"pyramid" like projection on the temporal bone directly posterior to the external auditory meatus.

Named after the greek word for "breast", so think of the "saggy breast" looking bone on the side of the temporal brain.

A long, thin projection of the temporal bone on the underside of the cranium.  Because of how thin this bone is, it is constanlty broken or removed in real specimins.

Nasal
Definition
The two small bones that make up the bridge of the nose.  Bordered by the frontal and Maxilla
Term
Vomer
Definition
The nose that  creates the nasal septum in the posterior of the nasal cavity.  To view this bone, you must look at the nasal cavity from the posterior, or look through the nasal cavity
Term

Hyoid

 

Definition

A bone positioned inferior to the lower jaw.  Provides muscle attachment for the starp-like muscles of the front of the neck and also prevents these muscles from crushing the trachea.

 

That separate bone thing.

Term
Maxilla
Definition
The two bones holding the upper teeth.  Forms the medial inferior border and floor of the eye orbit
Term
Sphenoid
Definition

An extensive bone, somewhat butterfly-shaped.  It has visible surfaces in several areas of the skull.


If the interior of the skull is shown, then it's the sphenoid!

"Head Bredth".  The most lateral point on each side of the calvarium.
Term
Lambda
Definition

Term
Opisthocranion
Definition

Term
Bregma
Definition
