Description: Practice 50 exam-oriented MCQs from Class 12 Biology Chapter 18 – Coordination and Control, covering nervous coordination, neurons, reflexes, brain and spinal cord, endocrine glands, hormones, and homeostasis.
1. Coordination allows different parts of an organism to
2. The nervous system coordinates body activities mainly through
3. The basic structural and functional unit of the nervous system is the
4. The part of a neuron that usually receives signals is the
5. The part of a neuron that carries impulses away from the cell body is the
6. The cell body of a neuron contains the
7. A sensory neuron carries impulses from a receptor toward the
8. A motor neuron carries impulses from the central nervous system to an
9. An interneuron is mainly found within the
10. The central nervous system consists of the brain and
11. The peripheral nervous system consists mainly of
12. The protective membranes surrounding the brain and spinal cord are called
13. The fluid surrounding the brain and spinal cord is
14. The largest part of the human brain is the
15. The cerebrum is mainly involved in

17. The medulla oblongata controls many
18. The hypothalamus plays an important role in
19. The spinal cord is protected by the
20. A reflex action is generally
21. The pathway followed by a nerve impulse during a reflex is the
22. The receptor in a reflex arc detects the
23. The effector in a reflex action is commonly a
24. The gap between two neurons at a synapse is called the
25. Chemical messengers released by neurons at synapses are called
26. Acetylcholine is an example of a

28. In the peripheral nervous system, myelin is produced by
29. The autonomic nervous system mainly controls
30. The sympathetic division generally prepares the body for
31. The parasympathetic division generally promotes
32. The endocrine system coordinates body functions through
33. A hormone is a chemical messenger released by
34. Endocrine glands release hormones directly into the
