Neurons

• What is the main function of neurons?

  To transmit electrical impulses
• Which type of neuron carries impulses from receptors to the spinal cord or brain?

  Sensory neuron
• What is the role of the motor neuron?

  To carry impulses from the spinal cord to muscles
• What is the function of the myelin sheath?

  To increase the speed of electrical impulses
• What is the synapse?

  The gap between two neurons where neurotransmitters are released
• What type of cell releases neurotransmitters at the synapse?

  Axon terminal of the neuron
• Which part of the neuron receives electrical impulses?

  Dendrites
• What happens when a neuron is stimulated to its threshold?

  It generates an action potential that travels along the axon
• What is the function of the axon?

  To transmit electrical impulses away from the cell body
• Which part of the neuron is responsible for the electrical impulse traveling to the next neuron or muscle?

  Axon
