Axial Skeleton
What are the bones that make up the orbit of the skull?
• Frontal bone• Zygomatic bone • Maxillary bone • Sphenoid bone • Ethmoid bone • Lacrimal bone • Palatine bone
Hyoid
The hyoid is a U shaped bone that helps support the tongue.
Skull
The skull is a framework that closes the brain, it has many different bones that are put together to make the skull.
Mastoid Process
A protrusion on the temporal bone behind the ear, neck muscles are attached It contains small air filled cavities which are called mastoid cells that communicate with the middle ear.
External Occipital Protuberance
The External Occipital Protuberance is near the middle of the occipital squama and is also knows as the “inion”
External Auditory Meatus
Is the ear canal, a curved tube extending from the auricle into the temporal bone, ending at the tympanic membrane.
Zygomatic Process
Zygomatic process is a protrusion of the skull, most of it belongs to the Zygomatic bone. However, there are other bones contributing to it too, known as the frontal bone, maxilla and temporal bone.

Sternum & ribs:
True ribs (7)
False ribs (5)
Manubrium
Body
Xiphoid process
There are a total of 12 ribs in your body, 7 of those are called true ribs, 5 are called false ribs and out of the 5 false ribs there are two that are floating ribs. True Ribs are called true ribs because they are the only ribs that fully connect to your sternum. False ribs don’t each connect to the sternum so that is why they are called false ribs and the floating ribs don’t connect to anything, that’s why they are called floating ribs.

Carpals, metacarpals, & Phalanges:
There are three types of bones in the hand which are carpals, metacarpals, and phalanges. You start with the thumb and count to five. Eight small bones in the bottom of the hand are Pisiform, triquetrum, lunate, scaphoid, hamate, capitate, trapezoid, trapezium. All of these bones are important for movement and structure.
Lower Extremity:
Femur & patella
Tibia & fibula
Tarsals, metatarsals, & phalanges
