Preferred Label : tensor tympani;
Uberon definition : The larger of the two muscles of the tympanic cavity, is contained in the bony canal
above the osseous portion of the auditory tube. Its role is to dampen sounds produced
from chewing. It arises from the cartilaginous portion of the auditory tube and the
adjoining part of the great wing of the sphenoid, as well as from the osseous canal
in which it is contained. Passing backward through the canal, it ends in a slender
tendon which enters the tympanic cavity, makes a sharp bend around the extremity of
the septum, known as the processus cochleariformis[1], and is inserted into the manubrium
of the malleus, near its root[WP].;
Uberon synonym : eustachian muscle; tensor tympani muscle;
Uberon related term : tympanic muscle; M. tensor tympani;
Uberon Homology note : The division of the adductor mandibulae in the various lines of tetrapod evolution
correlates with divergences in their methods of feeding. (...) As the jaws become
stronger and their movements more complex in the line of evolution toward mammals,
the adductor complex becomes divided into several distinct muscles (temporalis, masseter,
pterygoideus, tensor tympani, tensor veli palati).[well established][VHOG];
