Across
- 2. A fatty, insulating layer that wraps around nerve cells in the brain and spinal cord
- 4. Process of a neuron conduct impulses away from the cell body. The terminal branches of an _________ convert electrical impulses into chemical messages called neurotransmitters. Released into synapses to relay messages to other neurons or muscle cells.
- 6. produce myelin, which forms protective sheaths around nerve fibers
- 9. These are the gaps between neurons that serve as a site of transmission for electrical impulses
- 10. neurons These neurons synapse with muscles at the neuromuscular junction and directly control muscle contraction
- 11. Gaps in the myelin sheath that insulates the axons of nerves
Down
- 1. Also known as soma, this structure of the neuron connects with other parts of the neuron
- 3. Also known as association neurons, these neurons reside completely within the central nervous system, which is located in the brain and spinal cord
- 5. The bulbous endpoints of a neuron's axon that store and release neurotransmitters
- 7. neurons These neurons help us feel and explore the world around us, including major senses such as touch and pain
- 8. These branched extensions of a neuron receive electrical signals from other neurons and pass them to the cell body.
