  6. 6. Marie Jaja Tan Roa Santa The Skeletal System Your body is built around a living framework called Skeletal System. Your skeletal system is primarily composed of bones.
  7. 7. Marie Jaja Tan Roa Santa At birth, you have 350 bones. As you grow older, some bones fuse together to form larger bones and you are left with 206 bones as an adult.
  8. 8. Marie Jaja Tan Roa Santa Two main groups of bones
  9. 9. Marie Jaja Tan Roa Santa The Axial Skeleton Made up of the skull, ribs and vertebrae. 80 bones 40% of the bones in the human.
  10. 10. Marie Jaja Tan Roa Santa The skull is a bony structure that forms the head of the skeleton in most vertebrates. It is a framework of a bone enclosing the brain. The Axial Skeleton:The Skull
  11. 11. Marie Jaja Tan Roa Santa The skull helps protect the brain.
  12. 12. Marie Jaja Tan Roa Santa
  13. 13. Marie Jaja Tan Roa Santa The vertebral column (spinal column and backbone) is made up of of a series of irregularly shaped bones. It runs from the base of the skull to the pelvis. The Axial Skeleton:Vertebral Column
  14. 14. Marie Jaja Tan Roa Santa Functions of theVertebral Column Forms a tube which houses and protects the spinal cord. Provides protective channels for the lower spinal nerves. Supports the weight of the body and head.
  15. 15. Marie Jaja Tan Roa Santa The Axial Skeleton:The Ribcage The thoracic cage or rib cage is composed of 12 pairs of ribs plus the sternum for a total of 25 separate bones.
  16. 16. Marie Jaja Tan Roa Santa ribs The rib cage form a protective cage around the heart and lungs and some vital organs. ribcage Function of the Ribcage

  19. 19. Marie Jaja Tan Roa Santa The Appendicular Skeleton enable us to stand up tall, walk up stairs, and climb.
  20. 20. Marie Jaja Tan Roa Santa The shoulder girdle consists of the clavicle or collar bone and the scapula or shoulder blade. The arm bone or humerus, forms a joint with the scapula above and with two forearm bones at the elbow. The Appendicular Skeleton:The Shoulder Girdle
  21. 21. Marie Jaja Tan Roa Santa Pelvic bones The pelvic bones provide support for the spine and some body organs, and is very stable part of the body It is the largest bone in our body The Appendicular Skeleton:The Pelvic Bones (Hips)
  22. 22. Marie Jaja Tan Roa Santa The bones in our body are also connected with each other. The point where two bones meet and connect is called joint.
  23. 23. Marie Jaja Tan Roa Santa Joints are classified into (1) movable joint and (2) fixed joint or immovable joint. The movements of our body originate in our joints.
  24. 24. Marie Jaja Tan Roa Santa Movable Joints
  25. 25. Marie Jaja Tan Roa Santa 1. Ball-and-socket Joint  Your arms and shoulder, upper leg and hip is connected in a ball-and-socket joint. Shoulder joint Hip joint
  26. 26. Marie Jaja Tan Roa Santa Functions of Ball-and-socket Joint  The ball-and-socket joint allow various movements, such as twisting, rotation, and up-and-down movement.
  27. 27. Marie Jaja Tan Roa Santa 2. Hinge Joint  Hinge joints are formed between two or more bones where the bones can only move along one axis to flex or extend
  28. 28. Marie Jaja Tan Roa Santa Hinge Joint Movement  Your elbows and knees are hinge joints.
  29. 29. Marie Jaja Tan Roa Santa 3. Pivot Joint  A pivot joint is located between the bones in your neck below your skull and lets you turn your head from left to right.
  30. 30. Marie Jaja Tan Roa Santa Movable Joint: Pivot Joint  Pivot joint is a joint in which a bone rotates around another.
  31. 31. Marie Jaja Tan Roa Santa Pivot Joint Movement
  32. 32. Marie Jaja Tan Roa Santa Fixed Joint or Immovable Joints Fixed joint  In an immovable joint, the bones are tightly held together such that they cannot move.
  33. 33. Marie Jaja Tan Roa Santa  Fixed joints are seams between bones that lie directly against each other, or are separated only by a thin layer of connective tissue.
  34. 34. Marie Jaja Tan Roa Santa  Ligament are white , cordlike bands that hold the bones at the joints.  They help the bones move up and down around easily. Ligament
  35. 35. Marie Jaja Tan Roa Santa  The ends of the bones in the joints are protected by smooth, slippery cartilage.  The cartilage serves as a cushion that has natural oil for the smooth movement of the bones. cartilage
  36. 36. Marie Jaja Tan Roa Santa  Another type of connective tissue is the tendon.  Tendon is a white, tough tissue at the end of each muscles to the bones.
  37. 37. Marie Jaja Tan Roa Santa Functions of the Skeletal System 1.The skeletal system forms a strong framework for the body support. It also gives shape to the body. Without this support, we cannot stand, walk, or sit.
  38. 38. Marie Jaja Tan Roa Santa Functions of the Skeletal System 2.The skeletal system protects vital organ of the body.  The vertebrae protects the spinal cord  The skull protects the brain  The rib cage protects the heart and lungs  The pelvic bones protect the kidneys and other part of the abdomen
  39. 39. Marie Jaja Tan Roa Santa Functions of the Skeletal System 3.The bones of the skeletal system, along with the muscles, allow the body to move.
  40. 40. Marie Jaja Tan Roa Santa AMAZING FACTS:  The smallest bone in the human body is the stirrup, which is located in the ear.  The largest bone is the pelvic and the longest bone is the femur  Although the outer part of a bone is hard, it is generally light and soft inside.  Your funny bone isn’t a bone at all. It’s a mass of nerves that runs along the long bone in your arm called humerus.

  56. 56. Marie Jaja Tan Roa Santa How do muscles move??! HOW MUSCLES MOVE
  57. 57. Marie Jaja Tan Roa Santa  The main function of the muscular system is contraction.  Muscles are most often found in pairs. Each muscle has two ends, one of which is called origin, attached to a fixed attachment. The other end is the insertion. The insertion is the movable attachment of the muscles.
  58. 58. Marie Jaja Tan Roa Santa Muscles can only move in one direction, they only contract (pull).When a muscle isn’t contracting, its relaxing. Muscles have different strengths and lengths and provide different amounts of pull.
