From the first gill arch cartilage forms square (dorsally) and the mandibular cartilage
(ventrally), constituting the rudiments of upper and lower jaw.
Coracohioideus (CH): is a paired muscle located in medial position, originated in a membrane located on the first interbranchial septum, and runs anteriorly until inserting in the hypobranchial 1, on a thick membrane just below the caudal edge of mandibular cartilage
In the control group, significant MMP2 expression was observed in the dental follicle, dental lamina, odontoblasts and enamel epithelium as well as in the Mandibular cartilage
quadratomandibularis is located in the last third of both the palatoquadrate and the mandibular cartilage
and jointly with the m.
The basihyoidean, together with the palatoquadrate and mandibular cartilages
, constitutes the mandibular arch.
