Presentation on theme: "Skeleton."— Presentation transcript:

1 skeleton

2 support

3 the hard structure (bones and cartilages) that provides a frame for the body of an animal

4 structure that holds up or provides a foundation

5 protect

6 muscles

7 shield from danger, injury, destruction, or damage

8 animal tissue consisting predominantly of contractile cells

9 bones

10 cartilage

11 function to move, support, and protect the various organs of the body, produce red and white blood cells and store minerals

12 a stiff yet flexible connective tissue found in many areas in the bodies of humans and other animals. It is not as hard and rigid as bone but is stiffer and less flexible than muscle.

13 cells

14 tissue

15 the basic unit of all living organisms

16 a group of biological cells that perform a similar function

17 marrow

18 calcium

19 the interior of long bones

20 major material used in mineralization of bones and shells

21 pellet

22 movable joints

23 a round ball of undigested matter that some bird species regurgitate

24 A joint in which the opposing bony surfaces are covered with a layer of cartilage and in which some degree of free movement is possible

25 immovable joints

26 gliding joints

27 joint in which the ends of the bones forming the joint are dovetailed together and connected by tough fibrous tissue.

28 joint in which the joint surfaces are flat and allow only a gliding motion

29 ball and socket joints

30 hinge joints

31 the ball-shaped surface of one rounded bone fits into the cup-like depression of a muscle. It enables the bone to move in a 360° angle.

32 A joint, such as the elbow, in which a convex part of one bone fits into a concave part of another, allowing motion in only one plane.

33 flexibility

34 backbone

35 the ability to bend easily or be easily changed

36 the vertebrate spine or spinal column

37 vertebrae

38 spinal column

39 The individual bones of the spinal column which are stacked on top of each other

40 The series of articulated vertebrae, separated by disks and held together by muscles and tendons, encasing the spinal cord and forming the supporting axis of the body

41 opposable

42 strength

43 can be placed opposite something else (ex. the thumb)

44 The power to resist strain or stress

45 articulated

46 tendon

47 United by, or provided with, articulations; jointed (ex. skeleton)

48 A band of tough, inelastic fibrous tissue that connects a muscle with its bony attachment

49 cardiac muscles

50 skeletal muscles

51 The specialized striated muscle tissue of the heart; the myocardium

52 moves the skeleton and is responsible for all our voluntary movements

53 smooth muscles

54 heart

55 Muscle tissue that contracts without conscious control, such as the stomach, intestine, bladder, and blood vessels, excluding the heart.

56 The chambered muscular organ in vertebrates that pumps blood received from the veins into the arteries

57 contract

58 relax

59 To reduce in size by drawing together; shrink

60 To become less restrained or tense

61 vein

62 artery

63 Any of the membranous tubes that form a branching system and carry blood to the heart.

64 Any of the muscular elastic tubes that form a branching system and that carry blood away from the heart to the cells, tissues, and organs of the body

65 involuntary muscle

66 voluntary muscle

67 Muscle not under the control of the will; usually consists of smooth muscle tissue is usually associated with skin.

68 Muscle under conscious control

69 stimulus

70 response

71 An agent, action, or condition that elicits or accelerates a physiological or psychological activity or response.

72 A reaction, as that of an organism or a mechanism, to a specific stimulus.
