Messages move from one ____ to another along threadlike branches.
A
neuron
B
vein
C
artery
Explanation: 

Detailed explanation-1: -The transfer of information from neuron to neuron takes place through the release of chemical substances into the space between the axon and the dendrites. These chemicals are called neurotransmitters, and the process is called neurotransmission. The space between the axon and the dendrites is called the synapse.

Detailed explanation-2: -Interneurons. As the name suggests, interneurons are the ones in between-they connect spinal motor and sensory neurons. As well as transferring signals between sensory and motor neurons, interneurons can also communicate with each other, forming circuits of various complexity.

Detailed explanation-3: -Neurons communicate with each other via electrical events called ‘action potentials’ and chemical neurotransmitters. At the junction between two neurons (synapse), an action potential causes neuron A to release a chemical neurotransmitter.

Detailed explanation-4: -An axon is a long, hair-like extension of a nerve cell that carries a message to another nerve cell. Dendrites are thread-like extensions of the cytoplasm of a neuron that receive signals from other neurons.
