What passes through the incisive foramen?
It transmits the greater palatine artery and vein from the oral to the nasal cavity and the nasopalatine nerve in the opposite direction.
Where would you find the incisive foramen?
The incisive foramen (shown as two foramina by Hebel and Stromberg (1976) lies in the midline of the hard palate, between the left and right premaxillae and just behind the upper incisor teeth. The foramen leads to a short canal that connects the nasal and oral cavities.
What is the name of the nerve and exits through the incisive foramen?
nasopalatine nerve
The incisive foramen is the exit site of the nasopalatine canal where the terminal branch of the descending palatine artery and nasopalatine nerve pass into the oral cavity.
What nerve passes through incisive fossa?
The incisive canal, also known as the nasopalatine canal, is an interosseous conduit through the anterior maxilla connecting the oral and nasal cavities. Within this canal lies the nasopalatine nerve and the vascular anastomosis between the greater palatine and sphenopalatine arteries.
What is incisive nerve?
The incisive nerve innervates the pulps of the teeth anterior to the mental foramen, usually the premolars through the centrals on one side. The mental nerve innervates the skin of the chin, lower lip, and facial soft tissues anterior to the mental foramen on one side.
Is foramen and fossa the same?
Foramen – A hole through which nerves and blood vessels pass. Examples include supraorbital foramen, infraorbital foramen, and mental foramen on the cranium. Fossa – A shallow depression in the bone surface. It is the main articulating surface with the adjacent bone, forming a “ball-and-socket” joint.
What does the incisive nerve innervate?
Incisive nerve: Innervates the canines and incisors in the lower jaw. Mental nerve: Plays a sensory role in the lower, forward part of the face.
How do I make an incisive nerve block?
An anesthetic is injected through the skin of the chin into the area around the mental foramen using a small needle. The doctor firmly massages the area for 10-15 seconds. After a few minutes, the area of the mental nerve becomes numb and the procedure can be performed.
What does lingual nerve supply?
The lingual nerve is a sensory branch of the posterior division of the mandibular division of the trigeminal nerve supplying sensation (both gustatory (taste) and non-gustatory) to the anterior two-thirds of the tongue.

What are the different types of incisive foramens?
There are two major groups of cleft lip and palate, anterior and posterior deformities, with the incisive foramen as the dividing landmark. The anterior deformities include cleft lip, with or without cleft upper jaw, and cleft between the primary and secondary palates (Fig. 11.10A, B).
Where are the ethmoidal foramina in a dog?
You will find two ethmoidal foramina in the frontal bone of the dog. This bone articulates with the nasal bone and maxilla rostrally. Again, this bone also articulates with other bones like parietal, sphenoid, lacrimal, palatine, and ethmoid bones. From this frontal bone area, you might identify the following structures –
Where is the incisive foramen on a rat?
Robert Lewis Maynard, Noel Downes, in Anatomy and Histology of the Laboratory Rat in Toxicology and Biomedical Research, 2019 The incisive foramen (shown as two foramina by Hebel and Stromberg (1976) lies in the midline of the hard palate, between the left and right premaxillae and just behind the upper incisor teeth.
Where is the jugular foramen located in a dog’s skull?
The jugular foramen is located between the petrosal part of the temporal bone and the occipital bone of the dog. There is a distinct mastoid process at the petrosal part of the temporal bone. The tympanic part of the temporal bone is the ventral portion and easily identified by its more significant component (bulla tympanic).
