posterior adductor muscle

Then he noticed Oliver's big seashell and he almost ruptured a posterior adductor muscle.

On the inside of the valve, the posterior adductor muscle scar is large and triangular while the anterior one is long and thin.

In the animal body highlights large posterior adductor muscle development, which in individuals of sizes between 150 and 200 mm can reach a diameter of about 40 mm.

The interior of the shell is white with a broad pallial line, large anterior adductor muscle scar and smaller posterior adductor muscle scar.

The pedal ganglia, which control the foot, are at its base, and the visceral ganglia, which can be quite large in swimming bivalves, are under the posterior adductor muscle.

The osphradium is a patch of sensory cells located below the posterior adductor muscle that may serve to taste the water or measure its turbidity, but is probably not homologous with the structure of the same name found in snails and slugs.

Two identifying features are that the posterior adductor muscle is positioned some one and a half times its own length from the pallial sinus, and that the muscle that retracts the foot is posterior to the insertion point of the ligature.
