Across
- 4. rapid automatic response circuit
- 6. system responsible for producing movement
- 8. lobe containing the primary motor cortex
- 10. automatic action without conscious awareness
- 11. reflex that pulls the body away from danger
- 15. detects the initial stimulus in a reflex
- 17. reason the left hemisphere controls the right side
- 20. response triggered when ACh binds receptors
- 21. motor neurons carrying signals from CNS to effectors
- 23. brain region that initiates voluntary movement
- 24. carries reflex output to the effector
- 27. reflex reflex that relaxes overworked muscles
- 28. structure coordinating timing precision and balance
Down
- 1. neurotransmitter released at the neuromuscular junction
- 2. primary purpose of reflexes in preventing injury
- 3. electrical signal that triggers ACh release
- 5. reflexes involving skeletal muscles
- 7. connection between motor neuron and muscle fibre
- 9. rapid involuntary responses to stimuli
- 12. reduced due to reflexes bypassing conscious processing
- 13. intentional action under conscious control
- 14. site where most motor fibres cross over
- 16. subcortical structures regulating movement patterns
- 18. muscles or glands activated by motor output
- 19. spinal neuron processing reflex signals
- 22. pathway through which motor commands travel
- 25. muscle or gland producing the reflex response
- 26. reflex that keeps muscles ready
