Jane jumps out of bed to the sound of the alarm clock. As she reaches her feet, she feels very dizzy for a few seconds. As her system readjusts to her standing, she begins to regain her sense of balance. The source of Jane's dizziness is probably in the:

A) vestibular senses
B) skin senses
C) olfactory senses
D) papillary senses

The vestibular senses are responsible for our sense of balance and spatial orientation. As Jane felt dizzy upon standing, it suggests that her vestibular senses were momentarily disrupted as her body adjusted to the change in position. The skin, olfactory, and papillary senses are not directly related to balance and are therefore less likely to be the source of her dizziness.
