This video explains the origin, insertion, nerve supply, and actions of the muscles of mastication, in addition to the origin, course, and branches of the mandibular nerve (including MCQ, practical, and interactive questions). * 𝐂𝐡𝐚𝐩𝐭𝐞𝐫𝐬 (𝐭𝐢𝐦𝐞𝐬𝐭𝐚𝐦𝐩𝐬) الفصول (الطوابع الزمنية) 00:00 - Intro (مقدمة) 00:21 - Content (المحتوى) 01:07 - Definition of temporal & infratemporal regions 03:03 - Boundaries of the infratemporal fossa 04:17 - Contents of the infratemporal fossa 05:43 - Muscles of mastication 11:10 - Masseter muscle 16:30 - Temporalis muscle 21:01 - Medial pterygoid muscle 28:36 - Lateral pterygoid muscle 40:32 - Applied anatomy 49:17 - Mandibular nerve 1:00:13 - Practical questions 1:04:15 - Interactive questions * 𝐄𝐱𝐜𝐞𝐩𝐭𝐢𝐨𝐧 𝐫𝐮𝐥𝐞𝐬 𝐢𝐧 𝐢𝐧𝐟𝐫𝐚𝐭𝐞𝐦𝐩𝐨𝐫𝐚𝐥 𝐟𝐨𝐬𝐬𝐚: 1. All the muscles of mastication cause protraction EXCEPT the posterior fibers of temporalis cause retraction. 2. All of them cause elevation EXCEPT lateral pterygoid causes depression. 3. All the muscles are supplied by the anterior division of the mandibular nerve EXCEPT medial pterygoid which is supplied by the main trunk of the mandibular nerve. * 𝐃𝐞𝐭𝐞𝐜𝐭𝐢𝐨𝐧 𝐨𝐟 𝐭𝐡𝐞 𝐬𝐢𝐝𝐞 𝐨𝐟 𝐩𝐚𝐫𝐚𝐥𝐲𝐬𝐢𝐬: - Injury of the mandibular nerve leads to paralysis of the muscles of the mastication. - This paralysis is manifested by the deviation of the mandible to the paralyzed side. * 𝐈𝐧𝐟𝐞𝐫𝐢𝐨𝐫 𝐚𝐥𝐯𝐞𝐨𝐥𝐚𝐫 𝐧𝐞𝐫𝐯𝐞 𝐛𝐥𝐨𝐜𝐤: - It involves the injection of a local anesthetic solution near the area of the mandibular foramen and the entry of the nerve into the inferior alveolar canal. - This anesthetic technique is widely used in routine dental practice as it facilitates multiple surgical procedures. - The most important clinical landmarks used in the location of the inferior alveolar nerve block are the coronoid notch and the pterygomandibular raphe. The preferred site of needle insertion lies between these two landmarks and the point of insertion is determined by simple measurements. * 𝐌𝐂𝐐: 1. During an examination of the movements of the mandible the dentist observed that the patient cannot protrude the mandible. Which of the following muscles were paralyzed on both sides? A. Anterior belly of digastric B. Geniohyoid C. Genioglossus D. Lateral pterygoid 2. Which of the following muscles can produce retraction of the mandible? A. Temporalis B. Medial pterygoid C. Masseter D. Lateral pterygoid 3. Nerve to medial pterygoid arises from which part of the mandibular nerve? A. Trunk B. Anterior division C. Posterior division D. Its inferior alveolar branch 4. Injury of the inferior alveolar nerve at its origin will lead to paralysis of which of the following muscles? A. Anterior belly of digastric B. Posterior belly of digastric C. Stylohyoid D. Thyrohyoid 5. Which of the following is a branch from the trunk of the mandibular nerve? A. Deep temporal nerve B. Nervous spinosus C. Buccal nerve D. Lingual nerve 6. Which of the following is true regarding the mandibular nerve? A. It supplies the teeth of the upper jaw B. It passes through the foramen lacerum C. It supplies all muscles of mastication D. Superior alveolar nerve is one of its branches 7. Which of the following muscles opens the jaw? A. Buccinator B. Lateral pterygoid C. Masseter D.
