n. [解剖] 逼尿肌;压出器
Methods:Bladder detrusor urinae of rat were suspended in smooth muscle chambers and contractile activity were observed.
方法:将肌条置于离体平滑肌灌流肌槽内,用生理记录仪记录肌条的收缩活动。
These may act in both directions and either dampen (inhibit) or exaggerate (stimulate) the desired lumbar to sacral detrusor activation.
这些效应可能在两个方向上都起作用,或者减弱(抑制)、或者夸大(刺激)所期望的通过腰-骶神经对逼尿肌的激活作用。
Conclusion detrusor instability secondary to BPH obstruction is related to the decrease of cholinergic innervation density in the detrusor muscles.
结论BPH梗阻性逼尿肌不稳定与逼尿肌胆碱能神经密度降低(去神经)程度有关。
Methods: To set up the model of DI rats, the IP3R isoforms expressions of detrusor tissue in DI rats and ds rats were detected by RT-PCR technique.
方法:建立DI大鼠模型,应用逆转录-聚合酶链反应(RT - PCR)方法检测DI及逼尿肌稳定(DS)大鼠逼尿肌组织IP3R亚型变化。
Objective To observe the changes of bladder detrusor excitability and autorhthmicity in experimental rats with non-insulin dependent diabetes mellitus(NIDDM).
目的研究非胰岛素依赖型糖尿病(NIDDM)大鼠的逼尿肌兴奋性及自律性的变化。
detrusor(逼尿肌)是膀胱壁的主要肌肉层,负责控制排尿过程中的膀胱收缩与排空。作为平滑肌组织,它以网状结构交织排列,形成膀胱的肌性外壁,在储尿和排尿阶段发挥关键生理作用。
逼尿肌由三层平滑肌纤维构成(外层纵行、中层环行、内层纵行),其收缩力受自主神经系统调节:
逼尿肌功能障碍可能导致多种泌尿系统疾病:
临床通过尿动力学检查评估逼尿肌功能,治疗方案包括:
词源小知识:术语“detrusor”源自拉丁语“detrudere”(意为“推压”),形象描述其排尿时挤压膀胱的动作特性(来源:牛津医学词源词典)Oxford Reference。
detrusor 是解剖学和医学领域的专业术语,主要含义如下:
