  3. symphysis menti from mental protuberance as triangualr elevation having mental tubercle on each side. • Lateral to symphysis menti there is mental foramen which transmit mental N. & Vesseles • thick ridge called oblique line.

  4. Inside the body of Md. There is Md. Canal , the entrance of this canal lies on inner surface of ramus & is called Mandibualr foramen.

  5. Upper border of body of Md. Termed alveolar process which carries the socket or alveoli of the teeth. • Lower border of body of Md. Termed base of Md. That gives attachment with …….. Ms .

  6. The ramus of Md. Has 2 process projecting from upper border: The condylar process post. Coronoid process ant. • The condylar process comprise head & neck of Md. • Md. Notch lies between 2 process Note: • The front neck of Md. Give insertion to lateral pterygoid Ms. • The coronoid process give insertion to temporalis Ms. • The lateral surface of ramus of Md. Give insertion to masseter Ms. & it’s cover by parotid gland .

  7. The medial border of foramen is projecting to form lingula which sphenomandibualr ligament attachment, • just behind lingula, there is mylohyoid groove that lodges mylohyoid N.& V.
