|
|
Appendicular Skeleton |
Makes up the bones of the limbs and the pelvic and shoulder area 126 bones |
|
|
Cranium |
Consist of 8 cranial boned Parietal bones Occipital bone Frontal bone Ethmoid bone Sphenoid bone Temporal Bone |
|
|
Adult bone count |
Most have 206 but it may vary |
|
|
Parietal Bone |
2 bones together at the top of the head Forms the top and sides of the cranial Cavity |
|
|
Occipital bone |
Forms the rear of the skull |
|
|
Temporal bones |
Sides of the cranium and part of the cranial floor, the structures of the inner and middle ear |
|
|
Sphenoid bone |
Forms a key part of the cranial floor as well as the floor and side walls of the orbits |
|
|
Ethmoid bone |
Contributes to the walls of the orbits, roof and walls of the nasal cavity and the nasal septum |
|
|
Sella Turcica |
On top of the Sphenoid bone indented area houses the pituitary gland |
|
|
Sutures |
Bones of the skull that join together at immovable joints |
|
|
Mandible |
Only facial bone that can move |
|
|
Hyoid Bone |
U shaped that sits between the chin and larynx. The only bone that doesn't articulate with other bone Attachment point for muscles that control the tongue, mandible, and larynx |
|
|
Paranasal Sinuses |
4 pairs of Sinuses which are named for the bones in which they reside Open into the internal nose Filled with air, they lighten the skull and act as resonators for sound production |
|
|
4 paranasal Sinuses |
Sphenoid sinus Frontal sinus Ethmoid sinus Maxillary sinus |
|
|
Posterior (occipital) fontanel |
The smaller fontanel |
|
|
Hydrocephalus |
Suture lines in a newborn that are abnormally wide. Excessive amounts of cerebrospinal fluid accumulate in the brain, causing the to expand |
|
|
Increased intracranial pressure |
A bulging anterior fontanel signals this Such as may occur following a head injury or infection |
|
|
Dehydration |
Sunken fontanel suggest this |
|
|
Atlas |
C1 role is to support the skull Has no body, delicate ring and a large vertebral foramen Depressions on each side of the vertebrae articulate with bony protections from the occipital bone of the skull When the head moves back and forth (nodding ur head yes) |
|
|
Axis |
C2 has a projection called the dens, or odontoid process. The dens projects into the Atlas and allows the head to swivel from side to side (saying no) |
|
|
True Ribs |
Ribs 1 to 7 Attach to the sternum by a strip of hyaline cartilage (costal cartilage) |
|
|
Anterior fontanel |
Largest fontanel |
|
|
C1 and C2 Vertebrae |
The most unique of all the vertebrae |
|
|
Ribs |
Twelve pairs of ribs attach to the vertebral column |
|
|
False Ribs |
Ribs 8, 9, and 10 attach to the cartilage of rib 7; as well as ribs 11 and 12 |
|
|
Floating Ribs |
Ribs 11 and 12 Do not attach to any part of the anterior thoracic cage |
