According to the myogenic hypothesis of renal autoregulation, the afferent arterioles contract in response to stretch induced by
NO release
Noradrenaline release
Opening of Ca2+ channels
Adenosine release
According to the myogenic hypothesis of renal autoregulation, the afferent arterioles contract in response to stretch by the opening of Ca2+ channels, whereas, tubuloglomerular feedback is due to the opening of ligand-gated Ca2+ channels by adenosine.
