Brazilian Waxing In Portsmouth New Hampshire

Histology Histology of the Cerebellum Spinal Cord


Spinal anterior horn. HEX40.
histological picture anterior horn showing homogeneity of the tissue where there are some cells that correspond to the bodies of previous motor neurons.


Marrow. Previous HEx400.
parenchyma of the anterior horn of the spinal cord showing motor neuron CURP composed of a granular cytoplasm with numerous clusters called Nissl bodies.

Marrow. Previous HEx400.
Another detail of the parenchyma of the anterior horn of the spinal cord showing motoneurons bodies composed of a granular cytoplasm with numerous clusters called Nissl bodies. We can observe the glial support their nuclei of oligodendrocytes.



Spinal cord. HEX100.
Details medullary parenchyma in the center where we observe the presence or ependymal cells lining the spinal canal. You can see the consistency of the tissue and the presence of numerous blood vessels, some of them dilated.


spinal ganglion. HEX400.
enlarged image taken from the back of the bone and the and external surface area extrameníngea. Septation is observed in the lymph node parenchyma and the presence of ganglion cells with vacuolated cytoplasm and basophilic nuclei containing well-defined and fine granulations.
spinal ganglion. HEX400.
image taken from the back of the bone and the external surface area and extrameníngea. The meninges are in the bottom right of the image.
capsular linings are even observe that perfectly delimited.


Marrow. Previous HEx400.
Any other detail of the parenchyma of the anterior horn of the spinal cord showing the bodies of two motoneurons consist of a granular cytoplasm with numerous conglomerates (Nissl bodies described above).
We can observe the abundant glial support their nuclei of oligodendrocytes.


Spinal HEX400.
ependymal cells.
These cells are also part of the cellular component of glia are cuboid cell cilia in the image can not be appreciated.
These cells contain the nuclei slightly basophilic.
