Answer:
caused acetylcholine to be continuously released by the motor neurons.
Explanation:
The venom of black widow spider is neurotoxic and contains α-latrotoxin. This toxin binds to the surface receptors of neurosecretory PC12 cells and vertebrate synapses and activates the release of the neurotransmitter acetylcholine.
Acetylcholine is the neurotransmitter which plays important role in muscle contraction so the toxin allow the continuous release of the neurotransmitter which cause contraction of smooth muscle in airways and other muscle in the body and cause breathing difficulties and muscle spasms.

It may help if you and your partner still hold that trust and bond you had created with one another and as married you tend to trust each other more and be more open witch in my opinion a female likes more if the male is honest. If they both respect one another and take care of each others responsibilities then there will be no problems
(Hopefully this helped)
