Study Notes
Cranial Nerves and Oral Cavity Function
- Glossopharyngeal Nerve (IX) is responsible for motor innervation to the stylopharyngeus muscle, which elevates and widens the pharynx during swallowing.
- Glossopharyngeal Nerve (IX) provides general sensation to the posterior one-third of the tongue.
- Facial Nerve (VII) innervates the submandibular and sublingual salivary glands.
- Trigeminal Nerve (V) provides motor innervation to the muscles of mastication, including the masseter, temporalis, and medial and lateral pterygoids.
- Glossopharyngeal Nerve (IX) provides general sensation to the pharynx.
- Hypoglossal Nerve (XII) primarily controls the movement of the tongue.
- Parotid gland receives parasympathetic innervation from the glossopharyngeal nerve (IX), which stimulates salivary secretion.
- Facial Nerve (VII) provides taste sensation to the anterior two-thirds of the tongue.
Oral Anatomy and Physiology
- Incisive foramen is the passageway for the nasopalatine nerve, which provides sensation to the anterior palate.
- Trigeminal Nerve (V), specifically the mandibular branch, provides motor innervation to the tensor veli palatini muscle, which tenses the soft palate during swallowing.
- Molars are primarily used for grinding and chewing food.
- Individuals without wisdom teeth typically have 28 teeth.
- Greater palatine artery provides additional blood supply to the hard palate.
- Facial Nerve (VII) is responsible for taste sensation in the anterior two-thirds of the tongue.
- Greater palatine foramen does NOT function as a pathway for nerve fibers, but rather as a passageway for the greater palatine artery and nerve.
- Glossopharyngeal Nerve (IX) innervates the stylopharyngeus muscle.
- Virginia opossums have a total of 5 tooth types on each side of their mouth: incisors, canines, premolars, and molars.
- Lemur's first premolar is unique because it is larger than other premolars and has one cusp and two roots.
- Saliva plays several important roles in the oral cavity, including lubricating food, dissolving food particles, and initiating digestion through salivary enzymes.
- Distal in dental terminology refers to the surface farthest from the midline of the dental arch.
- Malocclusions can lead to uneven wear of teeth, difficulty chewing, and increased risk of periodontal disease.
- The tongue is primarily structured as a muscular organ covered in mucous membrane.
- The sulcus terminalis, a V-shaped groove, divides the body and root of the tongue.
- Facial Nerve (VII) innervates the submandibular and sublingual salivary glands.
- Circumvallate papillae have the highest concentration of taste buds.
- Genioglossus muscle, the largest tongue muscle, protrudes the tongue out of the mouth.
- The facial nerve (VII) is responsible for conveying taste sensation from the anterior two-thirds of the tongue.
Muscles of the Oral Cavity
-
Tensor veli palatini muscle tenses the soft palate.
-
Styloglossus muscle retracts and elevates the tongue.
-
Hyoglossus muscle depresses and retracts the tongue.
-
Genioglossus muscle protrudes the tongue.
-
Trigeminal Nerve (V) innervates the tensor veli palatini muscle.
-
Filiform papillae do not contain taste buds; they are primarily involved in texture sensation.
-
Circumvallate papillae are large, dome-shaped structures located at the back of the tongue. They contain taste buds and are innervated by the glossopharyngeal nerve (IX) for taste sensation.
