JAW

It is an odd bone that contains the lower dental arch. It consists of a horizontal portion, the body, and two perpendicular portions, the branches, which join the body at an almost right angle.

Body

Outer Face

 Mentonian Lump & #8211; triangular eminence

 Mentonian Symphysis (Anthropometric Point) & #8211; soft crest on the midline

 Mentonian foramen & #8211; depression on either side of the symphysis. Vessel and mentonian nerve passage

 External Oblique Line

Inner Face

 Mentonian Spine & #8211; pair of pimples near the symphysis

 Digastric Fossa & #8211; just below the mental spines

 Sublingual Fossa & #8211; above the milohyoid line

 Submandibular Fossa & #8211; below the milohyoid line

 Myohyoid Line (Internal Oblique) & #8211; next to the symphysis and heads back

Borders

 Superior or Alveolar & #8211; receives the sixteen teeth of the lower dental arch

 Bottom

Branches

They have two faces, four edges and two processes:

 Side Face & #8211; features oblique ridges for masseter muscle insertion

 Medial Face & #8211; presents the following structures:

 Mandibular foramen & #8211; passage of inferior alveolar vessels and nerve

 Myohyoid Groove

 Jaw Tongue & #8211; prominent ridge above the milohyoid groove

 Lower Edge & #8211; lies the angle of the jaw

 Back Edge & #8211; is covered by the parotid gland

 Anterior Edge & #8211; continues with the oblique line

 Top Edge & #8211; has two very important processes: Process Coronoid and Condylar process (articulates with the articular disc of the temporomandibular joint & #8211; TMJ). Between these two processes we find the jaw notch.

THE Jaw hinges with two bones: Temporal (2).
