Q

Neuron

A
  • Is the structural unit of the nervous system.
  • It’s responsiveness to a stimulus
  • ability to propagate electrical signal
  • release of neurotransmitter in response to conductive activity
  • cell can live throughout person’s lifetime
  • after fetal development, mitotic activity is lost in most neurons
