Question

Which one of the following pairs of structure distinguishes a nerve cell from other types of cell?

• A. Flagellum and medullary sheath
• B. Nucleus and mitochondria
• C. Perikaryon and dendrites
• D. Vacuoles and fibres

Answer 1

The correct option is C Perikaryon and dendrites

• The structural difference between a neuron and other kinds of cell include the perikaryon and dendrites.
  
• The cell body of a neuron, known as perikaryon, has a large and round nucleus. Nissil granules are present in its cytoplasm forming the characteristic feature.
  
• While dendrites are branched thread like structure arising from cyton which functions to receive impulses from sensory system and transfer it in form of electrical impulses to other neurons via the Axon.
  

So, the correct option is 'Perikaryon and Dendrites'.
