1. The plane of the lateral pterygoid muscle is the lateral boundary line of the endoscopic transnasal transantral approach.

2. Results: The amount of insulin in lateral pterygoid muscle in young growing rats enhanced after functional mandibular protrusion.

3. Conclusion The lateral pterygoid muscle, styloid process, pterygoid process and its medial, lateral pterygoid plate were important anatomical marks for CT imaging diagnosis.

4. The innervation of the medial pterygoid muscle can be divided into low branch(38 cases, 63%)and high branch types(22 cases, 37%).

5. Objective: To investigate the effect of insulin on the lateral pterygoid muscle after functional mandibular protrusion in rats.

6. The maximun binding changes of the acetylcholine receptor on rat lateral pterygoid muscle after the function mandibular advancement.

7. Objective : To study the distribution features of intramuscular nerves and spindles in human lateral pterygoid muscle.

8. Results The main masticatory muscles of miniature pigs include masseter muscle, temptory muscle, lateral pterygoid muscle, medial pterygoid muscle and zygomaticomandibular muscle.

9. And changes also had been taken place on the form and function of the lateral pterygoid muscle, articular disc and fovea.
