Feedback Inhibition00:46

Feedback Inhibition

53.9K
Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Feedback Loops

57.5K
In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

What is a Sensory System?

93.3K
Sensory systems detect stimuli—such as light and sound waves—and transduce them into neural signals that can be interpreted by the nervous system. In addition to external stimuli detected by the senses, some sensory systems detect internal stimuli—such as the proprioceptors in muscles and tendons that send feedback about limb position.

概括

在Takotsubo综合征中QT间隔延长虽然令人担忧,但并没有显著影响患者的预后. 这一发现表明,这种心脏特征虽然令人担忧,但并不是塔科苏博综合征患者不良结果的主要预测因素.
