A complete cross-section of the spinal cord was observed during surgery. Post operation, a decrease in blood pressure led to a thoracotomy and thoracic endovascular aortic repair due to a crack in the descending aorta wall. Thoracolumbar fracture-dislocations, particularly in patients with ankylosing...

Fig. 2.3. Cross sections of the spinal cord at various levels; note the large lateral extensions of the anterior horns in C5, C8, and L5. In the mantle layer of each plate, neurons are arranged in functional columns. General visceral afferent and efferent neurons are near each other, in...
The spinal cord relays nerve signals between the spinal nerves and the brain. Each spinal nerve has two roots. One contains sensory neurons bringing incoming signals from sense receptors. The other …
Cross section The spinal cord is made of gray and white matter just like other parts of the CNS. It shows four surfaces: anterior, posterior, and two lateral. They feature fissures (anterior) and sulci (anterolateral, posterolateral, and posterior). The gray matter is the butterfly-shaped ce...
The meaning of SPINAL CORD is the cord of nervous tissue that extends from the brain lengthwise along the back in the spinal canal, gives off the pairs of spinal nerves, carries impulses to and from the brain, and serves as a center for initiating and co

(b) Representative photomicrographs of cross- section of spinal cord stained with hematoxylin and eosin, Mac-1 immunohistochemisty and luxol blue stain at 28 days after injury. With increasing severity of injury, there is evidently increasing cell damage, macrophage/microglial reactivity and myelin ...

which correspond to the origins of the nerves to the upper and lower extremities, respectively. A cross section of the cord reveals a mixture of white matter and gray matter (Fig. 20-5). The gray matter, in the shape of an H, surrounds the central canal and contains thecell bodiesof ...
