functions
Functions
  • Support
  • Protect
  • Produce blood cells
  • Store minerals and fat
  • Provide movement
types of bones
Types of Bones
  • Long
  • Short
  • Flat
  • Irregular
long bone
Long bone
  • = longer than they are wide, tubular shape
  • Examples: femur, tibia, fibula, humerus, radius, ulna
  • Compact bone: dense (found at ends)
  • Spongy bone: cancellous (found in shaft)
  • Hematopoiesis = red blood cell formation
    • Occurs in spongy bone
short bone
Short bone
  • = cube shape, lengths and widths equal
  • Example:
    • Metacarpals
    • Metatarsals
    • phalanges
flat bone
Flat bone
  • = plate like, broad surfaces
  • Examples:
    • Cranium
    • Sternum
    • Ribs
    • pelvis
irregular bone
Irregular bone
  • = varied shapes with connections for other bones
  • Examples:
    • Vertebrae
    • Patella
    • Sphenoid
joints
Joints
  • Classified by:
    • Amount of movement they allow
    • According to their structure
  • 3 Types
    • Synarthrosis
    • Amphiarthrosis
    • Diarthrosis
  • Synarthrosis
    • Sometimes fused together
    • Examples:
      • Innominate (ischium, ilium, pubic)
      • Sacrum
      • Cranium (sutures)
joints1
Joints
  • Amphiarthrosis
    • = slightly moveable
  • Examples:
    • Pubic symphysis
    • Manubrium & Sternum
    • Coraco-acromial jt.
joints2
Joints
  • Diarthrosis
    • Aka synovial
    • = freely moveable
    • 6 types
  • 1. saddle
    • Thumb, freely moveable
  • 2. ball and socket
    • Hip, shoulder. Movements in all planes
  • 3. Pivot
    • Prox radius/ulna. Rotation only
  • 4. Hinge
    • Elbow, knee. Flexion and extension
  • 5. Gliding
    • Carpas/tarsals, ribs/vertebrae.
  • 6. Condyloid
    • Scaphoid/radius, occipital/atlas. All movements but rotation
