Which of the following elements are visible in the neurons by light microscopic observation

The nonmyelinated nerve fibers consist of

The myelinated nerve fibers consist of

The parts of the neuron are: -[blank_start]perikaryon[blank_end] ([blank_start]body[blank_end]) -[blank_start]axon[blank_end] -[blank_start]dendrites[blank_end]

Depending on the shpae of their bodies (perikaryons) the neurons are: a) [blank_start]star-shaped[blank_end] ([blank_start]multipolar[blank_end]) b)[blank_start]pyramidal[blank_end] c)[blank_start]pear-like[blank_end] d)[blank_start]spherical[blank_end] or [blank_start]spindle[blank_end] shaped

Depending on the number of their branches the neurons are; a)[blank_start]unipolar[blank_end] b)[blank_start]pseudounipolar[blank_end] c)[blank_start]bipolar[blank_end] d)[blank_start]multipolar[blank_end]

Depending on their functions the neurons are: a) [blank_start]motor[blank_end] ([blank_start]efferent[blank_end]) b)[blank_start]sensory[blank_end] ([blank_start]afferent[blank_end]) c)[blank_start]associative[blank_end] d) [blank_start]neuroendocrine[blank_end]

The central type of neuroglial cells are: a) [blank_start]astrocytes[blank_end] b)[blank_start]oligodendricites[blank_end] c)[blank_start]ependymal[blank_end] d)[blank_start]microalgia[blank_end]

By light microscopic observation of the spinal cord ont ransverse sections stained with toluidinblue, multipolar neurons with cytoplasm filled with blue granules in the anterior horns are observed. What is the name fo these structures and the appearence of which organelle are they? [blank_start]Nissl Substance[blank_end] ([blank_start]rough[blank_end]-surfaced [blank_start]endoplasmic reticulum[blank_end] )

Under electron microscope, a transverse section of cylindrical in shape structure with dark and light lines arranged in concentric manner is observed. Peripherally, a part of cytoplasm with mitochondria and nucleus is visible. What is the name of the described structure? [blank_start]Myelinated Nerve fibers[blank_end]

Under light microscope, on sections from cerebrum stained with AuCl2 star-shaped neurons with numerous long non-branching processes localised in the white matter are observed. Some of the processes attach to the blood vessels walls. What is the name of these cells and what is their function? [blank_start]Fibrous astrocytes[blank_end]-

Under light microscope, on sections stained with OsO4 bundles of black coloured fiber-like structures appear. There are gaps in their outer sheath and it is seen to be an incomplete or interuppted cylinder. Radial clefts or fissures, extending through the thickness of the sheath are also visible. What is the name of the described structures? [blank_start]Myelinated nerve fibers[blank_end]
