Final answer:
The connection that is NOT a neuroeffector junction is the one between a neuron and another neuron (E), as this is typically known as a synapse. Neuroeffector junctions are specific to neuronal connections with muscle fibers or glands to facilitate a response.
Step-by-step explanation:
The neuroeffector junction that is NOT included in the options provided is the junction between a neuron and a neuron (E), which is instead called a synapse. Neuroeffector junctions are the interfaces where neurons connect with other types of cells such as muscle fibers or glandular cells to bring about an effect, like inducing muscle contraction or gland secretion.
When it comes to neuromuscular junctions, motor neuron axons release acetylcholine at the motor end-plate of the sarcolemma of muscle fibers, leading to muscle contraction. Similarly, neurons can connect with smooth muscle cells, endocrine glands, and exocrine glands to produce different types of body responses.
