Final answer:
Nodding your head up and down does not stimulate receptors in the utricle, it actually stimulates receptors in the saccule.
Step-by-step explanation:
The statement is false because nodding your head up and down would actually stimulate receptors in the saccule, not the utricle. The utricle and saccule are both parts of the vestibular system in the inner ear, but they respond to different types of movement. The utricle responds to acceleration in a straight line, while the saccule responds to up-and-down movements, such as nodding.
