Presentation Transcript

  1. Presentation on Axial and Appendicular Skeleton www.AssignmentPoint.com

  2. Skull Vertebral column Thoracic cage Remaining 126 bones of Pectoral girdle Pelvic girdle Attached limbs Axial vs. Appendicular

  3. SKULL • Cranium vs. facial bones • Special case:hyoid bone Sutures: • Lambdoidal • Sagittal • Coronal • Squamosal

  4. Vertebral Column and Spinal Curvatures Abnormal curvatures • Kyphosis • Lordosis • Scoliosis Alternating concave and convex curves

  5. breakfast, lunch & dinner times Typical vertebra has 7 processes (function?) Atlas & Axis (special joint!) Intervertebral discs (anulus fibrosus + nucleus pulposus) Vertebrae

  6. Thoracic Cage • Sternum • 12 pairs of ribs • True vs. false ribs • Vertebrosternal, vertebrochondral, vertebral • Cracked ribs (composition of rib bone? displaced fractures uncommon, why?)

  7. Girdles with their associated extremities Pectoral girdle: clavicle and scapula Upper limb: humerus, ulna, radius, carpal bones, hand Pelvic girdle: Os coxae Lower limb: femur, patella, tibia, fibula, tarsal bones, foot Appendicular Division

  8. Scaphoid (Navicular) Lunate Triquetrum Pisiform Trapezium Trapezoid Capitate Hamate 8 carpal (or wrist) bones: From lateral to medial, first proximal then distal Sally Lowers Tim’s Pants, Then Things Can Happen

  9. The Hand • Metacarpals: bones in palm of hand • Numbered from lateral to medial • 14 Phalanges • Numbering same as with metacarpals, additionally: proximal, middle and distal phalanx • Pollex has only two phalanges

  10. Appendicular Skeleton: Highlights cont. Two os coxae are made up of 3 fused bones each • ileum • ischium • pubis Compare Male and female pelvis Trueand false pelvis

  11. Femur: surgical vs. anatomic neck (also know major bone markings) • Patella: large sesamoid bone (patellar ligament) • Tibia: medial; fibula: lateral, not weight bearing • The real ankle bones are the malleoli

  12. Calcaneus Talus Navicular Cuboid 3 Cuneiforms (lateral, intermediate, medial) 7 tarsal (or “ankle”) bones: Posterior third of foot From lateral to medial, first proximal then distal Cute Tina Never Could Cooperate

  13. Foot • Naming and numbering of metatarsals and phalanges analogous to hand • Hallux has only two phalanges
