Final answer:
The soft tissue landmark covering the median palatine suture is the soft palate, a muscular fold that is involved in swallowing and separates the oral and nasal cavities.
Step-by-step explanation:
The soft tissue landmark that covers the median palatine suture is the soft palate. The soft palate is a mobile fold of muscle that can be manipulated for functions such as yawning and swallowing. The hard palate, which forms the anterior region of the roof of the mouth, is the bony structure that ends in the posterior oral cavity where the tissue becomes the fleshier soft palate. The median palatine suture is located on the roof of the mouth and is formed along the junction where the two halves of the palatine bones meet.
The uvula is a fleshy extension of the soft palate that is involved in the function of swallowing and speech, and while it is in the proximity of the median palatine suture, it does not cover it. The palatine tonsils are clusters of lymphoid tissue located at the lateral margins of the oral pharynx, between the palatoglossal and palatopharyngeal arches, and are thus not in direct association with the median palatine suture.
