Abstract:
Unusual glial cells not related with perikarya or fibres were observed with the electron microscope in dorsal root spinal ganglia. These interstitial cells were very electron dense, with big and irregularly shaped nucleus and scanty organelles. They occurred immersed in the endoneurial space tissue, with no basal lamina and presented no contacts with other cells. In addition to these interstitial cells present both in kittens and adult cats, younger kitten sensory ganglia contained refringent glial cells.

Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...
