Nervous System Physiology
Across
- 3. Includes the brain and spinal cord of dorsal body cavity
- 10. activation of effector organs (muscles and glands) produces a response
- 11. Branched cells that wrap neurons of the CNS
- 12. Line the central cavities of the brain and spinal column Form a permeable barrier between cerebrospinal fluid in cavities and tissue of the brain and spinal cord
- 13. Processing and interpretation of sensory input
- 14. “Fight or Flight”…or Freeze
- 15. Consists mainly of nerves that extend from the brain and spinal cord
- 17. Surround and support neuron cell bodies in PNS
- 18. has two divisions: Somatic Nervous System & Autonomic Nervous System
- 19. Small, ovoid cells with thorny processes that touch and monitor neurons Migrate toward injured neurons
Down
- 1. Somatic motor nerve fibers conduct impulses from CNS to skeletal muscle Voluntary,conscious control of skeletal muscles
- 2. Surround all peripheral nerve fibers and form myelin sheaths in thicker nerve fibers
- 4. Visceral sensory fibers convey impulses from _______ to the CNS
- 5. Information gathered by sensory receptors about internal and external changes
- 6. Consists of visceral motor nerve fibers Involuntary control of smooth muscle, cardiac muscle, and glands
- 7. excitable cells that transmit electrical signals
- 8. “Rest and Digest”
- 9. small cells that surround, support, and/or wrap delicate neurons
- 16. Somatic sensory fibers convey impulses from ______, skeletal muscles, and joints to the CNS
