which nerves do not deal with the pulp
nasopalatine nerve, and palatine nerves
what is the exception for the posterior superior alveolar nerve
mesialbuccal root of the maxillary 1st molar
masseteric nerve, posterior and anterior temporal nerve, medial pterygoid nerve, lateral pterygoid nerve are what type of nerves
efferent (motor) of the mandibular nerve
motor- to muscles of mastication, tensor tympani, tensor beli palatine (soft palate muscle), mylohyoid, and anterior belly of digastric. Is the description for what cranial nerve
sensory- opthalmic branch cornea, ciliary body, iris, lacrimal gland, conjunctiva, nasal mucosa, eyelid, eyebrow, forehead, and nose. One of the sensory functions for which cranial nerve?
the maxillary branch of the Trigeminal cranial nerve (v) is a sensory for what
skin of cheek, lower lid, side of nose, upper jaw, teeth, mucosa, and maxillary sinus.
The mandibular branch of the trigeminal nerve (v) is a sensory nerve for what
lower jaw, teeth, and mucosa
to facial muscles, muscles of scalp and ear, stapedius, and stylohyoid and posterior belly of digastric muscles. also contains parasympathetic fibers to submandibular and sublingual salivary glands and lacrimal, nasal, and palatine glands. what nerve is in charge of these motor functions
facial nerve (vii)
sensory function for the facial nerve (VII)
(N. intermedius)- from taste buds in anterior two thirds of tongue
- general sensation from lateral of soft palate and adjacent pharynx and external auditory meatus
sensory function for the glossopharyngeal nerve (IX)
from taste buds in posterior third of tongue.
- sensation from fauces, tonsils, pharynx, and soft palate.
motor function for the glossopharyngeal nerve (IX)
to pharyngeal muscle (stylopharyngeal) and parasympathetic innervation to parotid gland (secretions)
hypoglossal (XII) motor function
muscles of the tongue
origin of the trigeminal nerve (v)
nerve ganglion, where trigeminal nerve branches into V1, V2,V3
this branch of the trigeminal nerve exits skull through the superior orbital fissure. It's all sensory
ophthalmic nerve (division 1 (V1) of the trigeminal nerve
this trigeminal branch exits the skull through the foramen rotundum and lies in the pterygopalatine fossa, supplies the upper teeth and oral cavity, the nasal cavity, and the skin of the cheek, the midface, and the temporal region. It's all sensory
maxillary nerve division II V2 of the trigeminal nerve (V)
in the petrygopalatine fossa, the maxillary division divides into what branches?
nasopalatine nerve, palatine nerve (which divides into greater and lesser palatine nerves), posterior superior alveolar nerve, infraorbital nerve, and zygomatic nerve.
this nerve passes through the incisive canal and supplies the 1. palatal mucosa in the anterior region of the palate 2. the palatal gingiva of the max central and lateral incisors and canines 3. palatal portion of the alveolar process of the max central and lateral incisors and canines.
branches of the descending palatine nerve
anterior palatine nerve. after entering the oral cavity through the great palatine foramen this nerve goes to 1. palatal gingiva of premolar and molar teeth 2. mucosa of the hard palate 3. the periodontal ligament and palatal portion of the alveolar process of the premolar and molar teeth
greater palatine nerve
middle and posterior palatine nerves. after entering the oral cavity through the lesser palatine foramen, these nerves go to tonsils and mucosa of the soft palate
lesser palatine nerve
this nerve arises from the max nerve in 1 or 2 branches just before the max nerve enters the infraorbital canal (where it is referred to as the infraorbital nerve)
posterior superior alveolar nerve
branches of this nerve are 1. pulp of the max molar teeth through the apical foramina, with the expection of the mesiobuccal root of the mx 1st molar 2. buccal gingiva in the max molar and premolar regions 3. PDL and the buccal portion of the alveolar process of the max molar teeth 4. the mucosa of the max sinus and the cheek
posterior superior alveolar nerve
branches of the infraorbital nerve
anterior superior alveolar n, middle superior alveolar n, and lateral nasal n
this is a direct branch of the maxillary nerve
posterior superior alveolar n
what nerve innervates the mand teeth?
inferior alveolar n
