Neurons

• What is the primary function of neurons?

  To enable communication within the nervous system
• What do dendrites do in a neuron?

  They carry information towards the cell body
• What is the role of the cell body in a neuron?

  It contains the genetic material
• How do axons function in neurons?

  They carry messages away from the cell body
• What is the myelin sheath's function?

  To increase the speed of nerve transmission
• What are terminal boutons?

  They make synaptic connections with other cells
• What type of neurons carry messages from receptors to the CNS?

  Sensory neurons
• What is the function of motor neurons?

  To carry motor commands from the CNS
• Where are relay neurons found?

  In the brain and spinal cord
• How do sensory neurons function when touching a hot pan?

  They send heat information to the brain
• What role do relay neurons play in the reflex action of dropping a hot pan?

  They analyze the sensation and decide actions
• What happens when Pavel touches the hot handle of the pan?

  Sensory neurons send heat information to the brain
• What is the structure of a sensory neuron?

  Long dendrites and short axon
• How do motor neurons differ from sensory neurons?

  Motor neurons carry commands to effectors
• What type of neuron carries impulses between other neurons?

  Relay neuron
• What is the function of the axon in a neuron?

  To carry messages away from the cell body
• What is the role of neurotransmitters at axon terminals?

  To transmit signals to other neurons
• What are the types of neurons and their functions?

  • Sensory Neurons: Carry impulses towards the CNS
  • Motor Neurons: Carry commands from the CNS to effectors
  • Relay Neurons: Interconnect sensory and motor pathways
• Describe the structure and function of a neuron.

  • Cell body (soma): Contains genetic material
  • Dendrites: Extend from the cell body, receive information
  • Axon: Carries messages away from the cell body
  • Myelin sheath: Increases speed of transmission
  • Terminal boutons: Make synaptic connections with other cells
• Which neuron carries electrical impulses towards the brain?

  Sensory neuron
• What is the function of sensory neurons in Pavel's situation?

  To sense heat and send information to the brain
• What do relay neurons do in the context of Pavel dropping the pan?

  They analyze the sensation and decide actions
• What type of neuron is involved in analyzing sensations?

  Relay neuron
• How do sensory and motor neurons work together?

  Sensory neurons send information to motor neurons
• What is the role of the nucleus in a neuron?

  Contains the genetic material
• What is the significance of myelination in neurons?

  It speeds up nerve transmission
• How do the structures of sensory and motor neurons differ?

  Sensory neurons have long dendrites; motor neurons have long axons
• What happens at the terminal boutons of a neuron?

  They release neurotransmitters to transmit signals
