Final answer:
The head of the municipal government is usually called the mayor or reeve. They are responsible for executive functions in a mayor-council system or preside over the council in a council-manager system.
Step-by-step explanation:
In a municipal government, the head is commonly known as the mayor or reeve. The specific title may vary depending on the country or region. In a mayor-council system, both the mayor and members of the city council are elected by voters, with the mayor responsible for executive functions and the council handling legislative functions. In a council-manager system, the city council appoints a city manager to oversee administrative tasks while the mayor presides over the council. The city manager is typically an engineer or businessman with expertise in city operations.
