Here's why:
* Prepositional phrase: A prepositional phrase starts with a preposition (in this case, "from") and ends with an object.
* Preposition: The preposition "from" indicates a starting point or origin.
* Object: The word following the preposition is the object of the preposition. In this case, it's "head."
