sections and retractions

If there exists morphism $g:B\rightarrow A$ such that $g\circ f=1_{A}$ then $f$ is called retractable and $g$ is called retraction of $f$.

If there exists morphism $g:B\rightarrow A$ such that $f\circ g=1_{B}$ then $f$ is called sectionable and $g$ is called section of $f$.
