• A. Hyoglossus
• B. Palatoglossus
• C. Styloglossus

Answer 1

The correct option is D All of the above

The eight muscles of the human tongue are classified as either intrinsic or extrinsic. The four intrinsic muscles act to change the shape of the tongue and are not attached to any bone. These are superior longitudinal muscle, inferior longitudinal muscle, vertical muscle, and transverse muscle. The four extrinsic muscles act to change the position of the tongue and are anchored to bone. These are genioglossus, hyoglossus, chondroglossus, styloglossus and the palatoglossus.

Thus, the correct answer is option D.
