一.消化道平滑肌的一般生理特性有那些? 消化道平滑肌有肌肉组织的共同特性,如兴奋性、传导性及收缩性等,但这些特性的表现又具有自己的特点。1.兴奋性较低,收缩缓慢。消化道平滑肌与骨骼肌相比,其收缩需要较长时间才能发动起来,恢复到原来的长度也很慢。它的这一特性与其缓慢、持续性的运动是一致的,也和食物的消化过程相适应。2.富有伸展性。消化道平滑肌能根据需要而作很
A general gastrointestinal smooth muscle physiological characteristics of those? Muscle tissue gastrointestinal smooth muscle common features, such as excitability, conductivity and contractility, but these characteristics of the performance and has its own characteristics. 1. Low excitability, slow contraction. Compared with skeletal muscle, gastrointestinal smooth muscle contraction takes a long time to start up, and the original length is very slow. Its characteristic is consistent with its slow, continuous movement and also with the digestion of food. Scalability Gastrointestinal smooth muscle can be made as needed
