Anatomy Lab #2: Axial Skeleton Flashcards
Name the bones of the cranium?
Frontal, Parietal (2), Temporal (2), Occipital, Sphenoid, and Ethmoid
Name the bones of the face?
Nasal (2), Maxillas (2), Zygomatic (2), Mandible, Lacrimal (2), Palatine
(2), Inferior nasal conchae (2), Vomer
What is the significance of the zygomatic processes of the temporal bones?
Possesses mandibular fossa
& articular tubercle which articulates with the condylar process of the mandible to form the
temporomandibular joint
What is the significance of the mastoid processes of the temporal bones?
Attachment point for neck
muscles
What is the significance of the foramen magnum of the occipital bone?
Allows the spinal cord & blood
vessels to pass into & out of the brain
What is the significance of the occipital condyles of the occipital bone?
What is the significance of the occipital condyles of the occipital bone?
What is the significance of the sella turcica of the sphenoid bone?
Cradles the pituitary gland
What is the significance of the cribriform plate of the ethmoid bone?
Contains olfactory foramina which
allow the olfactory nerves to enter the brain from the nasal cavity
What is the significance of the crista galli of the ethmoid bone?
Attachment points for the brain
membranes (meninges)
What are alveolar processes? Where do you find them?
Sockets for teeth; Maxillae & mandible
Where would you find the mental foramen?
Mandible
Does the hyoid articulate with other bones?
NO
What are the divisions of the vertebral column?
Cervical, Thoracic, Lumbar, Sacrum, Coccyx
What is the vertebral foramen?
Space formed by pedicles, lamina, & body of the vertebrae; contains
the spinal cord
What is the intervertebral foramen?
Formed by the superior & inferior vertebral notches of each
pedicles; permits the passage of the spinal nerves into & out of the vertebral column
