Answer:
Explanation:
I think it is: acetylcholine (neurotransmitter) - motor neuron - contract
second question: diffusion because of opening of ca2+ channels
The term Neurotransmitter describes the chemical substances that make it possible for messages to cross from the synapse of a neuron to the target receptor.
<h3>What are Neurotransmitters?</h3>
- Neurotransmitters are endogenous chemicals that allow neurons to communicate with each other throughout the body.
- Chemical synaptic transmission is primarily through the release of neurotransmitters from presynaptic neural cells to postsynaptic receptors.
- There are a number of neurotransmitters used by the body for different functions, including acetylcholine, norepinephrine, glutamate, GABA, glycine, dopamine, and serotonin.
- Glutamate is the principal excitatory neurotransmitter used in the brain.
- GABA and Glycine serve as the major inhibitory neurotransmitters.
