【摘要】：目的：通過對(duì)人豎脊肌的肌構(gòu)筑和肌梭分布的研究。進(jìn)一步探討豎脊肌的形態(tài)學(xué)特點(diǎn),為深入研究豎脊肌在軀干運(yùn)動(dòng)中的作用提供形態(tài)學(xué)依據(jù),并為肌的臨床應(yīng)用提供參考數(shù)據(jù)。 方法：1.用經(jīng)甲醛固定1年以上的成人尸體6具,完整取下兩側(cè)的豎脊肌,采用大體解剖法觀察肌內(nèi)腱板的位置、形態(tài)、數(shù)量,肌束的行走方向與肌內(nèi)腱板的位置關(guān)系；2.成人尸體6具,用肌構(gòu)筑法測量豎直肌的肌重、肌長、肌纖維長、生理橫切面積等肌構(gòu)筑學(xué)指數(shù),探討其構(gòu)筑學(xué)特征；3.用甲醛固定的成人尸體5具,共10側(cè),分別在棘肌、最長肌、髂肋肌的肌腹中部取材,行組織學(xué)HE染色后,采用體視學(xué)方法進(jìn)行肌梭密度的研究。 結(jié)果：1.大體解剖研究第一腰椎棘突以上平面,棘肌、最長肌、髂肋肌三部分可通過兩條縱行淺溝分離。棘肌內(nèi)有數(shù)條長肌腱連接大量短肌束,形成羽肌。最長肌肌部內(nèi)有多個(gè)寬扁的肌內(nèi)腱板,大量肌纖維附著于腱板形成多羽肌,胸部以上最長肌的肌纖維長,形成半羽肌。髂肋肌肌有分層,肌淺面是長肌纖維,肌深面以短肌纖維占優(yōu)勢,肌束背腹走向,形成羽肌。2.肌構(gòu)筑學(xué)特征：①肌重：豎直肌總重量(371.41±44.10)g；棘肌(61.16±13.26)g,最長肌(197.88±16.53)g,髂肋肌(113.29±17.51)g。②肌長：棘肌(52.86±2.35)cm,最長肌(57.51±2.78)cm,髂肋肌(52.55±3.32)cm。③肌纖維長：棘肌(5.75±0.78)cm,最長肌(11.85±1.58)cm,髂肋肌(11.78±1.30)cm。④羽狀角：髂肋肌,最長肌,棘肌均為10。。⑤生理橫切面積：棘肌(8.68±2.60)cm2,最長肌(13.41±1.59)cm2,髂肋肌(7.73±1.48)cm2。3.肌梭分布：棘肌肌梭密度為(5.43±3.46)個(gè)/cm3,肌梭指數(shù)為(5.14±2.27)個(gè)/g；最長肌肌梭密度為(13.22±2.32)個(gè)/cm3,肌梭指數(shù)為(12.51±2.16)個(gè)/g；髂肋肌肌梭密度為(12.07±2.51)個(gè)/cm3,肌梭指數(shù)為(11.42±1.17)個(gè)/g。 結(jié)論：1.豎脊肌三部分肌中,棘肌是由短肌束構(gòu)成的羽肌,最長肌和髂肋肌的下1/3段是短肌束構(gòu)成的多羽肌,肌上2/3段,是由長肌束構(gòu)成的半羽肌。 2.棘肌的CSA/MW在三塊肌中比值最大,傾向于力量型構(gòu)筑。最長肌和髂肋肌兼具力量型與速度型構(gòu)筑學(xué)特征,具有提供肌力的潛力,也服務(wù)于速度運(yùn)動(dòng)。 3.豎脊肌肌梭密度高對(duì)維持脊柱的穩(wěn)定性有重要作用。
[Abstract]:Objective: to study the muscle architecture and muscle spindle distribution of human erector spinal muscle.In order to provide morphological basis for further study on the role of erector spinal muscle in trunk movement and to provide reference data for clinical application of the muscle, the morphological characteristics of erector spinal muscle were further discussed.Method 1: 1.Six adult cadavers were fixed with formaldehyde for more than one year. The position, shape, quantity, walking direction of muscle bundle and the position of intramuscular tendon plate were observed by gross dissection method.Six adult cadavers were used to measure the muscle weight, muscle length, muscle fiber length and physiological cross sectional area of vertical rectus muscle.Five adult cadavers fixed with formaldehyde were collected from the middle of the muscle abdomen of spinalis longus longus and iliac rib respectively. The density of muscle spindle was studied by stereological method after HE staining.The result is 1: 1.Gross anatomical study of the first lumbar vertebrae above the spinous process, the spinous muscle, the longest muscle, and the iliac rib muscle can be separated by two longitudinal superficial sulcus.There are several long tendons in the spinous muscle connecting a large number of short muscle bundles to form the pinnacle.There are several broad flat intramuscular tendon plates in the longissimus muscle. A large number of muscle fibers are attached to the tendon plate to form polypinnae. The muscle fibers of the longest muscle above the chest are long and form semi-pinnae.The iliac rib muscle is stratified, the superficial surface is the longus muscle fiber, the deep surface is dominated by the short muscle fiber, and the dorsal ventral direction of the muscle bundle forms the pinnar muscle. 2.鑲屾瀯絳戝鐗瑰緛:鈶犺倢閲，
