digastric (digastrik)

and n. trique Pg. It. digastrico, II. n. A muscle of the lower jaw: so called because in man it has two bellies. In its generalized condition it is a principal depre or of the lower jaw, opening the mouth and antagonizing the temporal and ma eteric muscles. It arises from the back part of the skull, and is inserted into the mandible. In man and many other animals (though not in most) it becomes digastric or double-bellied, the intervening tendon being bound by an aponeurotic loop to the hyoid bone, and the muscle thus becoming an elevator of the hyoid as well as a depre or of the jaw. It arises from the digastric groove of the mastoid, and is inserted into the symphysis ment i. With the lower border of the jaw its two bellies, which meet at an angle, bound the surgical triangle of the neck known as the submaxillary space. digastric us (di-gas'tri-kus), n.; pl. digastric i (-si). [NL.: see digastric.] In an at., the digastric muscle. dig by (dig'bi), n.; pl. digbies (-biz). A smoked herring exported from the town of Digby in Nova Scotia; a Digby herring.
