BIO426 Nervous System
Across
- 5. Electrical state of the cell membrane when the inside of the cell becomes more positive or less negative
- 6. Structure in arthropods that is equivalent to the vertebrates spinal cord
- 8. Neurotransmitter that stimulates muscle contraction
- 10. Electrical state of the cell membrane at rest when the inside is negative and the outside is positive
- 11. Most common site on a neuron of input from other neurons
- 13. Type of nervous system immune cell in the CNS
- 16. Type of myelinating cell in the PNS
- 18. Part of a neuron that houses the cell nucleus and conducts electrical signals to the axon
Down
- 1. Pain receptors
- 2. Ion that would cause hyperpolarization if entering into a resting cell
- 3. Bundle of neurons that send signals to places in the bodies periphery
- 4. Site on a neuron where an action potential is initiated
- 7. Type of neurotoxin that inhibits voltage-gated Na+ channels and may be released from the Japanese pufferfish
- 9. Neurotransmitter that is released during the fight or flight response
- 12. Type of neuron with dense dendrites (i.e. motor neuron)
- 14. Type of nervous system cell associate with blood capillaries in the CNS
- 15. Ion necessary for exocytosis of synaptic vesicles
- 17. Place where a neuron passes a signal on to its effector (i.e. another neuron)
