Neurons transmit signals to the central nervous system. The brain processes this information to initiate a response. Two neurons communicate with each other through the ( axon , dendrite, synapse) . The ( cerebrospinal cord, glial cell, neurotransmitter) is released at the site to initiate action potential and carry the signal through the body.
Answer:
synapse
neurotransmitter
Explanation:
Neurons are the basic units for the transmission of signals to the central nervous system. The two neurons are connected through the syanpse. Synapse is the space or junction between two nerve cells, or neurons.
The neuron receives signals through dendrites and two neurons communicate with each other through a chemical called neurotransmitter, which is released at the end of a nerve fibre and carry the signal through the body.
Hence, the correct answers are synapse and neurotransmitter.

There have be found some fossils of ancient remains over the years. What the fossils from Atapuerca revealed about the hominins living in Europe at this time is below:
- The Skull is known to show Interbreeding that took place with neandertals and their relatively healthy population.
- The Fragment shows that there was a possibility of cannibalism in that area.
It shows that possible cannibalism took place as there were Cutmarks on various hominin bones found at Atapuerca mirror.
The relatively healthy population was found out through the study of the dentition of the Atapuerca hominins by anthropologists. It gave them a view into their diet and overall health.
The interbreeding with the Neandertals was shown through the Nuclear DNA that was gotten from bones and teeth of bones found at Sima de los Huesos
