ThE BrAiN
Across
- 1. one of the four main subdivisions of each cerebral hemisphere. It occupies the upper central area of each hemisphere.
- 4. a large tract of nerve fibers running across the longitudinal fissure of the brain and connecting the cerebral hemispheres
- 5. a neuron whose axon carries impulses away from the CNS toward an effector.
- 7. the most posterior (rearward) subdivision of each cerebral hemisphere, roughly shaped like a pyramid
- 9. the system controlling rest, repair, enjoyment, eating, sleeping, sexual activity, and social dominance, among other function
- 11. neural signals are transmitted from one neuron to another
- 14. any of a large number of chemicals released by neurons to mediate transmission of nerve signals across the junctions (synapses) between neurons.
- 15. the posterior of three bulges that appear in the embryonic brain as it develops from the neural tube.
- 16. the layer of gray matter that covers the outside of the cerebral hemispheres in the brain
- 17. flexibility and adaptability
- 18. its ability to act as an integrated whole in affecting a large number of smooth muscle systems simultaneously,
- 19. the portion of the nervous system that lies outside the brain and spinal cord.
- 20. one of the four main subdivisions of each cerebral hemisphere in the brain, lying immediately below the lateral sulcus on the outer surface of each hemisphere.
Down
- 2. the portion of the nervous system innervates smooth muscle and glands, including the circulatory, digestive, respiratory, and reproductive organs.
- 3. one of the four main lobes of each cerebral hemisphere of the brain, lying in front of the central sulcus.
- 6. the part of the nervous system comprising the sensory and motor neurons that innervate the sense organs and the skeletal muscles,
- 8. the entire complex of neurons, axons, and supporting tissue that constitute the brain and spinal cord.
- 10. neuron that conducts impulses from a sense organ to the brain or spinal cord.
- 12. basic cellular unit of nervous system.
- 13. the part of the brain that develops from the anterior section of the neural tube in the embryo, containing the cerebrum and the diencephalon.
