104114 bone-notes

  1. 1. Bone Notes 1. Must know Right vs. Left 2. Spelling is very important for example the coracoid process is on the scapula but the coronoid process is on the mandible and ulna. 3. If there is more than one of a bone marking you must indicate the bone in the name of the marking. *From example above there are 2 coronoid processes one on the mandible and one on the ulna. Therefore coronoid process of the mandible is a complete answer. This is common with the markings head, condyle, epicondyle, styloid process, coronoid process, neck, shaft, tubercle 4. Vertebral anatomy ALL VERTEBRAE HAVE EACH OF THE FOLLOWING 7 BONE MARKINGS Body (except atlas) Vertebral arch Lamina Pedicle Spinous process Transverse process Vertebral foramen (SPINAL CORD PASSES THROUGH THIS) Facets Intervertebral discs Differences are in the table below. Vertebra Number Body Size Spinous Process Other Atlas C1 1 Absent Tiny – only a tubercle No body / transverse foramen Axis C2 1 Double (Dens) Bifid / Straight Double body / transverse foramen Cervical 7 Small Bifid (1-5) / Straight Transverse foramen Thoracic 12 T1 – small T12 – large Pointy / inferior Extra facets for ribs Lumbar 5 Huge Fin-like / straight Transverse processes point lateral 5. Radius is lateral bone of antebrachium (forearm). Fibula is the lateral bone in the crurum (leg). There is NO SUCH THING AS A FIBIA. Remember that in the leg the small bone is fibulateral. This gives spelling and location. 6. There is NO middle phalanx on the 1st digit in the hand or foot.
