Across
  1. 7. The small gap between the presynaptic and postsynaptic neurons, where neurotransmitters are released and received.
  2. 8. Gaps in the myelin sheath where the axon is exposed; important for conduction of nerve impulses
  3. 11. The neuron that receives the signal
  4. 13. Specialized cells in the peripheral nervous system that make the myelin sheath around axons
  5. 15. Small structures at the end of the axon that release neurotransmitters to communicate with the next neuron or target cell
  6. 16. aka Efferent Neurons Neurons that carry signals from the central nervous system (CNS) to muscles or glands, enabling the execution of motor responses.
  7. 17. A long, slender extension of the neuron that carries signals away from the cell body to transmit them to other neurons or target cells
  8. 19. Rapid, involuntary, and automatic response to a stimulus, signal does not go up to the brain. Fast.
Down
  1. 1. aka Association Neurons Neurons found within the central nervous system (CNS) that act as intermediaries, connecting sensory and motor neurons. Think and decide.
  2. 2. A more complex and conscious response to a stimulus, involving higher brain centers, cognitive processing, and often influenced by learning and experience.
  3. 3. aka Afferent Neurons Neurons that transmit sensory information from sensory organs (such as the eyes, ears, skin) to the central nervous system (CNS),
  4. 4. The neuron that sends the signal, releasing neurotransmitters into the synapse.
  5. 5. Branch-like extensions from the cell body that receive signals from other neurons and transmit them toward the cell body
  6. 6. The junction between the axon terminal of one neuron and the dendrites or cell body of another, where communication occurs
  7. 9. The main part of the neuron that contains the nucleus and other organelles, responsible for maintaining the cell's metabolic functions
  8. 10. Sheath A fatty insulating layer surrounding the axon, which speeds up the transmission of electrical signals
  9. 12. Chemical messengers released by neurons into the synapse to transmit signals from one neuron to another
  10. 14. A brief electrical impulse or spike that travels along the axon, allowing for the long-distance transmission of signals.
  11. 18. A specialized cell in the nervous system that transmits information through electrical and chemical signals
