A chemical produced by neurons that carries messages to other neurons
A
myelin sheath
B
neurotransmitter
C
axon
D
axon terminal
Explanation: 

Detailed explanation-1: -A neuron sending a signal (i.e., a presynaptic neuron) releases a chemical called a neurotransmitter, which binds to a receptor on the surface of the receiving (i.e., postsynaptic) neuron. Neurotransmitters are released from presynaptic terminals, which may branch to communicate with several postsynaptic neurons.

Detailed explanation-2: -Neurotransmitters are chemical messengers that your body can’t function without. Their job is to carry chemical signals (“messages”) from one neuron (nerve cell) to the next target cell.

Detailed explanation-3: -Neurons communicate via both electrical and chemical signals. A neuron receives input from other neurons and, if this input is strong enough, the neuron will send the signal to downstream neurons. Transmission of a signal between neurons is generally carried by a chemical called a neurotransmitter.

Detailed explanation-4: -The messages carried by neurons are called nerve impulses. Nerve impulses can travel very quickly because they are electrical impulses. Neurons are usually classified based on the role they play in the body. Two main types of neurons are sensory neurons and motor neurons.
