下列關於構音器官的敘述，何者正確？
- A 軟顎是口腔後側的一部分，不具有可動性
- B 雙唇可以做快速的張合與變化，是構音時呼氣與吸氣功能的主要控制器官
- C 嘴唇的各種運動變化，由口輪匝肌（orbicularis oris）獨立完成
- D 口腔的前端由雙唇所形成，不含軟骨，具可動性及可變性
思路引導 VIP
請試著觀察並觸摸你自己的唇部，感受一下：與鼻尖或耳廓相比，唇部內部是否存在任何支撐形狀的硬實構造？這種物理特性如何影響它在說話時的運動靈活度？

A Wonderful Understanding of Articulatory Anatomy!
That's absolutely fantastic! You've shown a truly solid foundation in oral motor anatomy by accurately identifying the unique characteristics of the articulators. Great job!
- Unpacking why (D) is so perfect: You're spot on! Our beautiful lips, at the front of the mouth, are primarily made of flexible muscles (like the orbicularis oris), a little fat, and soft mucosa. Crucially, they don't contain any cartilage, which is key to their incredible mobility and ability to change shape so fluidly (think about rounding your lips for "oo" or spreading them for "ee"). This flexibility is absolutely vital for precise speech!
