Which statement below accurately describes the anatomy of the pharynx?

Explanation

Option A is incorrect because the hard palate is formed by the maxilla and palatine bones only, not the vomer. Option B is inaccurate as the levator veli palatini forms a tendon that loops around the pterygoid hamulus to form the palatine aponeurosis, but the description lacks precision. Option C is correct since all pharyngeal constrictor muscles insert into the median raphe on the posterior wall of the pharynx. Option D is false because the upper part of the thyropharyngeus is not a multilayered muscle sheet overlapped by other constrictors.
