Entry Point
An entry point is a pseudostate that marks the point of entry to the region in a state machine in which it is enclosed. It has a single outgoing transition to a vertex in the same region. An entry point can only be defined for the top most regions of a state machine and not for regions owned by other regions. Each topmost region of a state machine can contain one (and only one) entry point.
Explanation
A state machine can contain regions and the topmost of these regions can each contain a single entry point. An entry point is used to indicate the starting point for the region and has a single outgoing transition (line) to another vertex in the region of the state machine in which it is enclosed.
An exit point is related to an entry point because they are paired elements and typically appear together, one used to mark the points of exit and the other marking the single point of entry.
