| Question | Answer |
| What 5 muscles make up the soft palate? | Tensor veli palatini, levator veli palatini, palatoglossus, palatopharyngeus and musculus uvulae |
| What is the innervation of all the muscles of the soft palate (except for Tensor veli palatini)? | Pharyngeal branch of CN X via the pharyngeal plexus |
| What is the innervation of tensor veli palatini? | Nerve to medial pterygoid- a branch of CNV3 (via otic ganglion) |
| How many permanent/secondary teeth does an adult have? | 32 (16 in each jaw) |
| How many primary/deciduous teeth does a child have? | 20 |
| What nerve supplies innervation to the mandibular teeth? | Inferior alveolar nerve (CNV3) via the inferior dental plexus |
| What nerve supplies the innervation to the maxillary teeth? | Superior alveolar nerve (CNV2) via the superior dental plexus |
| The palatine gingivae of the incisiors is supplied by what nerve? | Nasopalatine nerve (CNV2) |
| What nerve innervates the labial and buccal/ right and left vestibular maxillary gingivae? | Anterior, middle and posterior superior alveolar nerve (CNV2) |
| Which arteries supply the palate? | The main blood supply is from the right and left greater palatine arteries |
| Where do the right and left greater palatine arteries originate from? | The descending palatine artery (from the 3rd part of the maxillary artery) |
| Where does venous blood from the palate drain to? | The pterygoid venous plexus |
| Which nerve supplies innervation to the SOFT palate? | Lesser palatine nerves |
| What nerve(s) supply the hard palate? | Greater palatine nerves supplies most of the hard palate, with contributions from nasopalatine nerve |
| What groove seperates the anterior and posterior parts of the tongue? | The terminal sulcus (a V shaped groove) |
| What are the four types of papillae found on the tongue? | Vallate, foliate, filiform and fungiform |
| Where are the taste buds located? | In the papillae |
| Which papillae lie anterior to the terminal sulcus? | Vallate papillae |
| What are the three main branches of the lingual artery? | Dorsal lingual, deep lingual and sublingual arteries |
| Where does the lingual artery originate from? | External carotid artery |
| Where does lymph from the apex of the tongue and frenulum drain to? | Submental lymph nodes |
| Where does lymph from the posterior third of the tongue drain to? | Superior deep cervical lymph nodes |
| Where does lymph from the medial part of anterior two thirds of the tongue drain to? | Inferior deep cervical lymph nodes |
| Where does lymph from the lateral parts of the anterior two thirds of the tongue drain to? | submandibular lymph nodes |
| The deep lingual veins begin at the apex of tongue and run posteriorly beside lingual frenulum to join which vein? | Sublingual vein |
| Give three functions of saliva. | Keeps the mucous membranes of the mouth moist, lubricates food during mastication and begins digestion of starches |
| What structure passes through the incisive fossa of the hard palate? | The nasopalatine nerve (from CNV2) |
| What structure passes through the greater palatine foramina of the hard palate? | The greater palatine nerve (from CNV2) |
| What nerve passes through the lesser palatine foramina of the hard palate? | The lesser palatine nerve (from CNV2) |
