The Study Of Human Movement

Front 1

What is the Purpose of the Skeleton?

Back 1

1. Support internal organs
2. Provide for muscular attachment
3. Provide levers for movement
4. Red blood cell production (femur)
5. Protection/defense
6. Storage of minerals (calcium)(magnesium)

Front 2

How many bones are in the human body?

Back 2

206 bones are in the human body

Front 3

What are bones made with?

Back 3

1. 20-25% H2O (80 when born decreases to 60)
2. 60-70% Calcium phosphate,calcium carbonate, protein mineral matrix, salts(provides density & resists compression)
3. Collagen- strong materal
(Elastic protein that resists forces of tension)
4. Capable of resisting up to 6 times its mass if healthy
(ostioprosis not healthy)

Front 4

What are the two Skeletal Divisions?

Back 4

Axial & Appendicular

Front 5

Axial Skeleton:

Back 5

1. Skull
2. Vertebral column
3. Bony thorax (ribs & sternum)
(supports the head, neck, and torso)
(Protects brain, spinal cord, heart, & lungs)

Front 6

Appendicular Skeleton:

Back 6

Purpose is for mobility.
Upper and lower limbs
(upper includes shoulder girdle)
(Lower includes pelvic girdle. (hips))

Front 7

Which is more important, the axial or appendicular skeleton?

Back 7

Axial is most important because it protects all the main organs.

Front 8

Of the 206, how many can a person voluntarily engage?

Back 8

177.

Front 9

Name the different types of bones.

Back 9

1. Long
2. Short
3. Flat
4. Irregular
5. Sesamoid

Front 10

Can some bones fit into more then one catergory?

Back 10

Yes.
(Example- the small bones in your wrist are both short and irregular.)

Front 11

Long bones

Back 11

1. cylindrical shaft
2. Protruding (knobby) ends
3. Shaft has a medullary canal
4. Provide rigid framework of bodies levers.

Front 12

Name some long bones.

Back 12

Phalanges (fingers), Metatarsals (toes), Metacarpals (hand), Tibia (big leg), fibula (small leg), Femur, radius (arm thumb), ulna, humerus (arm)

Front 13

Short Bones

Back 13

Small, chunky, and solid bones. For example your carpols (hand), and foot.

Front 14

Flat bones

Back 14

curved surface and vary from thick to thin. Example your ribs and your scapula (back of shoulder)

Front 15

Irregualr Bones

Back 15

Irregualr shaped bones. Example your vertebrae and your pelvic girdle.
