__ receive signals from other cells and the __ carries the neurons message to other body cells.
glial cells; neurons
dendrites; axon
neurons; glial cells
axon; dendrites

Explanation:

1. Glial cells support and maintain neurons. Motor neurons transmit signals for muscle - movement, sensory neurons detect stimuli, and dendrites are part of a neuron for signal - reception. So, neurons are held in place and supported by glial cells.
2. Dendrites receive signals from other cells and the axon carries the neuron's message to other body cells. Glial cells are for support, not signal - reception or transmission in the way described.

Answer:

1. B. glial cells
2. B. dendrites; axon
