Study Notes

Neuron Structure and Function

  • The identifying point between a neuron and other cells is the presence of neurofibrils.
  • Golgi Bodies are mainly located near the cell body (soma) of a neuron.
  • Neurofibrils provide mechanical support and maintain the shape of a neuron.
  • Nissl granules, also known as rough endoplasmic reticulum, are responsible for protein synthesis in a neuron.
  • Mitochondria are located throughout the neuron, including the axon and terminals, and provide energy for neuronal activities.
  • Nissl granules are chemically rich in RNA and are the site of protein synthesis in a neuron.
  • Mitochondria function to generate energy for a neuron through cellular respiration.
  • The unique feature that distinguishes neurons from other cells is the presence of neurofibrils.
