12 Questions
What is the main function of acetylcholine (ACh) in the body?
It is involved in the action of muscles, learning, and memory.
What is the role of GABA in the brain?
GABA is a neurotransmitter that helps control the precision of signals between neurons.
Which of the following is true about the number of neurotransmitters in the brain?
The precise number of neurotransmitters that exist is unknown, but scientists have identified more than 100 in the brain alone.
What is the effect of the black widow spider's venom on acetylcholine (ACh)?
The venom causes ACh to be released in excess, leading to violent muscle spasms.
How do some medications used to treat Alzheimer's disease work?

What can substances like drugs do in relation to receptor sites?
They fit into receptor sites and produce various effects
How many types of neurotransmitters do most neurons secrete?
Only one type
What is the primary way that the venom of the black widow spider harms?
By disturbing neurotransmission
