Bones of the (blank) are divided into those of the braincase and those of the face |
Skull |
|
(Neurocranium), which encloses the cranial cavity, consists of 8 bones that immediately surround and protect the brain |
Braincase |
|
Form the structure of the face |
Facial bones |
|
How many facial bones are solidly connected to form the bulk of the face |
13 |
|
Forms a freely movable joint with the rest of the skull |
Mandible |
|
Form a large portion of the side of the head |
Parietal bones and temporal bones |
|
Temporal refers to? |
Time |
|
Is so named because the hairs of the tenples turn white , indicating the passage of time |
Temporal bone |
|
Two bones join each other on the side of the head at the |
Squamous suture |
|
Is a joint uniting bones of the skull |
Suture |
|
Anteriorly, the parietal bone is joined to the |
FRONTAL BONE by the CORONAL SUTURE, Posteriorly it is joined to the OCCIPITAL back of the bone by the LAMBDOID SUTURE |
|
A canal that enables sound waves to reach the eardrum |
External auditory canal |
|
The temporal bone can be seen and felt as a prominent projection just posterior to the ear |
Mastoid process |
|
Important neck muscles involved in rotation of the head attach to the |
Mastoid process |
|
Part of the (blank) can be seen immediately anterior to the temporal bone |
Sphenoid bone |
|
Actually a single bone that extends completely across the skull. |
Sphenoid bone |
|
Anterior to the sphenoid bone is the |
Zygomatic bone |
|
Consist of joined process of the temporal and zygomatic bones, forms a bridge across the side of the face and provides a major attachment site for a muscle moving the mandible |
Zygomatic arch |
|
Forms the upper jaw |
Maxilla |
|
Forms the lower jaw |
Mandible |
|
Articulates by suture to the temporal bone |
Maxilla |
|
Contains the superior set of teeth, and the mandible contains the inferior set of teeth |
Maxilla |
|
The major structures seen from the frontal view are the |
Frontal bone, zygomatic bones, maxillae and the mandible |
|
Frontal view, the most prominent openings into the skull are the |
Orbits and the nasal cavity |
|
Cone- shaped fossae, so named because the eyes rotate within them |
Orbits |
|
Each orbit has several openings through which structures communicate with other cavities. The largest of these are the |
Superior and inferior orbital fissures |
|
Divides the nasal cavity into right and left halves |
Nasal septum |
|
The bridge of the nose is formed by the |
Nasal bones |
|
Is a separate bone, and the middle and superior conchae are projections from the ethmoid bone |
Nasal conchae |
|
Each if the lateral walls of the nasal cavity has three bony shelves, called the |
Nasal conchae |
|
Several of the bones associated with the nasal cavity have large cavities within them, called the |
Paranasal sinuses |
|
The skull has additional sinuses, called the (blank) located inside the mastoid process of the temporal bone |
mastoid air cells |
|
Through which the spinal cord joins the brain, is located in the posterior fossa |
Foramen magnum |
