The angular is a large bone in the lower jaw (mandible) of amphibians and reptiles (birds included), which is connected to all other lower jaw bones: the dentary (which is the entire lower jaw in mammals), the splenial, the suprangular, and the articular. It is homologous to the tympanic bone bone in mammals, due to the incorporation of several jaw bones into the mammalian middle ear early in mammal evolution.
Famous quotes containing the word bone:
“Sang a bone upon the shore;
A man if I but held him so
When my body was alive
Found all the pleasure that life gave:
A bone wave-whitened and dried in the wind.”
—William Butler Yeats (18651939)
