A muscular organ in the oral cavity that enables taste sensation, chewing, swallowing and speaking. Motor: All muscles are innervated by hypoglossal nerve (CN XII), except for palatoglossus which is supplied by vagus nerve (CN X). Structures of the oral cavity.

Which nerve is the primary source of innervation for the oral cavity?

The innervation of the oral cavity is distinct and comes primarily from the maxillary and mandibular divisions of the trigeminal nerve. The oral mucosa, teeth, and supporting structures receive their innervation from the maxillary and mandibular divisions of the trigeminal nerve.

What are the two regions of the oral cavity?

The oral cavity is surrounded by the lips and is composed of two separate regions, the vestibule, the area between the cheeks, teeth, and lips, and the oral cavity proper.

Where do blood vessels and nerves pass through?

Running down the center of each osteon is the central canal, or Haversian canal, which contains blood vessels, nerves, and lymphatic vessels. These vessels and nerves branch off at right angles through a perforating canal, also known as Volkmann’s canals, to extend to the periosteum and endosteum.

The blood vessels of your oral cavity Veins of the oral cavity generally follow the arteries and have the same names. The veins of the palate drain into the pterygoid venous plexus. The lingual veins of the tongue drain into the internal jugular vein.

What is the difference between the vestibule and the oral cavity?

It is the space between the lips/cheeks, and the gums/teeth. The vestibule communicates with the mouth proper via the space behind the third molar tooth, and with the exterior through the oral fissure. Fig 1 – The two divisions of the oral cavity are the vestibule and oral cavity proper.
