1. Functions of the Skeletal System
    • Support. Bone is hard and rigid; cartilage is flexible yet strong.  Cartilage in nose, external ear, thoracic cage and trachea.
    • Connect body parts. Ligaments - bone to bone. 
    • Protection. Skull around brain; ribs, sternum, vertebrae protect organs of thoracic cavity. 
    • Movement. Produced by muscles on bones, via tendons. Ligaments allow some movement between bones but prevent
    • excessive movement. 
    • Storage. Ca2+ and Phosphorus. Stored then released as needed. Adipose tissue stored in marrow cavities.
    • Blood cell production. Hemopoietic tissues formation of blood cells. Bone marrow (produces all three) that gives rise to blood cells (red = erythrocytes, white = leukocytes, and platelets = thrombocytes).
  2. Components of the Skeletal System
    • Bones:
    • compact bone
    • spongy (trabecular or cancellous) bone 
    • Cartilages:
    • Hyaline cartilage
    • Fibrocartilage
    • Elastic cartilage
    • Tendons:
    • attachment of muscle to bone 
    • Ligaments:
    • attachment of bone to bone
  3. Osteoblasts
    Immature bone cell. Formation of bone through ossification or osteogenesis.
  4. Ossification
    In which bones are formed. Formation of bone by osteoblasts.
  5. Osteocyte
    Maintain the bone matrix. Mature bone cells.
  6. Osteoclasts
    • Destructive bone cell.
    • Resorption of bone.
  7. Which two (2) cells are involved in bone remodeling?

  8. Irregular Bones

  9. Flat Bones
    Ribs, sternum, skull, and scapulae.
  10. Short Bones

  12. Structural Classification of Bone
    • Long: Ex. Upper and lower limbs. 
    • Short: Ex. Carpals and tarsals. 
    • Flat: Ex. Ribs, sternum, skull, scapulae. 
    • Irregular: Ex. Vertebrae, facial.
  13. Structure of Long Bone
    • Dyaphysis: Shaft 
    • Epiphysis: End (tips) of the bone 
    • Epiphyseal plate: Growth plate. Present until growth stops. 
    • Epiphyseal line: Bone stops growing in length (former growth Epiphyseal plates become lines). 
    • Periosteum: Outer covering (membrane) of long bone. 
    • Medullary cavity: Center of dyaphysis is hallow cavity.  It is lined with spongy bone known as Edosteum. 
    • Edosteum: Inner lining of the hallow (Medullary) cavity. 
    • Sharpey's Fibers: act as glue to attach the periosteum to the dyaphysis (bone).
