Final answer:
The question is likely referencing the extrinsic tongue muscles, which are mylohyoid, hyoglossus, styloglossus, and genioglossus, as opposed to intrinsic laryngeal muscles. Extrinsic muscles are responsible for gross movements of the tongue, while intrinsic muscles change the shape of the tongue.
Step-by-step explanation:
Subgroups of Extrinsic Laryngeal Muscles
The two subgroups of extrinsic laryngeal muscles are not flexors and extensors, intrinsic and extrinsic, nor dorsal and ventral. The question seems to have a typo as it should refer to the tongue muscles in this context. The extrinsic tongue muscles, which include muscles such as the mylohyoid, hyoglossus, styloglossus, and genioglossus, are responsible for moving the whole tongue in different directions. In contrast, the intrinsic tongue muscles allow for changing the shape of the tongue, facilitating swallowing and speech.
The intrinsic laryngeal muscles, which were not an option provided, would be responsible for controlling sound production when we speak or sing. Understanding these differences helps clarify the muscular anatomy and its role in vocalization and tongue movement.
