Introduction: Neurons are specialized cells that help collect external information, analyse the information and respond to it. Neurons make up a large signaling network, called the nervous system, in the body.

Explanation of Solution
Neuron consists of three major regions: a cell body, the dendrites, and an axon. Dendrites receive signals to the brain called impulses and carry the impulses into the cell body. An axon carries nerve impulses from the cell body to other muscles and neurons.
A reflex arc is a nerve pathway comprised of a sensory neuron, a motor neuron and an interneuron.

Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?arrow_forward
