2.2.1 Neurone
Structure of a neurone

  1. The basic unit of the nervous system is neurone.
  2. The function of neurone is to carry impulses.
  3. Each part of s neurone plays an important role in the transmission of nervous impulses.

Neurone Part
Cell body
Controls all activities of the neurone
Transmits impulses towards a cell body
Receives impulse from other neurone and transmits them to cell body
Transmits impulses out of cell body
Myelin sheath
·        Speed up the transmission of impulses
·        Insulator that prevents the leakage of impulses
