Turns palms upwards

Turns palms down and inward

The pronator muscle is responsible for turning the palms of the hands down and inward. This is important for a variety of everyday activities such as holding objects and rotating the wrists. Option A is incorrect because it describes the function of the supinator muscle, which turns the palms upwards. Option C is incorrect because the function of the flexor muscles is to curl the fingers. Option D is incorrect because the function of the frontalis muscle is to raise the eyebrows. By process of elimination, we can determine that the pronator muscle is the only muscle that performs the correct function described.
