What type of movement does the frenulum limit?

The frenulum plays a key role in the structure and function of various body parts, particularly in the oral cavity, where it connects the tongue to the floor of the mouth or the lip to the gums. This connective tissue restricts how far the tongue can move, controlling its range of motion.

For instance, a well-developed frenulum helps maintain the position and movement of the tongue during speaking and swallowing. If the frenulum is too tight, a condition known as ankyloglossia, it can significantly limit the range of motion of the tongue, potentially affecting speech clarity and feeding.

Understanding the role of the frenulum in limiting movement is essential, as it helps clarify its function in the body. The other choices—growth, flexibility, and strength—focus on different aspects of physical development or abilities and do not accurately capture the primary function of the frenulum related to mobility.
