The Ability to Curl Your Tongue into a Tube Is

Question

The ability to curl your tongue into a tube is a genetic trait controlled by what muscle(s)?
A)Hyoglossus
B)Palatoglossus
C)Styloglossus
D)Intrinsic tongue muscles
E)Genioglossus

Accepted Answer

The intrinsic tongue muscles are responsible for shaping the tongue into different configurations. The ability to curl one's tongue into a tube is a result of the specific arrangement and strength of these muscles, which is determined by genetics. Hyoglossus, Palatoglossus, Styloglossus, and Genioglossus are all extrinsic tongue muscles that contribute to the movement and positioning of the tongue, but not specifically to its ability to curl into a tube.
