求翻译:在反射活动中,从刺激开始到效应器产生反应之间的时间叫做反射时。它包括刺激引起感受器兴奋,产生神经冲动;神经冲动在传入神经和传出神经上传导以及神经冲动引起效应器发生反应所消耗的时间外,还包括冲动在中枢的突触处传递所消耗的时间。后者比冲动在相应长度的神经纤维上传导所需的时间要长得多。因此,叫做中枢性延迟或突触性延迟。据测定,兴奋通过一个突触所需要的时间为0.3~0.5毫秒,由此可知,在反射中枢内通过的突触数越多,中枢性延迟的时间越长。是什么意思?

In reflex activity from the stimulus effect generated by the reaction time between when called reflection. It includes the stimulation of afferent inputs to produce nerve impulses; nerve impulse conduction in the afferent and efferent nerve impulses cause the effector to the time consumed by the rea

In reflection activities, from stimulating effectors started a reaction to the time between when you called reflections. It includes exciting cause feelings, excitement, and produce nerve impulses; at the incoming nerve impulses to the nerve and the nerve conduction, as well as nerve impulses cause

In the reflection activity, starts from the stimulation to the effector to have between time the response time named reflection.It causes the receptor including the stimulation to be excited, has the nerve impulse; The nerve impulse the conduction as well as the nerve impulse causes the effector in
