1. KEY CONCEPT The skeletal system includes bones and tissues that are important for: supporting, protecting, and moving your body.

2. Cranium
Label the skeleton:
Humerus
Mandible
Radius
Ulna
Pelvis
Femur
Patella
Tibia
Fibula

3. Vertebrae:

4. Your skeletal system is made up of the appendicular and axial skeletons.
The skeletal system protects, supports, and moves the body.

5. Appendicular skeleton:
legs, arms, feet, hands, scapula, clavicle, pelvis
allows for movement

6. skull, rib cage, spinal column, sternum
Axial skeleton:
skull, rib cage, spinal column, sternum
skull
rib
sternum
vertebra
supports body and protects tissues
allows for limited movement
Vertebrae: bones that surround spinal cord

7. Cartilage is connective tissue between bones. cushions bones
allows for smooth movement
connect two bones
cartilage

8. How many bones are in the human body? 206
What do bones do?
fibrous joint
-framework for muscles to pull against
-shape and structure to body
-support and protect organs
Joints- places where two bones meet.
3 types of joints.

9. 3 types of Joints
Fibrous or fixed:
do not allow for movement
found in skull

10. -allows partial movement -hold vertebrae in place; rib cage
3 types of joints:
Cartilaginous
-allows partial movement
-hold vertebrae in place; rib cage
cartilage

11. 3 types of joints
Synovial joints
-allows for greater movement
-5 types of synovial joints

12. There are 5 types of synovial joints. gliding pivot ball-and-socket
saddle
hinge
GLIDING JOINT
PIVOT JOINT
BALL-AND-SOCKET JOINT
SADDLE JOINT
HINGE JOINT

13. Synovial Joints Type of Joint Example on Body G. Gliding Joint
Type of Movement
Type of Joint
Example on Body
Allows bones to slide over each other
G. Gliding Joint
Wrist, ankle
Side to side, rotate
Top 2 vertebrae of spine
B. Pivot Joint
F. Ball and Socket Joint
Almost any direction, up, down, forward, backward, circular
Shoulder, hip
Rotation, front to back; left to right
E. Saddle Joint
Thumb
Elbow, knee, fingers, toes
One direction,
forward and backward
D. Hinge Joint

14. Ligaments are long bands of tissue that connect bones across a joint.

15. Bones are living tissue.
Bone is made of compact bone tissue and spongy bone tissue.
Compact bone
Spongy bone

16. Compact bone is hard and dense.
Osteocytes (bone cells) maintain compact bone rings.
Haversian canals allow blood vessels in the bone.
blood vessel
osteocytes
Haversian canals

17. Spongy bone protects red or yellow bone marrow.
Red bone marrow produces blood cells.
Yellow bone marrow is mostly fat.
Periosteum
A layer of connective
tissue that covers bone
Red bone marrow

18. Calcification is the process of building hard bone.
combines collagen and calcium phosphate
transforms cartilage into hard bone during childhood
osteocyte
compact bone
