Nervous system

Label the image of the neuron with the correct term

- Node of Ranvier                                                                   - Axon

- Schwann Cell                                                                       - Axon Terminals

- Myelin Sheath                                                                     - Dendrites

- Cell Body

 

Which of the following best describes a process involved in the nervous system receiving internal signals?

Electrical signals are passed from dendrites to axons in sensory neurons through the peripheral nervous system.

Motor neurons carry information from muscle cells to the central nervous system for processing.

Neurotransmitters pass information across synapses between sensory neurons on the way to the central nervous system.

Sensory neurons transmit information from the central nervous system to the peripheral nervous system.
