Why is the fifth cranial nerve important?
It is of particular importance in dentistry since it provides the nerve supply to the jaws and the teeth. The fifth cranial nerve contains both motor and sensory fibers. Thus, it has a motor root supplying motor impulses to the muscles of mastication and a sensory root supplying sensory impulses from the structures of the head and face. ...
What are the twelve pairs of cranial nerves?
Twelve pairs of cranial nerves arise in the brain and give off branches to the structures of the head and face . These nerves leave the cranial cavity through foramina in the base of the cranium. The fifth cranial nerve (the trigeminal nerve) is the largest of the twelve pairs. See figure 2-13. It is of particular importance in dentistry since it provides the nerve supply to the jaws and the teeth. The fifth cranial nerve contains both motor and sensory fibers. Thus, it has a motor root supplying motor impulses to the muscles of mastication and a sensory root supplying sensory impulses from the structures of the head and face. Before leaving the cranial cavity, the sensory root divides into three branches or divisions.
Where does the anterior palatine nerve end?
The anterior palatine nerve emerges upon the hard palate through the greater palatine foramen, and passes forward nearly to the incisor teeth where it ends with fibers of the nasopalatine nerve. It supplies the gingiva (gum tissue), the mucous membrane, and the glands of the hard palate and part of the soft palate.
Which division of the mandibular nerve supplies sensation to the mandible and the teeth?
c. Mandibular Nerve or Third Division. This division supplies sensation to the mandible and the teeth. It contains somatic motor fibers as well as sensory nerve fibers. (The first two divisions are primarily sensory.) This nerve passes downward to enter the mandible through the mandibular foramen.
Which nerve has no somatic motor fibers?
It contains no somatic motor fibers. (1) The maxillary teeth. The maxillary nerve on each side passes forward in the floor of the orbit of the eye. It first gives off the posterior superior alveolar branch to the three maxillary molars.
Which nerve innervates the oral cavity?
Each of the three divisions is divided into many branches. The branches of the maxillary nerve and the mandibular nerve are those that innervate the region of, and around, the oral cavity and will be discussed in the most depth in this section.
What is the most important nerve in the oral cavity?
When discussing the function of the oral cavity, probably the most important nerve is the trigeminal . The trigeminal nerve or fifth CN is the largest of the CNs and is the major sensory nerve of the face and scalp. It originates in the large semilunar or trigeminal ganglion, a group of nerve cell bodies located on the superior surface of the petrous portion of the temporal bone in a small depression (the semilunar fossa) medial to the foramen ovale. The trigeminal nerve divides into three major divisions (or three nerve branches). (Hint: “tri” in trigeminal refers to the nerve’s three divisions.) Division I (the ophthalmic [ahf THAL mik] nerve) and Division II (the maxillary nerve) are only afferent (sensory). Division III (the mandibular nerve) is both afferent (sensory) and efferent (motor). Its efferent fibers supply the muscles of mastication. This is the only CN with sensory (touch and pain) innervation to the skin of the face, and the divisions or branches are distributed to the face as shown in Figure 14-37.
What nerve is felt by the ophthalmic, maxillary, and mandibular branches?
FIGURE 14-37. General distribution to the skin of the three sensory divisions of the trigeminal nerve. Pain in these areas is felt by impulses sent through the ophthalmic ( yellow ), maxillary ( green ), and mandibular branches ( red) or divisions of this nerve. These three branches are distributed to the face as indicated in this drawing. (Reproduced from Clemente CD, ed. Gray’s anatomy of the human body. 30th ed. Philadelphia, PA: Lea & Febiger, 1985:1164, with permission.)
What nerves are responsible for interpreting postural information?
The interpretation of postural information by the brain (sense of position) is called proprioception . Proprioceptive nerve receptors are located in muscles and ligaments, including the periodontal ligaments, and in the lateral aspects of the TMJ. The periodontal ligament around each tooth is well supplied with proprioceptive neurons from the maxillary and mandibular divisions of the trigeminal nerve. These branches send messages to the brain as to the relative position of the mandibular to maxillary teeth. This has a tremendous influence on relative jaw position, movement, and occlusion (the fitting together) of the teeth. Canines are reported to have the richest supply of proprioceptive nerve endings.
Which nerve innervates the soft tissue of the nasal septum and gingiva?
Another long branch of the pterygopalatine nerve, the nasopalatine nerve , runs along the roof of the nasal cavity, then diagonally downward and anteriorly along the nasal septum where it enters the bone of the palate to emerge onto the anterior palate through the incisive foramen. This branch innervates the soft tissue of the nasal septum and gingiva and palatal soft tissue lingual to the anterior teeth (anterior red lines in Fig 14-39 ). The right and left nasopalatine nerves combined with the greater palatine nerves innervate the soft tissue of the entire hard palate (shown as all red lines in Fig. 14-39 ).
Where is the buccinator nerve located?
Another branch is the buccal ( buccinator [BUCK sin a tor] or long buccal) nerve, which comes off just below the foramen ovale and passes through the infratemporal space between the two heads of the lateral pterygoid muscles and then down and forward to the buccinator muscle ( Fig. 14-41) where it innervates the mucosa and skin of the cheek up to the corner of the mouth and the buccal gingiva in the area of the mandibular molars and sometimes the second premolars. The best place to anesthetize the tissue supplied by the buccinator nerve is to inject inside the cheek to deposit the anesthetic into the buccinator muscle near the mandibular molars ( Fig. 14-42 ).
