Tissues > Neuron
|
|
- neurons are considered as the longest cells of the body.
- Each neuron arises in the embryo, from a single neuroblast cell. Its main cell body is called Cyton, Perikaryon or Soma.
- Cytons of most neurons occur in the Grey matter of central nervous system particularly in brain. A few cytons are present outside the CNS also in clusters, called ganglia.
- The cyton contains neuroplasm, a prominent spherical nucleus, mitochondria, golgi bodies, ER, ribosomes, lysosomes, fat globules, pigment granules etc. Besides the presence of Nissl Bodies and Neurofibrils are characteristic of all neurons. Nissl bodies are comparatively large masses of ribosomes and RER. Neurons are without centrosome. Once fully formed, these never divide and remain in the G0 phase of interphase throughout the life. These, however, grow to a larger size with growth of the body.
