  17. foramen
    an often rounded hole which pierces a bone
  18. parietal
    forms the roof of the skull and encases the top and lateral sides of the brain
  19. temporal
    forms the sides and base of the skull at the temples. it also forms the posterior portion of the cheekbone and articulates with the lower jaw. the auditory meatus(ear whole) pases through this bone
  20. frontal
    forms the forehead, including the brow ridge and upper surface of teh eye sockets
  21. ethmoid
    forms the roof of the nasal cavity and a portion of the base of the skull. (interior roof of the nose)
  22. sphenoid
    forms a portion of the base of the skull and is visible on the side of the cranium between the frontal and temporal bones, it is the location of the pituitary gland. (outside bone of the eye)
  23. occipital
    (back of skull)forms the base of the skull, and surrounds the foramen magnum( big whole in skull) whick is the opening for the spinal cord. it articulates with the atlas by tow occipital condyles
  24. maxila
    joins ot form the upper jaw, the anterior hard palate, and provieedes sockets for the upper teeth
  25. zygomatic
    forms the cheekbones and connects the maxillary bones to the frontal and temporal bones

    joins to form the base of the nose
  28. inferior nasal concha

  30. mandible
    forms the lower jaw and contains scokest for the lower teeth

  33. transverse foramina
    provide a passage for the verebral arteries, and are found only on cervical vertebrae
  34. atlas
    is modified to articulat with the occipital condyle, which enalbes vertical up and down movement of the skull.
  35. axis
    is also highly modified. it has a large medial process called the dens. articulates with the axis providing a pont of rotation which enables the horizontal turning of the skull
  36. thoracic vertebrae
    these are the verebrae of the chest to which ribs attach, and have long spinous processes which increase in height, inferiroly
  37. lumbar
    these vertebrae form the lower back. the bodies are large and thick with long transvers processes, and shor, wide spinous processes
  38. sacrum
    this is the result of the fusion of the five sacral vertebrae, and articulates with the coccyx and the pelvic gridle
  39. coccyx
    this bone is the result of the fusion of between tree to five caudal , or tail, verebrae. is often called tail bone
  40. sternum
    this is commonly known as the breastbone. it is a falt narrow bone in te center of the upper chest, it articulates with the clavicles (collarbones) and the ribs
  41. true ribs
    the costal cartilage attaches these ribs directly to the sternum. true ribs increase in length, inferiorly
  42. false ribs
    the firs three pairs of false ribs are indirectly connected to the sternum by carilage attached to the costal cartliage of teh last true rib
  43. floating ribs
    are the last two pairs of false ribs. they donot connect to teh sternum. the false rivs become shorter, inveriorly
