The paranasal sinuses are a series of cavities arranged one after another. All species have '''frontal''' and '''maxillary''' systems.

*All species have ''Frontal'' and ''Maxillary'' systems

 

**''Frontal'': consists of space(s) within the bones between the cranial cavity and the [[Nasal Cavity - Anatomy & Physiology|nasal cavity]].

'''Frontal''': Consists of space(s) within the bones between the cranial cavity and the [[Nasal Cavity - Anatomy & Physiology|nasal cavity]].

**''Maxillary'': this is the largest sinus, and consists of the space within the caudolateral part of the upper jaw, above the caudal cheek [[:Category:Teeth - Anatomy & Physiology|teeth]]. This increases with age due to wearing and ventral relocation of the [[:Category:Teeth - Anatomy & Physiology|teeth]].
