Bones of the Visceral Skeleton Flashcards
the bones of the visceral skeleton were derived from?
the gill arches
visceral skeleton consists:
lower jaw
hyoid apparatus
bones of the lower jaw:
Mento-meckelian
Dentary
Angulo-splenial
the anterior small bone of the lower jaw
mento-meckelian
this bone unites with the other half of the lower jaw
mento-meckelian
the thin, longer portion that forms the whole middle surface of the lower jaw
dentary
the stout and most posterior part of the lower jaw
angulo-splenial
this bone articulates with the upper jaw of the skull
angulo-splenial
a flattened structure made up of cartilage except for the pair of thyroid processes at the posterior part which is a bony structure
hyoid apparatus
supports the floor of the mouth and larynx
hyoid apparatus
a pair of long, slender, horn-like cartilage arising from the anterolateral border of the hyoid
anterior cornua
the flattened, four anged, ventral cartilage of the hyoid
body of the hyoida
a pair of pointed and short processes which arise from the postero-lateral borders of the hyoid
posterior cornua
a bony prcoess arising from the middle part of the posterior margin of the bdy of the hyoid. this supports the posterior part of the larynx
thyroid processes
A pair of small lateral expansion on the anterior side of the body of the hyoid
Alary processes
