    Cards (67)

    • What is a neuron?
      Nerve cell
    • The major parts of a neuron include the cell body, dendrites, and axon
    • The cell body of a neuron contains the nucleus and is responsible for the neuron's general functions.
    • What is the primary function of dendrites in a neuron?
      Receive signals
    • The axon of a neuron conducts nerve impulses away from the cell body to other neurons or target cells
    • Neurons transmit both electrical and chemical signals throughout the nervous system.
    • What is the role of the nucleus in the cell body of a neuron?
      General functioning
    • The axon is a long, slender fiber that conducts nerve impulses away from the cell body
    • What structures are located at the end of the axon to transmit signals to other neurons?
      Synaptic terminals
    • The cell body of a neuron is responsible for receiving signals from other neurons.
      False
    • What do dendrites transmit to the cell body of a neuron?
      Signals
    • The axon of a neuron conducts nerve impulses away from the cell body
    • Where are synaptic terminals located in a neuron?
      End of axon
    • The axon transmits signals to other neurons through synaptic terminals.
    • The cell body of a neuron contains the nucleus
    • What is the function of the axon in a neuron?
      Conduct nerve impulses
    • Match the neuron component with its function:
      Dendrites ↔️ Receive signals
      Axon ↔️ Conduct impulses
    • What is the primary function of dendrites in a neuron?
      Receive signals
    • The axon of a neuron conducts nerve impulses
    • A neuron is the fundamental unit of the nervous system.
    • Match the neuron component with its function:
      Cell Body (Soma) ↔️ Supports neuron functions
      Dendrites ↔️ Receives signals
      Axon ↔️ Conducts impulses
      Synaptic Terminals ↔️ Transmits signals
    • Where are synaptic terminals located in a neuron?
      End of axon
    • The axon is a long fiber that conducts nerve impulses away from the cell body
    • Synaptic terminals transmit signals to other neurons or target cells.
    • What is the main function of the cell body in a neuron?
      Integrate signals
    • The axon ensures signals are transmitted efficiently over long distances
    • Synaptic terminals use neurotransmitters to transmit signals.
    • What is the myelin sheath composed of?
      Lipids and proteins
    • The myelin sheath increases nerve impulse transmission through saltatory conduction
    • Which cells form the myelin sheath in the PNS?
      Schwann cells
    • Nodes of Ranvier are essential for saltatory conduction.
    • Nodes of Ranvier expose the axon membrane, allowing depolarization
    • How many main parts does a neuron have?
      Four
    • Match the neuron component with its function:
      Cell Body (Soma) ↔️ Basic cell processes
      Dendrites ↔️ Receive signals
      Axon ↔️ Conduct impulses
      Synaptic Terminals ↔️ Transmit signals
    • A neuron transmits both electrical and chemical signals.
    • What is a neuron?
      A nerve cell
    • The cell body, also known as the soma, contains the nucleus and manages neuron functions.
    • The cell body manages the neuron's metabolism.
    • What is the function of dendrites in a neuron?
      Receive signals
    • The axon conducts nerve impulses away from the cell body.
