Regarding the vertebral arch, what is the significance of the lamina? It forms the "roof" of the vertebral foramen. It is a site of muscle attachment and may also articulate with the ribs. It transfers weight along the axis of the vertebral column. It articulates with the inferior articular processes of a more superior vertebra.

It forms the "roof" of the vertebral foramen.

The crista galli, a structural feature of the ethmoid bone, is described as which of the following? It is a bony ridge that projects superior to the anteromedial floor of the cranium. It forms part of the nasal septum. It is a delicate projection of the lateral masses. It forms the posterior part of the hard palate.

It is a bony ridge that projects superior to the anteromedial floor of the cranium.

Which nasal complex structure is paired with the correct description? -Ethmoidal air cells - A network of cells whose mucous secretions flush the surfaces of the nasolacrimal canal -Maxillary sinuses - Largest of the sinuses, and produce mucus secretions that flush the inferior surfaces of the nasal cavities -Sphenoidal sinuses - Extremely small in size and located on either side of the body of the sphenoid, superior to the sella turcica -Frontal sinuses - Always extremely large in size and variable in time of appearance
