may be to help direct airflow to the olfactory region in the posterior part of the nasal cavity (Van Valkenburgh et al.2014b). In this olfactory region, blind recesses are formed between complex turbinates covered in olfactory epithelium. These turbinates may be attached to ethmoid, frontal ...
Peripheral branches of the ganglia run through foramina in the ethmoid bone into the region of the nasal sacs and blowhole. Round to oval ganglion cells are scattered along the nerve and thousands of similar cells are found in the dural ganglia where they are encapsulated by satellite cells. A...
The upper jaw has a double ethmoid and a palatobasal connection, but no otic connection; the dermal bone attachment for the quadrate is different to other placoderms. A separately ossified cartilage behind the mandibular joint is comparable to the interhyal of osteichthyans. Two articular ...
