This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Physiology
In a neuron, graded electrogenesis occurs at: 
Select and explain. 
A. Soma-dendritic zone, B. Initial segment, C. Axon, D. Nerve ending
A: Soma-dendritic zone
Answer: A: Soma-dendritic zone 
Explanation: Graded electrogenesis is local potential generation of which occurs in dendrite or, soma.
Neurons generally have some important zones: 

A receptor, or dendritic zone, where multiple local potential generated by synaptic connections are integrated;
A site where propagated action potentials are generated (the initial segment in spinal motor neurons, the initial node of Ranvier in cutaneous sensory neurons).
