Across
- 5. The branching extensions of a neuron that receive signals from other neurons and transmit them to the cell body.
- 6. cleft The tiny space between the presynaptic neuron and the postsynaptic neuron where neurotransmitters are released.
- 7. Chemical substances that transmit signals across a synapse from one neuron to another. Examples include dopamine and serotonin.
- 10. neuron A type of neuron that connects sensory and motor neurons within the central nervous system, playing a role in reflexes and signal processing.
- 11. neuron A type of neuron that carries information from sensory receptors to the central nervous system.
- 14. A protein molecule located on the surface of a cell that binds to specific neurotransmitters, triggering a response.
- 15. The long, threadlike part of a neuron that transmits electrical impulses away from the cell body to other neurons, muscles, or glands.
Down
- 1. potential The electrical signal that travels along the axon of a neuron, triggered when a neuron is activated.
- 2. neuron A type of neuron that transmits signals from the central nervous system to muscles or glands, causing movement or responses.
- 3. The small gap between two neurons where neurotransmitters are released to transmit signals from one neuron to the next.
- 4. Refers to signals or neurotransmitters that decrease the likelihood of a neuron firing an action potential.
- 8. Refers to signals or neurotransmitters that increase the likelihood of a neuron firing an action potential.
- 9. A fatty substance that covers and insulates axons, increasing the speed at which electrical impulses are transmitted.
- 12. A muscle or gland that responds to a signal from a motor neuron by contracting or releasing a substance.
- 13. pathway A series of connected neurons that transmit signals between different areas of the nervous system.
