The Axial Skeleton Flashcards
Occipital Condyle
Articulates with C1 (atlas)- “Yes”.
Foramen Magnum
Where medulla oblongata and spinal cord are going to attach
External occipital protuberance
Attachment of ligaments to support head
Sella turcica
Where the pituitary gland is going to sit when it’s attached to your brain
Crista galli
Attachment for meninges
Hyoid
Does not articulate with any other bone, only bone in the body that does not touch another bone, suspended between mandible and larynx, site of attachment for your tongue.
Vertebral Column
Spine is composed of a series of bones called the vertebrae.
Intervertebral foramen
Formed for the exiting spinal nerves between each vertebrae,as the vertebrae stack up it is going to create holes that the nerves are going to be able to come out of.
Vertebral foramen
Where the spinal cord is going to be housed.
Intervertebral disc
Tough fibrocartilage going to help with coushining and making sure things don’t compress, absorbing shock.
Cervical vertebrae (C1-C7 neck region)
Atlas- C1 going to support your head will help you say yes
Axis- C2 you can move your head back and forth and so you can say no
Thoracic Vertebrae (T1-T12)
Articulate with ribs to form thoracic rib cage.
Lumbar Vertebrae (L1-L5)
Are going to bear the greatest loads so they have to be larger than the cervical and thoracic vertebrae. No transverse foramen.
Sacrum
Fusion of 5 separate vertebrae
Coccyx
“Tail bone”, fusion of 3-5 separate vertebrae.
