ligamental造句

• The word " trough " in the common name refers to the fact that all " Mactra " shells have a large ligamental pit at the hinge line, which in life contains a large internal ligament.
• The ventral condyle is not linked to the ventral supracondylar tubercle by a ridge; as a result, the facies between the ventral supracondylar tubercle and the ventral condyle are flat rather than housing a broad fossa, and the ventral epicondyle has smaller ligamental attachment points and is smaller than other " Pelecanoides ".
