To curb is to restrain as if with reins: "As a teacher he was rather dull. He curbed his own enthusiasms, finding that they distracted his attention" (E.M. Forster).
Check implies arresting or stopping, often suddenly: "Knowing that Lily disliked to be caressed, she had long ago learned to check her demonstrative impulses toward her friend" (Edith Wharton).
To bridle is often to hold in or govern one's emotions or passions: I tried hard to bridle my anger. Inhibit usually connotes a check on one's actions, thoughts, or emotions: A fear of strangers inhibited his ability to travel.
