Anatomy

3. Muscular wall that separates the thorax from the abdominal region and helps control breathing.
5. Also known as occipitofrontalis; the broad muscle that covers the top of the skull and consists of the occipitalis and frontalis.
7. nerve Branch of the seventh cranial nerve that affects the muscles of the mouth.
9. Extensor muscle of the wrist involved in flexing the wrist.
10. Smaller bone in the forearm (lower arm) on the same side as the thumb.
14. Muscles that draw a body part, such as a finger, arm, or toe, away from the midline of the body or of an extremity.
16. glands Also known as ductless glands; glands such as the thyroid and pituitary gland that release hormonal secretions directly into the bloodstream.
18. vessels Tube-like structures that include arteries, arterioles, capillaries, venules, and veins.
19. Fluid part of the blood in which the red and white blood cells and platelets flow.
20. Whitish cords made up of bundles of nerve fibers held together by connective tissue, through which impulses are transmitted.
23. Body organs that control the body’s vision.
24. Body organs that excrete water and waste products.
25. Study of human body structures that can be seen with the naked eye and how the body parts are organized; the science of the structure of organisms or of their parts.

1. Heavy, long bone that forms the leg above the knee.
2. Body organ that removes waste created by digestion.
4. Middle part of the muscle.
6. system Body system that consists of the brain, spinal cord, and nerves; controls and coordinates all other systems of the body and makes them work harmoniously and efficiently.
8. Also known as collarbone; bone that joins the sternum and scapula.
11. Tiny, thin-walled blood vessels that connect the smaller arteries to the venules. Capillaries bring nutrients to the cells and carry away waste materials.
12. Connection between two or more bones of the skeleton.
13. Muscular, cone-shaped organ that keeps the blood moving within the circulatory system.
15. Secretions, such as insulin, adrenaline, and estrogen, that stimulate functional activity or other secretions in the body. Hormones influence the welfare of the entire body.
17. Structures composed of specialized tissues designed to perform specific functions in plants and animals.
21. Muscles that straighten the wrist, hand, and fingers to form a straight line.
22. Spongy tissues composed of microscopic cells in which inhaled air is exchanged for carbon dioxide during one breathing cycle; organs of respiration.
