Which muscle retracts the tongue during swallowing?
Answer: Styloglossus
The styloglossus retracts and elevates the tongue, originating from the styloid process of the temporal bone.
The uvula is a muscular projection formed primarily by which muscle?
Answer: Musculus uvulae
The musculus uvulae is the intrinsic muscle within the uvula that shortens and elevates it during velopharyngeal closure.
Which articular disc is found within the TMJ?
Answer: Fibrocartilaginous disc
The TMJ contains a fibrocartilaginous disc that divides the joint into upper and lower compartments.
The tensor veli palatini muscle is innervated by which nerve?
Answer: CN V3
The tensor veli palatini is innervated by the mandibular branch of the trigeminal nerve (CN V3), unlike most palatal muscles.
In a typical adult, how many teeth are in the permanent dentition?
Answer: 32
The complete adult permanent dentition consists of 32 teeth, including four third molars (wisdom teeth).
Which bony landmark on the hard palate is important in assessing tongue rest position?
Answer: Incisive papilla
The incisive papilla, just behind the central incisors, marks the 'spot' zone where the tongue tip should rest in correct posture.
The levator veli palatini muscle primarily functions to do what during swallowing?
Answer: Elevate the soft palate
The levator veli palatini elevates the soft palate to achieve velopharyngeal closure, preventing nasal regurgitation during swallowing.
