Is inferior alveolar nerve sensory or motor?

Which muscle is affected during inferior alveolar nerve block?

The muscle affected during an inferior alveolar nerve block is the temporalis muscle.

Nerve that helps feel a toothache?

On the top (maxilla) it is the superior alveolar nerve. On the bottom (mandible) it is the inferior alveolar nerve.

What are the three branches of the mandibular nerve?

The mandibular nerve, which is the third division of the trigeminal nerve (cranial nerve V), has three main branches: the anterior trunk, the posterior trunk, and the auriculotemporal nerve. The anterior trunk primarily supplies motor innervation to the muscles of mastication and sensory innervation to the buccal region. The posterior trunk provides sensory innervation to the lower jaw, teeth, and tongue through branches such as the inferior alveolar nerve and the lingual nerve. These branches play vital roles in both sensory and motor functions in the lower face and jaw.

Where the inferior alveolar nerve travels?

The inferior alveolar nerve travels through the mandibular canal in the mandible, providing sensory innervation to the lower teeth and surrounding tissues. It branches off from the mandibular nerve, a division of the trigeminal nerve (cranial nerve V). As it descends, it gives off the mylohyoid nerve and continues into the mandibular foramen, where it enters the bone to supply the molars and premolars. The nerve exits the mandible through the mental foramen as the mental nerve, innervating the chin and lower lip.

What kind of nerve is the trigeminal nerve?

Cranial Nerve 5 (trigeminal), division V3 contains a buccal nerve, a lingual nerve and an inferior alveolar nerve.

How many branches does the mandibular nerve have?

The mandibular nerve, which is the third division of the trigeminal nerve (CN V3), has several branches. It primarily divides into three main branches: the anterior trunk, which further gives rise to motor branches and sensory branches, and the posterior trunk, which provides sensory innervation. Key branches include the inferior alveolar nerve, lingual nerve, and buccal nerve, among others. Overall, the exact number of branches can vary, but it typically includes around five to six significant branches.

Which Nerve supplies the third molars?

Your third molars, or wisdom teeth as they are often called, are supplied by the inferior alveolar nerve (lower thirds) and the posterior superior alveolar nerve (upper thirds), which are branches of the Trigeminal (5th cranial) nerve.

Are cranial nerves motor or sensory?

sensory nerve

Does the peripheral nervous system have sensory nerve cells and motor nerve cells.?

Yes, the peripheral nervous system has both sensory and motor nerve cells

Can a nerve fibre and nerve both carry sensory and motor impulse Why?

Yes, a nerve fiber can carry both sensory and motor impulses, depending on the type of nerve. A mixed nerve contains both sensory (afferent) and motor (efferent) fibers, allowing it to transmit signals in both directions: sensory information from the body to the central nervous system and motor commands from the central nervous system to the muscles. However, individual nerve fibers typically specialize in either sensory or motor functions.

Are the spinal nerve both sensory and motor?

motor

What are pulpal reaction to local anesthesia?

The most commonly used local anesthetic is lidocaine (also called xylocaine or lignocaine), a modern replacement for novocaine and procaine. Its half-life in the body is about 1.5-2 hours. Other local anesthetics in current use include articaine, septocaine, marcaine (a long-acting anesthetic), and mepivacaine. A combination of these may be used depending on the situation. Also, most agents come in two forms: with and without epinephrine. The most common technique, effective for the lower teeth and jaw, is inferior alveolar nerve anesthesia. An injection blocks sensation in the inferior alveolar nerve, which runs from the angle of the mandible down the medial aspect of the mandible, innervating the lower teeth, lower lip, chin, and tongue. The inferior alveolar nerve probably is anesthetized more often than any other nerve in the body. To anesthetize this nerve, the dentist inserts the needle somewhat posterior to the patient's last molar. Several nondental nerves are usually anesthetized during an inferior alveolar block. Themental nerve, which supplies cutaneous innervation to the anterior lip and chin, is a distal branch of the inferior alveolar nerve. When the inferior alveolar nerve is blocked, the mental nerve is blocked also, resulting in a numb lip and chin. Nerves lying near the point where the inferior alveolar nerve enters the mandible often are also anesthetized during inferior alveolar anesthesia. For example, the lingual nerve can be anesthetized to produce a numb tongue. The facial nerve lies some distance from the inferior alveolar nerve, but in rare cases anesthetic can diffuse far enough posteriorly to anesthetize that nerve. The result is a temporary facial palsy (paralysis or paresis), with the injected side of the face drooping because of flaccid muscles, which disappears when the anesthesia wears off. If the facial nerve is cut by an improperly inserted needle, permanent facial palsy may occur.
