1. Cells in your body have specific functions (jobs).
Fat Cell
White Blood Cell
Red Blood Cell
Platelet
Nerve Cell
Bone Cell
Muscle Cell

2. Cells with similar functions working together form a TISSUE.
Muscle Tissue
Nerve Tissue
Adipose Tissue
(fat tissue)
Blood
Bone Tissue

4. EPITHELIAL TISSUE (3 types) Cuboidal cells Squamous cells
Lining of glands, kidneys tubules, ducts of glands
Columnar cells
Squamous cells
Lining of lungs, heart, mouth, blood vessels, and skin.
Lining of stomach, intestines, nose, ears, and tongue

5. CONNECTIVE TISSUE adipose tissue (fat cells)
cartilage (chondroblast cells)
blood (platelets, red and white blood cells)
bone (osteoblast cells)
adipose
cartilage
blood
bone

6. NERVOUS TISSUE
Brain
Spinal Cord
Nerves

7. Skeletal Muscle Tissue
Smooth Muscle Tissue
Skeletal Muscle Tissue
Cardiac Muscle Tissue

8. SMOOTH MUSCLE Not striated Involuntary Not branched Slow to tire
Found in blood vessels, stomach, intestine, esophagus,
Not striated
Involuntary
Not branched
Slow to tire

9. Tires when working hard
SKELETAL MUSCLE
attaches to and moves bones.
Striated
Voluntary
Not branched
Tires when working hard

10. CARDIAC MUSCLE Found only in the heart. Striated Involuntary Branched
Never tires

11. Two or more tissues working together make up an ORGAN.

13. Organs working together make up an ORGAN SYSTEM.

15. is the state of having a stable internal environment.
Homeostasis
is the state of having a stable internal environment.

16. OBJECTIVES Discuss the functions of the skeletal system.
Describe the structure of a bone.

17. FUNCTIONS OF THE SKELETAL SYSTEM
Provides shape and support
Allows movement
Protects vital organs and tissues
Stores certain materials
Produces blood cells

18. The Skeletal System is the body’s living framework.
206 bones make up the skeleton.
The Skeletal System is the body’s living framework.

19. Most of the skeletal system is made up of bones, ligaments, tendons, and cartilage (connective tissues).

20. The skeleton is divided into two parts.
Axial skeleton
Appendicular skeleton

21. Appendicular Skeleton
Axial Skeleton
Appendicular Skeleton
skull
shoulders
ribs
breastbone
arms and hands
vertebral column
pelvis/hips
legs and feet

22. Axial Skeleton
Protects the Organs.

23. Appendicular Skeleton
Provides Movement

24. Development of Bone

32. Ball and Socket A ball and socket joint allows for radial movement in almost any direction. They are found in the hips and shoulders.

33. Hinge A hinge joint allows extension and retraction of an appendage.

36. Injuries to the skeletal and muscular systems.
Sprain – ligaments and tendons are torn or pulled beyond their stretching range.
Fracture – a break in the bone.
Dislocation – when a bone is forced out of its joint.

37. The End!
