unfixed 4% agarose in this case) Spinal cord, major nerve tract of vertebrates, extending from the base of the brain through the canal of the spinal column. It is composed of nerve fibres that mediate reflex actions and that transmit impulses to and from the brain. Like the brain, the spinal cord is covered by thre

After you have finished reading this page, take a look at this section from a diseased spinal cord, and try to work out what's wrong. This is a section of WHITE matter, stained in the same way as the picture above, at a higher magnification . In this particular stain (H&E) the grey matter can be seen in a slightly darker shade than the white matter. The relative size of the grey matter is small compared to the white matter and therefore the level of the cross-section is unlikely to be around the level of any limbs
No spinal cord histology showed signs of ischemia, even in specimens with a significant large parent vessel (vertebral artery and aorta) occlusion due to atherosclerosis. Neuropathology of these adjacent cord segments revealed no signs of ischemia or demyelination . Intramedullary ependymomas occur most often in the cervical region. 45 % affect this area only; whereas in 25 % of cases, the tumors are localized in both the cervical and upper part of the thoracic sections Spinal Cord 400X The largest cells in the spinal cord are motor neurons (mn). The small dark spot inside the cell is its nucleus. These cells are located mostly in the anterior or ventral gray matter. Because this is a section, and not a smear, you cannot see the processes. The small dark spots are the nuclei of supporting cells (sc) Regions of human spinal cord.

The authors are obviously highly experienced in these tumors. There is quite a bit of literature published with the same findings as the authors: tumor histology predicts degree of resectability in spinal cord tumors Spinal Cord Nuclei. The prominent nuclei (groups of neuron cell bodies) in the spinal cord are the: Marginal zone (MZ, posterior marginalis) - located at the tip of the dorsal horn, and is important for relaying pain and temperature sensation to the brain. Substantia gelatinosa (SG) - located at the top of the dorsal horn, the SG is important for relaying pain, temperature and light touch.
Spinal cord ischemic injury is an uncommon but devastating entity in clinical practice. 1 A substantial proportion of the cases occur after operations on the descending thoracic or thoracoabdominal aorta. 2 Spinal cord ischemia may also represent an important secondary injury mechanism after spinal cord trauma. 3 Stenonis, as quoted by Zivin and DeGirolami, 4 was the first to describe the.

Introduction. Spinal cord injury (SCI) results in permanent sensorimotor deficits and remote neurodegeneration and reorganization along the neuroaxis, all of which have strong relationships with clinical outcomes (1,2).These relationships are of high clinical relevance because in vivo neuroimaging assessing volumetric and microstructural changes of the central nervous system might help to. Brain, dura, skull, spine/ spinal cord, neural cell clusters/ ganglia and CSF are available, as may specific nerves / neuromuscular junctions. Please note that the gut is also particularly rich in neural tissue, and is reported to share certain CNS characteristics, if you would like to examine another set of nerves for comparison CENTRAL NERVOUS SYSTEM Slide 3 Spinal cord. Note the H-shaped central gray matter (containing many neurons) and the surrounding white matter.The gray matter is organized as posterior (dorsal) horns and anterior (ventral) horns.Also note the pia mater that is closely adherent to the spinal cord. Identify the ependymal cells surrounding the central canal
The spinal cord, due to its morphology, constrains pathology to a ~10-20 mm cylinder. As such the morphology of lesions is less helpful than in the brain. In this case, the prominent vessels are very helpful in suggesting the diagnosis 1. Name this specific region of the spinal cord. 2. Is this gray or white matter? SLIDE 2. 3.
