On the model below, identify sutures and bones they connect.


On the model below, examine the parts of ethmoid bone and its location in the relation to other bones in the skull.


On the model below, examine the structure of the maxilla and palatine bones.


On the model below, examine the parts of ethmoid and sphenoid bones and their location in the relation to each other and other bones of the skull.


On the model below, look for the frontal, sphenoid and maxillary sinuses. Also, identify vomer.


The next two models show the neonatal skulls. Can you remember the major differences between the adult and neonatal skulls?
