Lesson 358 of 1524
The Nervous System
The nervous system is made up of neurons and glia.
Practice this chapterThe nervous system is made up of neurons and glia. Most neurons contain dendrites, which receive these signals, and axons that send signals to other neurons or tissues.
Glia are non-neuronal cells in the nervous system that support neuronal development and signaling. Neurons are specialized cells that are capable of sending electrical as well as chemical signals.
nervous system — made up of neurons and glia. axon — tube-like structure that propagates a signal from a neuron’s cell body to axon terminals. dendrite — structure that extends away from the cell body to receive messages from other neurons. neuron — specialized cell that can receive and transmit electrical and chemical signals.
Worked example
What does “nervous system” mean in The Nervous System?
- 1Use the wording this chapter gives for nervous system.
- 2The book says: made up of neurons and glia.
- 3Do not use the meaning of axon. That term means tube-like structure that propagates a signal from a neuron’s cell body to axon terminals.
Result: made up of neurons and glia
Why. That is the meaning this chapter gives for nervous system.
Do not swap nervous system and axon. nervous system means made up of neurons and glia. axon means tube-like structure that propagates a signal from a neuron’s cell body to axon terminals.
