The present results suggest that the skull form of the Caspian seal has changed morphologically from its ringed seal-like ancestors, and suggest that the evolutionary strategy of the muscles of mastication in the Caspian seal is principally consistent with that of the Baikal seal.H....
The respiratory system is composed of two divisions - the conducting zone, which brings air into and out of the body, and the respiratory zone, which facilitates gas exchange with the pulmonary capillaries. The conducting zone includes the nasal cavity, the pharynx, the larynx, the trachea, the...
Identify the muscles of mastication. What is the associated foramen of cranial nerve V2 (Trigeminal - maxillary)? What is the name of the muscles in the buttocks? Fill in the blank. At the base of each arytenoid cartilage is a projection called the ___. Name the outer connective tissu...
Who has given such resilience to the muscles of the stomach that it has been commissioned to digest coarse foods? And who has made the liver soft and tender to accept nutriment in purified and rectified form and function more finely than the stomach? (;an all these tasks be completed by ...
As muscles of mastication not only move the lower jaw of the rat, a 'phasic' action, but also suspend it from the cranium, a 'tonic' activity, some indication of the contribution of the major muscles to these functions has been gained from an examination of the fibre content of ...
anatomic sections, allows direct visualization of soft tissuecomponents (including disk and joint structures), allows easy bilateral assessment, allowsassessment of joint effusion and inflammation, and easily can image structures outside the joint, such as the joint capsule and muscles of mastication.Pol...
Electromyographical (EMG) activity was recorded bilaterally from the masseter and temporalis muscles of alert ferrets (Mustela putorius furo) during mastication and crushing. Electromyographic activity was also recorded during biting while a bite-force transducer placed between the carnassial teeth ...
But in complete denture wearers, computed tomographic study of masseter and medial pterygoid muscles have demonstrated greater atrophy and so is the reduced biting force. The sequele of this is impaired nutrition and this leads to poor and debilitated health in old age. The condition becomes ...
In addition, activity of the anterior temporalis is not consistently higher than the posterior temporalis during incision. The data indicate relatively greater activity of anterior temporalis compared to other muscles during isometric biting on the postcanine toothrow. This may be due to decreased ...
It is followed by a propalineal anterior displacement relying heavily on the action of the M. pterygoideus. The fiber lengths of the several muscles reflect the extent of shortening. The most obvious modification appears in the M. pterygoideus, which contains a central slip of pinnately ...
