Lateral view :-Various skull bones seen in lateral view consists of premaxilla, nasal process of premaxilla, nasal, prefrontal, interorbital septum, frontal, supraorbital, parietal, postorbital, supratemporal fossa, supratemporal arch, squamosal,’ supratemporal, prootic, epipterygoid, quadrate, occipital condyle, exoccipital, basisphenoid, pterygoid, orbitosphenoid, parasphenoid, transverse, palatine, jugal, lacrymal, maxilla, septomaxillary, dorsal premaxillary foramen, premaxilla.Ventral view :- Various skull bones in ventral view consists of premaxilla, maxilla, vomer, ventral borer of inter orbital septum, palatine, transverse, jugal, sub-orbital fossa, pterygoid, postorbital, quadrate, squamosal, columella, basioccipital, paraoccipital process of exoccipital, occipital condyle, exoccipital, basisphenoid, parasphenoid, orbitosphenoid, ventrolateral process of frontal, position of posterior nare, vomer, vomerine aperture, apparatus for Jacobson’s organ and vomeromaxillary process of premaxilla. ![]() Dorsal view :- Various skull bones seen are as follows- Dorsal premaxillary foramen, septomaxillary nasal, prefrontal, lacrymal, supraorbital fossa, frontal parietal foramen, parietal, epipterygoid, prootic, supratemporal arch, supratemporal, prootic, supraoccipital, foramen magnum, columella, squamosal, quadrate, supratemporal fossa, postorbital, pterygoid jugal, transverse, palatine, ventral bogeler of inter orbital septum, vomer, maxilla, nasal process of premaxilla, premaxilla and paraoccipital process of exoccipital. ![]() Structures seen in ventral view are rostrum, anterior opening of orbitonasal canal ethmopalative ridge, accessory cartilage of infra-orbital ridge, floor of cranium, foramen for internal carotid artery, carotid canal, and exit of IXth nerve.Occipital crest, ridge of semicircular canal and anterior fontenelle. Other structures seen in dorsal view are foramen lodging olfactory lobe, foramen for ophthalmicus profundus nerves, posterior opening of orbitonasal canal, anterior orbital process, parietal fossa, foramen for IXth nerve.Rostrum is made by a ventro-median rostral-cartilage and two dorsolateral rostral cartilages. It includes the anterior part of cranium, two nasal or olfactory capsules and rostrum. Number of foramina or nerves are found within orbit. Each orbital region is made up dorsally by supra-orbital ridge, ventrally by infra-orbital ridge, anteriorly by pre-orbital process and posteriorly by post-orbital process. Orbital region :- Orbital region contains eye during life time.Below postorbital process, articular surface for hymandibula of hyoid arch is seen. This region dorsally contains openings for endolymphatic duct and perilymphatic foramen. Protuberances for semicircular canals can be seen. Auditory region :- Lies in front of occipital, in the form of two auditory capsules one on each side.Lateral sides contain occipital condyles and occipital crest in the middle. ![]()
