Neurophysiology- Neurones

    Cards (19)

    • What role does ionic balance play in neuronal cells?
      It maintains excitability and generates potentials
    • What cellular mechanisms are involved in synaptic transmission?
      Release of neurotransmitters between neurons
    • What is the hierarchical process of neuronal signaling?
      From single cell to neuronal networks
    • What are the two main types of neuronal cells?
      • Neurones: conduct impulses and process information
      • Glia: support functions and immune regulation
    • What is the basic unit of structure and function in the nervous system?
      Neurones
    • What do neurones do with environmental changes?
      They sense and communicate changes
    • What is the energy requirement of neurones?
      High energy usage, needs glucose and oxygen
    • What are dendrites responsible for?
      Receiving messages from other neurones
    • What do axons provide for neurones?
      Output through a single extension
    • How can neurones be classified?
      By function, location, morphology, neurotransmitter
    • What do motor neurones do?
      Carry impulses away from the brain
    • What do sensory neurones do?
      Carry impulses to the brain and spinal cord
    • What is the function of relay neurones?
      Process incoming impulses and pass them on
    • What is membrane excitability in neurophysiology?
      • Ability of neuronal membranes to generate action potentials
      • Influenced by ionic balance and membrane potential
    • What are the types of synaptic transmission?
      • Electrical synapse: direct current flow
      • Chemical synapse: neurotransmitter release
    • What is the purpose of an electroencephalogram (EEG)?
      To record neuronal activity in networks
    • How are sub-dermal electrodes used in EEG?
      Placed at specific locations on the skull
    • What does local field potential (LFP) measure?
      The underlying ionic environment and activity
    • What are the recommended resources for further reading?
      • Cunningham et al. Textbook of Veterinary Physiology, Chapter 15
      • Lifelines Neuro website
      • American Kennel Club Epilepsy Resource
