    Study Notes

    Sublingual Gland

    • Projects up into the mouth, producing a low fold of mucous membrane called the sublingual fold (plica semilunaris)

    Hard Palate

    • No distinct information provided

    Soft Palate

    • A mobile muscular fold attached to the posterior border of the hard palate
    • Separates the nasopharynx from the oropharynx
    • Mucous membrane covers the upper and lower surfaces
    • Contains the palatine aponeurosis, a fibrous sheet attached to the hard palate
    • Palatine aponeurosis is the expanded tendon of the tensor veli palatini muscle

    Soft Palate Muscles

    • Tensor veli palatini
    • Levator veli palatini
    • Palatoglossus
    • Palatopharyngeus
    • Musculus uvulae

    Palatoglossal Arch

    • Marks where the mouth becomes the pharynx

    Palatopharyngeal Arch

    • A fold of mucous membrane behind the palatoglossal arch
    • Runs downward and laterally to join the pharyngeal wall
