Across
  1. 2. maintains the health of the neuron
  2. 4. potential neuron polarized; is recharged waiting for heat, change, light
  3. 6. role: inhibition of brain activity; disorders: seizures, tremors, insomnia, anxiety disorders (low)
  4. 7. sheath that covers the axon of some neurons to help speed neural impulses
  5. 10. nervous system that controls the body's skeletal muscles, controls all VOLUNTARY movement
  6. 11. roles: movement, thought processes, pleasure and rewarding sensations; disorders: Parkinson's (low levels), Schizophrenia (excessive levels), drug addiction
  7. 13. drug molecules that are similar enough to the neurotransmitter to mimic its effects ex: opiate drugs bc enough like endorphins
  8. 14. carries info away from cell body to muscles, glands, cells
  9. 15. electrical messages that can cross synapse
  10. 17. the synaptic gap/cleft; the junction between the axon tip of a sending neuron and the dendrite or the cell body of the receiving body
  11. 18. a nerve cell, basic building block of the nervous system, basic unit of communication
  12. 19. roles: phys. arousal, learning, memory; disorder: depression (low levels)
  13. 20. roles: learning, memory, muscle coordination; disorder: Alzheimer's
Down
  1. 1. nervous system that arouses the body, mobilizing its energy in stressful situations
  2. 2. roles: emotional states or moods, sleep, hunger, arousal; disorder: depression
  3. 3. nervous system that calms the body, conserving energy
  4. 5. type of CNS neurons that internally communicate and intervene between the sensory inputs and motor outputs
  5. 8. role: memory; disorders: migraine, seizures (both excess levels)
  6. 9. when a receiving neuron does not accept a neurotransmitter, the sending neuron absorbs it
  7. 10. the minimum level of stimulation needed to activate the next neuron
  8. 12. nervous system that controls the glands and muscles; INVOLUNTARY
  9. 16. type of neurons that carry incoming information from the sense receptors to the CNS
