Posterior fontanel Sphenoid fontanel Mastoid fontanel Fig 8 5a b Know all foramens Table 8 3 which allow passage of certain nerves through bone e g Foramen magnum allows spinal cord to run through CBIO2200 Fig 8 5a b Know all foramens Table 8 3 which allow passage of certain nerves through bone e g Foramen magnum allows spinal cord to run through Fig 8 24 Articulations of Yes No Atlas 1st cervical vertebrae Provides for yes range of movement or motion articulate with the occipital condyles of the skull Atlas is the only vertebrae with no body CBIO2200 Axis 2nd cervical vertebrae unique spinous process called dens or odontoid process allows the atlas to rotate on the axis allows head rotation for no range of motion Processes allow for articulation rotation e g odontoid process spinous process temporal process transverse process Fig 8 18 Vertebral Column Cervical vertebrae 7 Thoracic vertebrae 12 Lumbar 5 Sacrum 1 5 foramen on each side Coccyx 1 made up of 3 fused bones CBIO2200 Vertebral vs Invertebral Foramen Vertebral foramina allow spinal cord to pass through Invertebral foramina allow spinal nerves to pass through foramina between discs vertebrae Transverse foramina ONLY cervical vertebrae same for transverse process location in cervical vertebrae Fig 8 25 Cervical vertebrae Thoracic Vertebrae Lumbar Vertebrae CBIO2200 Fig 8 22 8 23 Invertebral Discs
