Biology Lesson 7.2

  1. 1. Lesson 7.2 Appendicular skeletonConsist of the bones of the upperand lower limbs and their girdlesGirdles – bones where the limbsattach to the bodyThere are two girdles: Pectoral Pelvic
  2. 2. BONES OF THE Upper LIMBS AND Pect0ral GIRDLEPectoral girdle – where the upper limbs attachIncludes the:1) Clavicle (collar bone)Which attaches to the top of the sternum.
  3. 3. Clavicle
  4. 4. BONES OF THE Upper LIMB AND Pect0ral GIRDLEPectoral girdle – where the upper limbs attachIncludes the:1) AND Clavicle (collar bone)2) Scapula (shoulder blade)attaches to axis by ligamentsand muscles which allows theshoulder joint to have thelargest range of motion.braced by the clavicle
  5. 5. Scapula
  6. 6. Bones of upper Appendage1. Humerus - largest bone of armand attaches to the scapula at theshoulder joint Humerus
  7. 7. Bones of upper Appendage1. Humerus2. Ulna  one of two bones of the forearm  bone on the side that has the pinkie (little finger) (UP)  attached to humerus by a hinge joint
  8. 8. Ulna
  9. 9. Bones of upper Appendage1. Humerus2. Ulna3. Radius Second bone of the forearm On the same side as the thumb Rotates around the ulna to twist the forearm
  10. 10. Radius
  11. 11. Bones of the Hand
  12. 12. Wrist1) Carpals – 8 bones that make up the wrist• The articulations of the carpal bones allow the wrist to bend and twist. Pretty good range of motion.
  13. 13. CarpelsBones of the Hand
  14. 14. Wrist(1)Carpals(2) Metacarpals - branchout from the carpalscomposing the main partof the hand.
  15. 15. Metacarpels CarpelsBones of the Hand
  16. 16. Wrist(1) Carpals(2) Metacarpals(3) Phalanges 14 of these form the fingers and thumbs Fingers have three phalanges Thumb has only two phalanges
  17. 17. Phalanges Metacarpels CarpelsBones of the Hand
  18. 18. BONES OF THE LOWER LIMB AND PELVIC GIRDLE
  19. 19. BONES OF THE LOWER LIMB AND PELVIC GIRDLEPelvic Girdle – where the lowerlimbs attach to the axial skeleton.The 2 large pelvic bones thatattach to the sacrum (vertebralcolumn) make up the pelvic girdle.
  20. 20. Pelvicbone
  21. 21. Bones of the lower limb (appendage): Femur  attaches to the pelvic girdle at the hip largest and strongest bone of the body the upper leg
  22. 22. Femur
  23. 23. Bones of the lower limb (appendage): Femur Bones of the lower leg:Two bones make up the lower leg:1) Tibia olarger of two oextends from knee joint to the ankle joint
  24. 24. Tibia
  25. 25. Bones of the lower limb (appendage): FemurBones of the lower leg:Two bones make up the lower leg:1) Tibia2)Fibula Thinner than tibia Tell a little fib Attaches to the tibia Does not rotate like the radius of arm
  26. 26. Fibula
  27. 27. Bones of the lower limb (appendage): FemurBones of the lower leg:Two bones make up the lower leg:1) Tibia2) FibulaPatella – knee cap •found in front of the knee •brace for tendons that straighten leg •shields the knee joint from injury
  28. 28. Bones of the Foot
  29. 29. Bones of the foot:1) Tarsals 7 tarsal bones make up the ankle Allows foot to rotate Talus is largest of tarsal bones – attaches directly to tibia and fibula
  30. 30. TarsalsBones of the Foot
  31. 31. Bones of the foot:1) Tarsals2) Calcaneus – heel bone calcaneus
  32. 32. Bones of the foot:1) Tarsals2) Calcaneus3) Metatarsals •in front of tarsals •five of them •make framework of instep and ball of foot •arranged in curved arches
  33. 33. Metatarsals TarsalsBones of the Foot
  34. 34. Bones of the foot:1) Tarsals2) Clcaneus3) Metatarsals 4) Phalanges attach to metatarsals five of them Made of three bones each except for big toe is only 2 like in hands
  35. 35. Phalanges Metatarsals TarsalsBones of the Foot
  36. 36. THE FOOT IS A MIRACULOUS DESIGN: supports the body on asmall arches allowing it to move and be balanced!!!!!
