What is the mechanism responsible for the intrinsic property of the arteriolar smooth muscle to contract when previously stretched?

The myogenic theory explains the intrinsic property of the arteriolar smooth muscle to contract when previously stretched.
When the blood pressure increases, the afferent arteriole stretches, causing the contraction of its smooth muscle and increasing resistance.
The myogenic theory is one of the mechanisms responsible for the autoregulation of the glomerular filtration rate.
