- 34. Automatic reaction that involves sending an impulse from a sensory receptor along the sensory nerve to the spinal cord
- 35. Thin layer of tissue that surrounds the cell; it protects the interior of the cell from its surroundings and is semipermeable, meaning it allows certain substances to enter the cell
- 38. Group of similar cells that perform a specific function
- 39. Fluid that travels through the circulatory system to supply oxygen and nutrients to cells and tissues and to remove carbon dioxide and waste from them
- 40. System that carries oxygen-rich blood from the heart throughout the body and returns oxygen-poor blood back to the heart; also known as general circulation
- 42. Whitish bundles of nerve fibers that transmit impulses
- 43. Middle part of the muscle

- 48. Glandlike structures that filter bacteria, viruses, and cancer cells and are connected by lymph vessels
- 50. Skeleton of the head; divided into two parts called the cranium and facial skeleton
- 51. (striated) Muscles that we control at will
- 52. Process of breaking complex molecules down into simple molecules; releases energy
- 53. System of nerves connecting the peripheral (outer) parts of the body and motor nerves; carries impulses to and from the CNS
Down
- 1. The study of the functions or activities performed by the body's structures
- 2. Process of cell reproduction that occurs when the cell divides into two identical daughter cells
- 3. Part of the nervous system that controls involuntary muscle action and regulates the action of the smooth muscles, glands, blood vessels, heart and breathing
- 4. Also known as efferent nerves; carry impulses from the brain to the muscles or glands; these transmitted impulses produce movement
- 6. Well organized body system composed of the brain, spinal cord, and nerves; controls and coordinates all other body systems
- 7. Body System that helps defend against infection and includes lymph, lymph nodes, thymus gland, spleen, and lymph vessels
- 9. Controls voluntary muscle actions and consists of the brain, spinal cord, spinal nerves, and cranial nerves; it allows you to taste, smell, see, hear, think, breathe, move, run, sleep, remember, sing, laugh, and write
- 11. Makes up a cell; contains nutrients, mineral salts, and water
- 14. Study of the structure, function, and pathology of the nervous system
- 16. Body system consisting of a group of specialized glands that control the growth, development, reproduction, and health of the entire body
- 19. Also known as the cardiovascular system or vascular system, controls the body's steady circulation through the heart and blood vessels
- 21. Part of the muscle that does not move and is anchored to the bone; attached closest to the skeleton
- 22. Also known as ductless glands; include the pituitary, thyroid, and adrenal glands, as well as other glands that release hormones directly into the bloodstream
- 24. Forms the physical foundation of the body and is composed of 206 bones that vary in size and shape; connected by movable and immovable joints
- 25. Framework of the face; composed of 14 bones

- 29. Medical term for chewing
- 31. Body system consisting of skin and its accessory organs, such as the oil and sweat glands, sensory receptors, hair, and nails, it serves as a protective covering and helps regulate the body's temperature
- 32. Muscular, cone-shaped organ that keeps the blood moving within the circulatory system
- 33. Oval, bony case consisting of eight bones that protect the brain
- 36. The basic units of all living things
- 37. Movable part of the muscle anchored to the bone; attached farthest from the skeleton
- 41. Also known as duct glands; include the sebaceous and sudoriferous glands, as well as others, and produce a substance that travels through small tubelike ducts
- 43. Tubelike structures that circulate blood throughout the body including the arteries, arterioles, capillaries, venules, and veins
- 45. The portion of the central nervous system that originates in the brain and extends down to the bottom of the spine
- 46. Also known as systems; groups of body organs acting together to perform one or more functions
