Normal Lip Anatomy

•Upper lip
•Lower lip
•Vermillion border
–sharp demarcation between the red colored part of the lip and the adjacent normal skin of the face
•Philtrum
–The philtrum is the midline groove in the upper lip that runs from the top of the lip to the nose.
•Labial commissure
–The commissure is the corner of the mouth, where the vermillion border of the superior labium (upper lip) meets that of the inferior labium (lower lip).

•Mandibular labial mucosa

•Maxillary labial mucosa

•Fordyce’s Granules
–small raised, yellow-white, skin-colored, or pale red bumps or spots that appear on the lips.
 

6


•Buccal mucosa
–Lining of the lips and cheek
 

7


• Parotid papilla
–a small elevation of tissue that marks the opening of the parotid duct on the inner surface of the cheek, near the second molar

‘Milking’ the parotid gland’

•Pterygomandibular Raphe
–The pterygomandibular raphe is the tendinous intersection, or seam, between the superior pharyngeal constrictor and the middle portion of the buccinator

Linea Alba, if present

•The Hard Palate
–the roof of the mouth, consisting of an anterior     bony portion (hard palate)

•The Soft Palate
–the posterior muscular portion (soft palate) that separate the oral cavity from the nasal cavity.

•Palatal vibrating line
–Say ‘ahhhhh’ and watch for the palatal vibrating line that demarcates the hard from the soft palate

•Mandibular Tori








•A tori is a kind of bone growth or bump on the floor of the mouth, or the roof of the mouth (palate). It means you have a completely benign (harmless) bone growth, which is very common. Growth is very slow, and they are considered a normal anatomical feature.

•Oropharynx
–The oropharynx lies behind the oral cavity, extending from the uvula to the level of the hyoid bone

•Tonsils
–small mass of lymphatic tissue located in the wall of the pharynx at the rear of the throat

•Retromolar pad
–A cushioned mass of tissue, frequently pear-shaped, located on the alveolar process of the mandible behind the area of the last natural molar tooth.

•Lingual tonsil
–rounded masses of lymphatic tissue that cover the posterior region of the tongue
–They are located on the dorsal surface at the base of the tongue

 

22


•Lingual frenum
–The lingual frenulum is a small fold of mucous membrane extending from the floor of the mouth to the midline of the underside of the tongue.
 

23


•Lingual veins

•Lingual varicosities
–Dilated and tortuous veins of the tongue.
–Red to purple clusters found on the lingual and lateral surfaces of the tongue

•Floor of the mouth
–Watch the saliva flow
–Observe the salivary ducts

•Palpate the floor of the mouth
–What do you feel?
