n. [解剖] 逼尿肌;壓出器
Methods:Bladder detrusor urinae of rat were suspended in smooth muscle chambers and contractile activity were observed.
方法:将肌條置于離體平滑肌灌流肌槽内,用生理記錄儀記錄肌條的收縮活動。
These may act in both directions and either dampen (inhibit) or exaggerate (stimulate) the desired lumbar to sacral detrusor activation.
這些效應可能在兩個方向上都起作用,或者減弱(抑制)、或者誇大(刺激)所期望的通過腰-骶神經對逼尿肌的激活作用。
Conclusion detrusor instability secondary to BPH obstruction is related to the decrease of cholinergic innervation density in the detrusor muscles.
結論BPH梗阻性逼尿肌不穩定與逼尿肌膽堿能神經密度降低(去神經)程度有關。
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,應用逆轉錄-聚合酶鍊反應(RT - PCR)方法檢測DI及逼尿肌穩定(DS)大鼠逼尿肌組織IP3R亞型變化。
Objective To observe the changes of bladder detrusor excitability and autorhthmicity in experimental rats with non-insulin dependent diabetes mellitus(NIDDM).
目的研究非胰島素依賴型糖尿病(NIDDM)大鼠的逼尿肌興奮性及自律性的變化。
detrusor(逼尿肌)是膀胱壁的主要肌肉層,負責控制排尿過程中的膀胱收縮與排空。作為平滑肌組織,它以網狀結構交織排列,形成膀胱的肌性外壁,在儲尿和排尿階段發揮關鍵生理作用。
逼尿肌由三層平滑肌纖維構成(外層縱行、中層環行、内層縱行),其收縮力受自主神經系統調節:
逼尿肌功能障礙可能導緻多種泌尿系統疾病:
臨床通過尿動力學檢查評估逼尿肌功能,治療方案包括:
詞源小知識:術語“detrusor”源自拉丁語“detrudere”(意為“推壓”),形象描述其排尿時擠壓膀胱的動作特性(來源:牛津醫學詞源詞典)Oxford Reference。
detrusor 是解剖學和醫學領域的專業術語,主要含義如下:
