An Introduction to the Human Body

Across

5. mechanism that intensifies a change in the body’s physiological condition in response to a stimulus
8. describes a position below or lower than another part of the body proper; near or toward the tail; also referred to as caudal
11. two-dimensional, horizontal plane that divides the body or organ into superior and inferior portions
13. steady state of body systems that living organisms maintain
14. describes a position above or higher than another part of the body proper; also referred to as cranial
18. membrane that covers organs and reduces friction; also referred to as serous membrane
19. face down
20. describes a position below or lower than another part of the body proper; near or toward the tail; also referred to as inferior
24. describes the middle or direction toward the middle of the body
25. describes a position nearer to the point of attachment or the trunk of the body
26. two-dimensional, vertical plane that divides the body or organ into right and left sides
27. standard reference position used for describing locations and directions on the human body
31. describes the front or direction toward the front of the body; also referred to as anterior
32. division of the anterior (ventral) cavity that houses the heart, lungs, esophagus, and trachea
33. describes the front or direction toward the front of the body; also referred to as ventral
34. serous membrane that lines the pleural cavity and covers the lungs
35. describes a position farther from the point of attachment or the trunk of the body
36. process by which unspecialized cells become specialized in structure and function
38. two-dimensional, vertical plane that intersects the body at an angle and is not parallel of perpendicular to any of the other three commonly used planes
39. science that studies the form and composition of the body’s structures
40. ideal value for a physiological parameter; the level or small range within which a physiological parameter such as blood pressure is stable and optimally healthful, that is, within its parameters of homeostasis

Down

1. application of ultrasonic waves to visualize subcutaneous body structures such as tendons and organs
2. medical imaging technique in which a device generates a magnetic field to obtain detailed sectional images of the internal structures of the body
3. homeostatic mechanism that tends to stabilize an upset in the body’s physiological condition by preventing an excessive response to a stimulus, typically as the stimulus is removed
4. (also, receptor) reports a monitored physiological value to the control center
6. organ that can cause a change in a value
7. form of high energy electromagnetic radiation with a short wavelength capable of penetrating solids and ionizing gases; used in medicine as a diagnostic aid to visualize body structures such as bones
9. medical imaging technique in which a computer-enhanced cross-sectional X-ray image is obtained
10. describes the back or direction toward the back of the body; also referred to as dorsal
12. medical imaging technique in which radiopharmaceuticals are traced to reveal metabolic and physiological functions in tissues
15. describes a position above or higher than another part of the body proper; also referred to as superior
16. describes a position farther from the surface of the body
17. two-dimensional, vertical plane that divides the body or organ into anterior and posterior portions
21. division of the anterior (ventral) cavity that houses the abdominal and pelvic viscera
22. describes the back or direction toward the back of the body; also referred to as posterior
23. face up
28. sac that encloses the heart
29. describes a position nearer to the surface of the body
30. serous membrane that lines the abdominopelvic cavity and covers the organs found there
34. science that studies the chemistry, biochemistry, and physics of the body’s functions
37. describes the side or direction toward the side of the body
