2. Bodies defense for dirt, bacteria, and germs.  Epidermis- Outer most layer of skin  Dermis- Thicker layer below the epidermis

3.  Functions  1. Protect vital organs  2. Acted on by muscles to produce movement.

4.  Hinge joints- elbow and knee, they move back and forth.  Ball and socket joints- one end of the joint is in the shape of a ball, and the other end of the joint is a cuplike shape.

5.  Function- absorb shock, allow smooth bone movement, and join structures.

6.  Function- contraction of muscles allow for acceleration and deceleration of body.  Help maintain normal posture.

7.  Connect muscle to bone

8.  Connect bone to bone

9.  Small, fluid filled sacs, located in joints.  Provide extra cushion for the structures located in the joint.

10.  Soft-Tissue  Bones

11.  Sprain  Strain  Incision  Abrasion  Contusion  Laceration  Avulsion  Puncture

12.  Injury to a ligament

13.  Injuries to muscles or tendons

14.  1 st degree (mild)- some stretching, little pain, little swelling, no loss of motion.

16.  2 nd degree (moderate)- more stretching, some tearing, pain, swelling, and some loss of motion.

18.  3 rd degree (severe)- complete tear, severe pain, good deal of swelling, loss of motion.

20.  An open wound made by a cutting object.

21.  A cut caused by a non-cutting object.

27.  Results from scrapping off a layer of skin.

31.  Commonly called a bruise.  Cause: direct blow. Signs/Symptoms: swelling and discoloration.

35.  The partial tearing away of a body part.

38. Occurs when a pointed object enters a body part.

43.  Stage I-Acute Inflammatory

45.  Stage II-Repair

47.  Stage III-Remodeling

49.  Dislocations  Subluxations  Fractures

50.  When a force displaces the bones that make up a joint, so they no longer are aligned.

55.  A partial dislocation, or one that does not remain unaligned.

56.  Avulsion  Stress  Spiral  Longitudinal  Compression  Oblique  Comminuted  Greenstick  Transverse  Depressed  Blowout  Pathological  Epiphyseal

57.  When a ligament or tendon pulls so hard that the attachment point pulls part of the bone away.

61.  Occurs when there is repetitive pounding / motion.

64.  When a torque like force is applied to a bone, and the fracture starts at one end and works its way around the length of the bone.

66.  A fracture that runs the length of a bone.

67.  Occurs when opposite forces are applied to a bone at the same time.

69.  When a bone fractures into pieces.

72.  Occurs to bones that are not fully developed, and they only break part way through.

75.  When a fracture occurs straight across a bone.

76.  Usually occurs from a direct blow to the skull.

79.  When the eye is pushed so hard into the back of the eye socket.

83.  When a fracture occurs in the epiphysis (growth plate) of the bone.

86.  Any fracture where the bone protrudes through the skin.

89.  Pain  Deformity  Decrease or loss of motion  Swelling  Crepitis

90.  Stage I-Acute  Stage II-Repair  Stage III-Remodeling
