What passes from the neuron to the muscle cells and what effect does it produce?
Acetylcholine (ACh) is the neurotransmitter that passes from neuron to muscle cells and it causes the Na/K channels to open allowing Na+ to flow into the cell triggering an action potential.
What molecule is released from synaptic vesicles and serves as the means of communication from one neuron to the next or from a neuron to an effector cell?
Neurotransmitter
A molecule that is released from synaptic vesicles and serves as the means of communication from one neuron to the next or from a neuron to an effector cell?
Neurotransmitter.
What substance crosses the gap between a neuron and a muscle fiber?
This substance is called as neurotransmitter. Here it is acetylcholine.
Why is it that the electrical impulse cannot pass from neuron the muscle cell?
There is a space (synapsis) between the neuron and the muscle cell. The electrical impulse can not pass over that. Chemical neurotransmitters are manufactured by neurons in the soma, then stored in little bundles called synaptic vesicles and transferred to the synapses. The release of the neurotransmitter is required for a nerve to simulate the muscle. This is what crosses the space.

Transferring messages from a motor neuron to a leg muscle requires the neurotransmitter known as?
acetylcholine

Neurotransmitter
Trace how a message is passed from one neuron to another?
A neuron sends a message, or neurotransmitter, to the muscle cell to tell it what to do. To get the message, the receiving cell must have a receptor. Oddly, the unstable protein rapsyn is responsible for anchoring the receptor so it's properly positioned to catch the message.

What a neurotransmitter is?
A neurotransmitter is a chemical or peptide in synapses, usually between neurons, a neuron and muscle or a neuron and other organ. The neurotransmitter transmits information to and from and within the brain. When a neurotransmitter is released from the presynaptic cell in response to depolarization of the cell by an action potential, it diffuses across the synaptic cleft and binds a receptor or ligand-gated ion channel on the postsynaptic cell. Binding on the postsynaptic cell alters the resting potential of the postsynaptic cell in either an inhibitory or excitatory manner, making the cell less susceptible or more susceptible (respectively) to an action potential. Examples include, but are not limited to, acetylcholine, GABA, noradrenaline, serotonin and dopamine.
What are functions of synaptic junction?
To "connect" two neurons, (or a neuron and a muscle cell), by providing a space between an axon terminal of one neuron and a dendrite of another neuron (or a muscle cell), so neurotransmitters that are released by an axon terminal can diffuse across that space to reach the dendrite (or muscle cell) and either initiate the possibility of the second neuron to fire or cause a muscle cell to contract.
What part of neuron releases neurotransmitter my choices are axon axon terminal dendrite myelin sheath or cell body?
The neurotransmitter is released from the axon terminal.
What is a presynaptic neuron?
a neuron from the axon terminal of which an electrical impulse is transmitted across a synaptic cleft to the cell body or one or more dendrites of a postsynaptic neuron by the release of a chemical neurotransmitter.
What kind of stimulus (electrical or chemical) travels from the motor neuron to skeletal muscle?
This is done through a neurotransmitter. So the answer is chemical.
