Blockade of light-sensitive conductance in hyperpolarizing photoreceptors of the scallop.
These demarcate the so-called "scallops", or commissural leaflets.
Both arteries were removed with their respective sinuses as scallops for translocation.
Either removal of a large scallop or further dissection is necessary in these circumstances.
The same care is needed, therefore, with dissection and removal of a large aortic scallop.
