C3.1 Integration of Body Systems

3. Physiological processes and behaviors that follow an approximately 24-hour cycle.
5. Brain structure primarily responsible for muscle control balance and movement coordination.
9. The process of component parts of a system working together for a function.
10. Hormone produced by the pineal gland that regulates the sleep schedule.
12. The master gland that controls other endocrine glands and body functions.
14. Part of the brain that connects the cerebrum and spinal cord.
18. Receptors that monitor blood pressure by detecting stretch in the arteries.
19. Chemical released at a synapse to stimulate another neuron or muscle fiber.
20. A muscle or gland that carries out a response to a stimulus.
21. Chemical messengers that carry instructions from one set of cells to another.
25. Part of the brainstem that regulates stroke volume and heart rate.
26. System of glands that release hormones to direct body processes.
28. PROPERTIES New properties that result from interacting components but are not in individual parts.
29. Neurons that connect sensory and motor neurons and form complex circuits.

1. Main control center that detects blood changes and stimulates the pituitary gland.
2. Receptors that detect oxygen carbon dioxide and pH levels in the blood.
4. The regulation and maintenance of a stable internal environment in the body.
6. Neurons that convey messages from receptor cells to the central nervous system.
7. The junction between two nerve cells where signals are transmitted.
8. Organs of the endocrine system that manufacture and release hormones.
11. Cells signaling to themselves to regulate their own activity.
13. Endocrine gland near the brain center that produces melatonin.
15. Coordination of different body systems to perform overall functions and sustain life.
16. Neurons that send commands from the brain to muscles or glands.
17. Hormone secreted by adrenal glands during stress to prepare for vigorous activity.
19. An individual cell of the nervous system.
22. ARC A simple fast neural pathway that processes involuntary responses.
23. Branch-like parts of a neuron that receive signals from other neurons.
24. Involuntary waves of muscle contraction that move food through the digestive system.
27. Protective fatty coating that insulates electrical signals in nerve fibers.
