Axon, Biology

Assignment Help:
Axon:
  1. Axon is a projection from the cell body.
  2. Each neuron has only one axon.
  3. Unlike dendrites, axons are very long and are usually unbranched structures.
  4. The axon is generally called as nerve fibre.
  5. The cytoplasm of the axon is covered with a plasma membrane.
  6. Nissil granules are absent in axon.
  7. At the end, the axon gives out several branches that end in NERVE TERMINAL.
  8. Each of these nerve terminal makes contact with the dendrites or cell body or even axons of another neuron.
  9. Some of axons also make contact with the cells in the effector organs such as muscles or glands. This site is called a SYNAPSE.
  10. In some neurons, axons are covered by a sheath called MYELIN SHEATH. At regular intervals, the myelin sheath leaves small gaps called NODES OF RANVIER.
