Neurons

  • What are dendrites?
    Dendrites are the branches of Soma. They receive the signals and send them.
  • What is the soma?
    Hold the nucleus and organelles (cell body)
  • what are axon terminals?
    Transmitters of nerves
  • What can and cannot be in a neuron
    Neurons can only have one soma and no more than one Axon. They can have thousands of dendrites and axon terminals.
  • Dendrites are the input region
  • Axons transmit information
    • Some actions have myelin sheats by particular glial cells.
    • Conducting regions of neurons
  • Axons or initial segments (integration region) collect into neurons and receives input from other neurons before determining if it is worth it or not and if they should relay along the conducting region.
  • Skelton of the neuron extends the cell body, and axon to the terminal and provides neuron structure.
  • Axon terminal are specialised regions: synapses (output regions of neurons)
  • Spines 1 protrusions that extend dendrties
  • Thin spines = learning spines
  • Large mushroom spins "memory spines"
  • Dendrite spines are all in different shape a sizes depending on what spine it is
  • Spines = extended dendrites
  • Spines of dendrites
    Excitatory input is provided by other neurons
  • Spinesof dendtrites 

    chemical flows into cell when activated
  • Cytoskeletons have micro and neuro filaments to ensure the rigidity of the neuron. It also has microtubules for transport.
  • The components of a cytoskeleton extent throughout the neuron from the cell body through the axon to the terminal. Giving the neuron structure.
  • Axon terminals are specialised regions called synapses.
  • The synapses contact other cells without touch by sending chemical transmitters between neurons. They are the output regions of neurons.
  • Axon terminals = Synapases
