  1. 2. Cells in the nervous system that are non-neural and don't send impulses. Rather they aid in protecting neurons, maintaining homeostasis, and form myelin
  2. 3. The neurons that connect the spinal motor and sensory neurons. They form circuits often to communicate with each other
  3. 5. The ending branches of the axon that form synaptic relationships to whatever the neural impulse is going to ( including other neurons, glands, or muscles )
  4. 7. A drug or chemical that blocks an action such as an agonist
  5. 9. A drug or chemical that is similar to a neurotransmitter but binds to a receptor which creates an effect in the neuron
  6. 11. A system that controls unconscious bodily functions such as digestion, heartbeat, and respiratory rate
  7. 13. A part of the neuron that bring neural impulses from the cell to the terminal branches that send the message to the other neurons
  8. 15. A system that regulates hormones through the release of hormones from glands into the bloodstream
  9. 17. Sensory neurons that use sensory stimuli to carry nerve impulses to the brain and central nervous system
  10. 18. The part of the neuron that forms a synaptic connection in order to receive neural messages from other cells
  11. 19. A substance created in glands that stimulates action to regulate different bodily functions
  12. 20. Motor neurons that take neural impulses from the spinal cord and brain ( CNS ) and towards muscles to invoke movement
Down
  1. 1. A substance released from nerves when a nerve impulse is triggered that travels through neurons and uses synapses to move the impulse to other neurons and eventually to the final location
  2. 4. A bundle of fibers that sends sensations from muscles to the brain
  3. 6. The study of behavior and animals through the lens of biological psychology
  4. 8. A system that controls bodily actions such as movement, thoughts, speech, feeling, and memory. This system consists of the brain and spinal cord
  5. 10. A layer that surrounds the nerve in order for neural impulses to quickly transmit through the cell
  6. 12. An electrical stimulus that depolarizes a current in order for positively charged ions to go into the cell and negatively charged ions out
  7. 14. The scientific study of the nervous system including the brain structure and function
  8. 16. A cell in the nervous system that carries impulses from the muscles to the brain and spinal cord and vise versa
