Uh, is it corticotropin-releasing hormone? I hope Google isn't wrong

That's what it is stimulated by. I was actually looking for

proopimelanocortin

Your turn!

I've mostly heard it being called the lacrimal caruncle, but I've seen your answer as a synonym as well. Correct!

Your turn.

Choose the correct answers:
In the dark, cGMP gated cation channels of a photoreceptor are (1)[open/closed], causing the photoreceptor to (2)[depolarize/hyperpolarize]. This causes (3) [Ca++/Na+] channels to (4) [open/close] at the synaptic terminal of the photoreceptor. Neurotransmitter (5) [is/is not] released into the synaptic cleft, causing (6) [IPSPs/EPSPs] in the bipolar cell, and thus (7) [depolarizing/hyperpolarizing] the bipolar cell. At the synaptic terminal of the bipolar cell, voltage gated (8)[Ca++/Na+] channels (9)[open/close], and neurotransmitter (10)[is/is not] released into the synaptic cleft. As a result, EPSPs (11)[are/are not] generated in the ganglion cell, and an action potential (12)[does/does not] propagate along the optic nerve.
Aaaah hope I'm not too confusing
