206. Jaw joint of right side, articulatio mandibularis, 



from within. 



On the medial side of the jaw joint the ligamentum sphenomandibulare proceeds 

 from above and behind, downward and forward. It arises from the spina angularis ossis 

 sphenoidalis and from the fissura petrotympanica ossis temporalis and ends with a broad 

 insertion at the lingula mandibulae. It is separated from the medial fibrous band of 

 the ligamentum temporomandibulare and from the processus condyloideus mandibulae by 

 a space through which runs the a. maxillaris interna with the veins accompanying it 

 (see page 449) and the n. auriculotemporalis. 



The ligamentum stylomandibulare (0. T. stylo -maxillary ligament) arises in 

 common with the ligamentum stylohyoideum (see p. 40) from the processus styloideus, 

 runs obliquely forward and downward and is fastened by broad attachment to the inner 

 side of the angulus mandibulae. It is only a band of the fascia buccopharyngea (sec 

 p. 247) and has nothing to do with the joint of the jaw.
