Nervous System and Neurons

The central nervous system is comprised of all the neurons in the brain and the ____.

• Spinal Cord
• Cerebellum
• Medulla
• Pons

The myelin sheath

• a nueroglia makes the signal travel faster

• protects the neuron
• carries the signal away from the cell body
• carries the signal to the cell body

Reorder how electrical impulses travel down the neuron. (1 is the begininng)

• Axon Terminal

• Dendrite

• Soma

• Axon

• Myelin Sheath

What is the difference between a neuron and a glial cell?

• Neurons are responsible for sending and receiving signals, while glial cells provide support and protection for neurons

• Neurons are found in the brain, while glial cells are found in the spinal cord

• Neurons are made up of glial cells, while glial cells are made up of neurons

• Neurons contain myelinated axons, while glial cells contain cell bodies and dendrites

What is the difference between an axon and a dendrite in a neuron?

• Axons transmit output signals, while dendrites receive input signals

• Axons and dendrites both transmit output signals

• Axons and dendrites both receive input signals

• Axons receive input signals, while dendrites transmit output signals
