What passes through the infraorbital foramen dog?
The foramen’s facial surface is superior to the canine fossa and inferior to the lower margin of the orbit. It transmits the infraorbital nerve (a branch of the maxillary division of the trigeminal nerve (CN Vb) and infraorbital artery and vein.
Where is the infraorbital foramen located?
This foramen is situated 5 mm from the inferior rim of the orbit, on the same vertical line as the supra-orbital foramen. Frequently sensitive, it is located at the medial two-thirds of the inferior border of the orbit, about 3 cm from the median line.
What nerve emerges from infraorbital foramen?
The anterior superior alveolar nerve branches off the infraorbital nerve just before it exits through the infraorbital foramen. It travels in the anterior wall of the maxillary sinus and supplies the mucous membrane. It gives off branches to the superior dental plexus which supplies the upper incisor and canine teeth.
What goes through the infraorbital canal?
The infraorbital canal is a bony canal within the maxillary bone located at the anterior aspect of the orbital floor. It transmits the infraorbital nerve, which is a branch of the maxillary division of the trigeminal nerve (CN Vb), as well as the infraorbital artery and vein.
What is canine fossa?
The canine fossa constitutes the chief part of the anterior, or facial, surface of the maxilla. It extends from the infraorbital margin above to the alveolar process below, and horizontally from the zygomaticomaxillary suture to the anterior nasal aperture.
What passes through the superior orbital fissure?
This fissure, which separates the greater and lesser wings of the sphenoid and lies between the optic foramen and the foramen rotundum, provides passage to the three motor nerves to the extraocular muscles of the orbit: oculomotor nerve (CN III), trochlear nerve (CN IV), and abducens nerve (CN VI).
How do you palpate the infraorbital foramen?
To palpate the infraorbital foramen, have the patient look straight ahead and imagine a line drawn vertically (sagittally) from the pupil down toward the inferior border of the infraorbital ridge. Keep the palpating finger in place over the inferior border on the infraorbital rim for the remaining steps.
Is the infraorbital foramen the same as the infraorbital canal?
Anatomy of the eye and orbit Before it reaches the orbital margin this fissure becomes the infraorbital canal, which opens as the infraorbital foramen 4 mm below the orbital margin on the anterior surface of the maxilla (Figs 1-3C, 1-4 and 1-5A).
How do you palpate infraorbital foramen?
Where is the canine fossa?
maxilla
The canine fossa constitutes the chief part of the anterior, or facial, surface of the maxilla. It extends from the infraorbital margin above to the alveolar process below, and horizontally from the zygomaticomaxillary suture to the anterior nasal aperture.
What is the canine eminence quizlet?
What is a canine eminence? Bony labial ridge on maxillary canine.
