Many multipolar neurons (red arrows) could be observed in the ventral horn of grey matter.

White matter contains many nerve fibers.

Multipolar neurons (MN) has a large, pale-stain nuclei with a prominent nucleous and abundant Nissl bodies (black arrows) in the cytoplasm.

Nissl bodies would not extend into axon hillock or axon (black triangle).

A multipolar neuron (MN) has a large, pale-stain nuclei and abundant rER (stars; Nissl bodies in LM) in the cytoplasm.

The photograph also shows that oligodendrocytes (OD) surround MN.

Abundant rER (stars) are  in the cytoplasm of multipolar neuron (MN) which is surrounded by oligodendrocytes (OD).

Enlarged view of the cytoplasm of multipolar neuron (MN) shows that abundant rER clusters to form Nissl bodies under light microscope.

Many mitochondria (M) are also found in the MN.

The cortex of cerebellum is composed of three layers: Molecular layer, Purkinje cell layer, and granule cell layer.

Red arrows indicate Purkinje cell in the Purkinje cell layer and green arrows point granule cells in the granule cell layer.

Scale bar=10 µm.

Red arrows indicate Purkinje cell in the Purkinje cell layer and green arrows point granule cells in the granule cell layer.

Purkinje cell (PC) has a large sized , euchromatic nucleus (N) and a well-defined nucleolus ( white arrow).

Granule cell (GC) has less cytoplasm.

Purkinje cell (PC) has a large sized , euchromatic nucleus (N), well-defined nucleolus ( black arrow) and many mitochondria.

Granule cell (GC) has less cytoplasm.

Parallel fibers  could be observed in molecular layer.

This photography shows part of cerebral cortex. Several pyramidal cells (red arrows) with prominent nucleolus could be observed and their apical dendrites (black arrowheads) project toward the cortex surface.

A pyramidal cell with prominent nucleolus (blue arrows) could be observed and one of its process (between yellow dash line) is shown in the photography. Many myelinated processes (red stars) are nearby the pyramidal cell .

The process of a pyramidal cell (between yellow dash line) is shown in the photography and many mitochondria (M) and microtubules (blue arrows) are inside the process. In the cell body, there are abundant of rough endoplasmic reticulum (rER, black arrows). Many myelinated processes (red stars) are nearby the pyramidal cell .

Enlarged picture of cell body and process of the pyramidal cell is shown. Many mitochondria (M) and microtubules (blue arrows) are inside the process. In the cell body, there are abundant of rough endoplasmic reticulum (rER, black arrows)

Many mitochondria (M) and rough endoplasmic reticulum (rER, black arrows) are inside the cell body of the pyramidal cell. In this picture, Golgi apparatus (G) and clear two-layer nuclear membranes (purple arrows) are demonstrated.

Nearby the pyramidal cell, two synapses (red dashed circle) are found in this photo. Mant mitochondria (M), microtubules (blue arrows), and free ribosomes (Rib) are inside the process.

Dorsal root ganglion contains pseudounipolar sensory neurons. The cell bodies of the sensory neurons have centrally located nuclei (N, red arrows) which are large, pale-staining and have intensely staining nucleoli (black arrows). These neurons are typically arranged as closely packed clusters. There are bundles of nerve fibers (NF, yellow dashed lines) between and around the cell clusters.

Dorsal root ganglion neurons have centrally located nuclei (N, red arrows) which are large, pale-staining and have intensely staining nucleoli. Dorsal root ganglion neurons are surrounded by satellite cells (SC，blue arrows) Myelinated nerve fibers (NF) could be observed between neurons.

Dorsal root ganglion neurons have centrally-located nuclei (N) which have intensely staining nucleoli (black arrow), and are surrounded by satellite cells (SC，blue arrows). Myelinated nerve fibers (NF) could be observed between neurons. Capillaries (C) are also shown in the picture.

This photography shows a dorsal root ganglion neuron and its centrally-located nuclei (N) which nucleolus is not shown. Typical features of a neuron that plenty of rough endoplasmic reticulum (rER) and mitochondria (M, yellow arrows) are also demonstrated. A satellite cell (SC，blue arrow) is surround the neuron. Myelinated nerve fiber (res star) is nearby the neuron.
