In NCAA regulations, what are "bylaws" primarily used for?

Bylaws within NCAA regulations serve primarily to govern the activities of member institutions. They provide a structured framework that dictates how these institutions operate within the NCAA's guidelines. This includes rules on competition, recruitment, scholarships, and conduct, ensuring that member institutions adhere to the same standards and practices. By establishing clear bylaws, the NCAA maintains fairness and integrity in college athletics, allowing schools to compete under uniform rules.

While other options address important aspects of NCAA's functions, such as outlining membership eligibility and defining the mission, they are more specific facets rather than the overarching goal of bylaws. The penalties for violations also relate to enforcement measures rather than the broader regulatory function that bylaws serve in guiding members' activities. Hence, the primary role of bylaws is to govern how member institutions interact in competitions and manage their athletic programs comprehensively.
