Across
- 4. Soma; nucleus-containing part of a neuron that assists the neuron with functions
- 5. The basic cell of the nervous system; sends, processes, and receives neural impulses
- 6. Part of the nervous system in which the brain and spinal cord are associated
- 7. Gap of space between the receiving end of a neuron and the sending end of another neuron
- 8. Fatty insulation wrapped around the axon of a nerve cell that helps neural impulses to move faster as they cross the axon
- 11. Portion of the ANS that takes action during stressful times by mobilizing energy
- 14. a chemical compound that follows pain, pleasure, and memory
- 16. A long, tube-like structure that carries nerve impulses from one neuron to another
- 17. The part of the neuron made of branch-like fibers that receive impulses and then send them to the soma
- 18. A portion of the PNS connecting the CNS to receptors that control skeletal muscles
- 20. Glands throughout the body that secrete hormones through the bloodstream
Down
- 1. An automatic, biologically related response to a stimulus
- 2. The creation of new neurons
- 3. Gray, fatty cells that provide support, deliver impulses, produce myelin, and clean up waste products
- 9. Chemical compound that carries neural impulses from one neuron to another across synapses
- 10. Areas in the cerebral cortex that process information from other parts of the brain for acting, interpreting, and integrating.
- 12. Two lobes of the brain above the ear on either side of the head which are involved in hearing, comprehension, memory, and emotions
- 13. Structures in the forebrain connected to emotions, memory, and physiological functions
- 15. Branch of peripheral nervous system controlling involuntary motor response through connections between sensory receptors and the CNS, smooth and cardiac muscle, and glands.
- 19. Part of the nervous system in which nerves and neurons connect the entire body to the CNS
