The latus rectum of a parabola is a segment with endpoints on the parabola passing through the focus and parallel to the directrix.
The word latus rectum came from Latin, latus means 'side' or line and rectum means 'straight'.
A parabola opens downward when the coefficient of its ( x^2 ) term (denoted as ( a )) is negative. This means that the vertex of the parabola is the highest point on the graph. Conversely, if ( a ) is positive, the parabola opens upward.
When the coefficient of the y term ( a ) in the equation of a parabola is negative, the parabola opens downward. This means that its vertex is the highest point on the graph. Conversely, if ( a ) were positive, the parabola would open upward.

The vertex of this parabola is at -2 -3 When the y-value is -2 the x-value is -5. The coefficient of the squared term in the parabola's equation is -3.
In medical terms, per means via or through, so per rectum means through the rectum, and per vagina means via the vagina.
