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
