3. 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
5. Skull
The skull is a framework that closes the brain, it has many
different bones that are put together to make the skull.
6. 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.
7. External Occipital Protuberance
The External Occipital Protuberance is near the
middle of the occipital squama and is also knows as
the “inion”
8. External Auditory Meatus
Is the ear canal, a curved tube extending from the auricle
into the temporal bone, ending at the tympanic
membrane.
9. 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.
10. Bones in skull:
Parietal Bone
Frontal Bone
Sphenoid bone
Temporal bone
Occipital bone
11. Bones in skull cont.:
Nasal bone
Ethmoid bone
Vomer bone
Maxillary bone
Lacrimal bone
Inferior nasal concha
Mandible bone
15. Sternum & ribs:
Manubrium
True ribs
(7)
Body
Xiphoid
False
process
ribs (5)
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.
21. 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, sca
phoid, hamate, capitate, trapezoi
d, trapezium. All of these bones
are important for movement and
structure.
