====== NEURO CYTOLOGY  ======

  * Each nerve fiber has 
     * cell body 
     * axon 
     * Perikaryon 


  * neurons based on  
    * cognitive neurons  
    * vegetative neurons 

**nerve fibre names based on sequence** 

  * first order , second order , third order : mainly used for sensory neurons 
  * preganglionic , postganglionic : autonomic nervous system 

**nerve fibre names based on location**

  * upper , lower motor neurons 
 
**nerve fibre names based on connection to and from**

  * almost all nerves are named on the basis of origin to termination that is from nuclei to nuclei. 
  * sensory neurons towards the brain 
  * motor neurons away from the brain 

**according to the length of axon **

  * golgi type 1 - long axons and short dendrites eg., pyramidal cells of cerebral cortex , purkinje cells , anterior horn cells 
  * golgi type 2 - short axons 


**according to number of processes **

  * unipolar 
  * bipolar 
  * multipolar 

**according to shape of cells**

  * stellate 
  * basket
  * fusiform 
  * pyramidal
