6.3.1 Types of Neurons

• What are neurons specialized cells for?

  Transmitting signals
• The cell body of a neuron is also called the soma
• Match the key components of a neuron with their primary function:

  Cell Body (Soma) ↔️ Maintains the neuron's life processes

  Dendrites ↔️ Receive signals from other neurons

  Axon ↔️ Transmits signals to other neurons

  Axon Terminals ↔️ Pass signals via synapses
• Order the steps in the transmission of a signal through the nervous system:

  1️⃣ Sensory receptors detect a stimulus

  2️⃣ Sensory neurons transmit signals to the CNS

  3️⃣ Interneurons within the CNS process the signal

  4️⃣ Motor neurons transmit commands to muscles

  5️⃣ Muscles or glands respond to the signal
• Where are interneurons located?

  Central nervous system
• Motor neurons transmit signals from the CNS to muscles and glands
• Sensory neurons transmit signals from the CNS to muscles and glands.

  False
• What is one main function of glial cells?

  Support and protection
• Oligodendrocytes form myelin sheaths around axons in the CNS
• Match the type of glial cell with its function:

  Astrocytes ↔️ Maintain extracellular environment

  Oligodendrocytes ↔️ Form myelin in the CNS

  Microglia ↔️ Immune defense in the CNS

  Schwann Cells ↔️ Form myelin in the PNS
