| Popis: | The ventral horn cell of the lumbar cord of the albino rat was examined with the electron microscope. The tissue was fixed with osmium tetroxide or a formalinosmium tetroxide sequence, dehydrated and embedded in Epon 812. The nuclear envelope contains numerous pores which are spanned by diaphragms. Nuclear indentations or crypts are seen often, and are considered normal structures. Mitochondria with various arrangements of cristae are described. These include tubular cristae, simple dilated cristae, dilated cristae enclosing vesicles, and sacs which partially contain double membrane limited bodies. The Golgi apparatus is scattered throughout the cytoplasm. The apparatus is seen near the nucleus more frequently than peripherally. Single membrane limited bodies such as multivesicular bodies and electron dense bodies are described. Granular endoplasmic reticulum exists as orderly stacks and as haphazardly scattered cisterns. Serial sections demonstrate that the haphazardly scattered cisterns are extensively interconnected. |
