neurotransmission

• neurotransmission


  travel of impulse along neurone to another neurone
• spinal cord


  made up of nerves

  connects brain to rest of nervous system
• receptor cells


  detect stimuli change in environment
• motor neurone

  nerve cell carry impulses from CNS to muscles

  dendrites join onto cell body, long axon
• relay neurone


  never cell in CNS makes decisions

  dendrites join onto cell body, short axon
• sensory neurone

  nerve cell carries impulses from sense organ to cns

  long axon and dendron
• dendron 


  nerve fibres transmit impulses to cell body
• dendrites


  end branches of dendrons

  connect to receptor cell/neurone
• dendron and axon


  long part of neurone

  carry impulse to cell -dendron

  impulse away -axon
