What is the incisive fossa?

What is the incisive fossa?

incisive fossa a slight depression on the anterior surface of the maxilla above the incisor teeth. infraclavicular fossa the triangular region of the chest just below the clavicle, between the deltoid and pectoralis major muscles. infratemporal fossa an irregularly shaped cavity medial or deep to the zygomatic arch.

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.

Between which bones is Canalis Incisivus formed?

the hard palate is formed anteriorly by the inferior face of the palatine process and posteriorly by the horizontal laminae of the palatine bones, all sutured together at the cruciform suture [1].

How many Foramens are incisive?

Nasal Cavity 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 function of the incisive fossa?

Function. The incisive foramen allows for blood vessels and nerves to pass. These include: the pterygoopalatine nerves to the hard palate.

Is foramen same as Canal?

As nouns the difference between foramen and canal is that foramen is (anatomy) an opening, an orifice; a short passage while canal is an artificial waterway, often connecting one body of water with another.

Where do the Palatine nerves come from?

Anatomical terms of neuroanatomy The palatine nerves (descending branches) are distributed to the roof of the mouth, soft palate, tonsil, and lining membrane of the nasal cavity. Most of their fibers are derived from the sphenopalatine branches of the maxillary nerve.

Which foramen is the largest?

The foramen magnum is the largest foramen of the skull.

Which artery passes through incisive foramen?

greater palatine artery
It can be single or multiple. It transmits the greater palatine artery and vein from the oral to the nasal cavity and the nasopalatine nerve in the opposite direction.

What is a maxilla?

The maxilla is the bone that forms your upper jaw. The right and left halves of the maxilla are irregularly shaped bones that fuse together in the middle of the skull, below the nose, in an area known as the intermaxillary suture. The maxilla is a major bone of the face.

What passes through the Vidian canal?

It transmits the nerve of pterygoid canal, (Vidian nerve), the artery of the pterygoid canal (Vidian artery), and the vein of the pterygoid canal (Vidian vein).

What do Palatine nerves do?

Palatine nerves (greater and lesser palatine nerves, as well as the nasopalatine nerve)—to supply the gingiva, mucous membranes of the roof of the mouth (via the greater palatine nerve), soft palate (including uvula), and tonsils (via the lesser palatine nerve) and the palatal structures around the superior anterior …

Where is the foramen of the incisive fossa?

It is located in the maxilla in the incisive fossa, midline in the palate posterior to the central incisors, at the junction of the medial palatine and incisive sutures. It can be single or multiple. It transmits the greater palatine artery and vein from the oral to the nasal cavity and the nasopalatine nerve in the opposite direction.

Where is the fossa located in the human body?

The fossa is located behind the zygomatic process of the frontal bone in the anterior and lateral part of the orbital roof. The fossa is bounded by the anterior and posterior lacrimal crests coming from the maxilla (frontal process) and lacrimal bone respectively, with no definite boundary above.

Where is the fossa of the maxilla located?

The fossa is located behind the zygomatic process of the frontal bone in the anterior and lateral part of the orbital roof. fossa for the lacrimal sac A vertical groove, some 5 mm deep and about 14 mm high, formed by the frontal process of the maxilla and lacrimal bones and which contains the lacrimal sac.

Where are the incisive canals located in the human body?

in·ci·sive fos·sa. the depression in the midline of the bony palate behind the central incisors into which the incisive canals open. incisive fossa. The vertical furrow along the surface of the maxilla beginning between the lateral upper incisor and the canine tooth and extending up toward the anterior nasal aperture.
