【摘要】 目的:探讨眼周围肌的构筑学特征并为临床应用提供解剖学资料。方法:对10具尸体的皱眉肌、降眉间肌、额肌和眼轮匝肌进行大体解剖、横切片HE染色、图像分析及肌构筑学研究。结果:(1)皱眉肌、降眉间肌、额肌和眼轮匝肌上、下部的肌重分别为(1.0±0.5)g、(1.2±0.4)g、(4.2±0.6)g和(3.2±0.8)g(、3.4±0.6)g,肌长分别为(24.2±0.7)mm、(27.8±1.1)mm、(62.0±0.9)mm和(40.5±1.2)mm、(41.7±0.8)mm,生理横切面积分别为(44.4±0.3)mm2(、44.2±0.6)mm2、(80.5±0.7)mm2和(81.9±0.4)mm2(、88.2±0.3)mm2;(2)皱眉肌、降眉间肌、额肌和眼轮匝肌上、下部的肌纤维直径分别为(29.6±0.5)μm(、20.3±0.8)μm(、32.4±0.6)μm和(27.5±0.4)μm、(25.8±0.4)μm,肌束横切面积分别为(2.69±0.032)×104μm2、(1.17±0.037)×104μm2(、1.38±0.039)×104μm2和(2.39±0.065)×104μm2(、2.42±0.076)×104μm2;(3)皱眉肌分横向型和斜向型,且以斜向型多见(70%)。结论:眼轮匝肌、皱眉肌、降眉间肌和额肌具有“速度型”设计的构筑特征,肌的收缩力量小。皱眉肌和额肌同时进行紧张性收缩。更多还原

【Abstract】 Objective:To investigate the architectural features of muscles around eyes and provide anatomic data for clinical application.Methods:The gross anatomy,HE stain of cross sections,analysis of pictures and study of muscular architecture were performed on corrugutor supercilii,procerus,frontalis,and orbicularis oculi in 10 cadavers.Results:(1)The muscle weight of corrugutor supercilii,procerus,frontalis,the upper part and inferior part of orbicularis oculi were(1.0±0.5) g,(1.2±0.4) g,(4.2±0.6) g,(3.2±0.8) g,(3.4±0.6) g respectively;their lengths were(24.2±(0.7)) mm,(27.8±1.1) mm,(62.0±0.9) mm,(40.5±1.2) mm and(41.7±0.8) mm respectively;their transverse areas were(44.4±0.3) mm2,(44.2±0.6) mm2,(80.5±0.7) mm2,(81.9±0.4) mm2 and(88.2±0.3)mm2 respectively.(2)The diameters of muscle fiber in corrugutor supercilii,procerus,frontalis,the upper and inferior part of orbicularis oculi were(29.6±0.5) μm,(20.3±0.8) μm,(32.4±0.6) μm,((27.5)±0.4) μm and(25.8±0.4) μm respectively;the transverse areas of these muscle bundle were(2.69±0.032)×104 μm2,(1.17±0.037)×104 μm2,((1.38)±0.039)×104 μm2,(2.39±0.065)×104 μm2 and(2.42±0.076)×104 μm2 respectively.(3)The corrugator supercilii muscle could be divided into transversal type and inclined type(70%).Conclusions:Corrugator supercilii muscle,procerus,frontalis and orbicularis oculi possess the architectural features of "velocity type" and small contraction forces.The corrugutor supercilii and frontalis have tonic contraction simultaneously.更多还原
