Study Notes
-
The mouth consists of two parts: the vestibule and the mouth proper.
-
Vestibule: a slit-like space between the gums, teeth, lips, and cheeks. Communicates with the exterior through the oral fissure.
-
Cheek forms the lateral wall of the vestibule and is made up of the buccinator muscle.
-
Mouth proper: has a roof formed by the hard and soft palate, and a floor formed by the anterior two-thirds of the tongue.
-
Hard palate: bony part formed by the maxilla and palatine bones, separated by crucicular suture.
-
Soft palate: a mobile fold of mucous membrane attached to the posterior border of the hard palate.
-
Contains the uvula, a conical projection in its free posterior border.
-
Muscles, nerves, and vessels cover its upper and lower surfaces.
-
Tensor veli palatini and levator veli palatini are two muscles that help tighten the soft palate.
-
Greater and lesser palatine nerves, nasopalatine nerve, and glossopharyngeal nerve supply nerves and sensory innervation to the soft palate.
-
Tongue: a mass of striated muscle covered with mucous membrane. Divided into anterior and posterior thirds, and right and left halves by a median fibrous septum.
-
Muscles attach the tongue to the styloid process, soft palate, mandible, and hyoid bone.
-
Tongue lies partly in the mouth and partly in the pharynx.
-
Pharyngeal plexus of nerves supplies motor innervation to all muscles of the palate except tensor veli palatini.
-
Maxillary nerve provides sensory innervation to the palate through greater, lesser palatine, and nasopalatine nerves.
-
Blood supply to the palate comes from the greater and lesser branches of the maxillary artery, ascending palatine branches of the facial artery, and the ascending pharyngeal branch of the external carotid artery.
-
The tongue's movements can be tested by saying "Ah" and observing the soft palate's upward movement and uvula's backward motion.
