Nervous System
Across
- 3. The nervous tissue that conducts messages between the brain and the peripheral body parts.
- 5. is the division of the nervous system containing all the nerves that lie outside of the central nervous system
- 6. The part of the nervous system consisting of the brain and spinal cord.
- 7. The white fatty membrane that protects the neuron.
- 8. the region of the brain that controls involuntary activities.
- 11. part of the neuron that receives nerve impulses and transmits them toward the cell body.
- 12. variety of glial cells that keep peripheral nerve fibers alive.
- 14. allow neurons to transmit electrical and chemical signals to other cells.
- 15. An electrochemical pulse that moves along the membrane of a neuron.
- 16. is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord
- 17. are attached to bones by tendons, and they produce all the movements of body parts in relation to each other.
- 20. The part of the brain containing motor and sensory centers: controls voluntary movement.
Down
- 1. Part of the brain that monitors and adjusts body activities.
- 2. triggers the release of neurotransmitters from the axon into the synapse.
- 4. The chemicals responsible for extending the nerve impulse from one cell to the next one.
- 9. Part of the brain, relay center between spinal cord and brain, reflex center.
- 10. for example sweating as a response to an increase in temperature (involuntary actions).
- 13. The junction between the axon and dendrite.
- 18. The series of neurons that produces a single reaction in response to a stimulus.
- 19. the functional unit of the nervous system. The cell receives and distributes nerve impulses.
