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
