面部表情肌群 |
枕額肌 |
(1) 提瞼揚眉,並形成額紋 ( Raises eyebrows, wrinkles for h ead ) |
顏面 |
口輪匝肌 |
緊閉口 ( Narrows orifice of mouth ) ,獗起嘴唇 ( purses lips ) 、吹口哨動作;與頰肌共同收縮,可坐吸吮動作 ( puckers lip edges) |
||
眼輪匝肌 |
閉合眼瞼( Closes eyelids) 、擴張淚囊 |
||
咀嚼肌 |
咬肌 |
上提下頜骨(elevates mandible) |
三叉 |
顳肌 |
上提下頜骨,並可將前移的下頜骨向後拉回 (elevates and retracts mandible) |
||
翼內肌 |
上提下頜骨,閉口動作;若與翼外肌協同作用下,使下頜骨作研磨動作 ( Elevates the mandible and assits in closing the jaw . Aassits the lateral pterygoids in moving the jaw side-to-side) |
||
翼外肌 |
雙側同時收縮時,使下頜骨前移,幫助張口 ( Depresses and protracts mandible to open mouth . Pulls forward cartilage of joint during opening of mouth. Aids in chewing) |
( 註 ) 咬肌、顳肌和翼內肌在收縮時能上提下頜骨 ( 閉口肌 ) ;兩側翼外肌同時收縮,使下頜骨向前 ( 張口肌 ) 。 翼內肌與翼外肌皆協助下頜骨( mandible )移向對側 ( contralateral side ) 。
- 咬肌( masseter muscle )
- 翼外肌( lateral pterygoid muscle )
- 頰肌( buccinator muscle )
- 顴大肌( zygomatic major muscle )
<100-2-20> 下列有關顳下頜關節( temporomandibular joint )之敘述,何者錯誤?
- 翼內肌( medial pterygoid muscle )協助張口
- 翼內肌與翼外肌皆協助將下頜骨( mandible )移向對側邊( contralateral side )
- 部分翼外肌附著於顳下頜關節之關節盤( articular disc )
- 顳下頜關節位於下頜窩( mandibular fossa )及下頜骨之髁突( condylar process )之間
