Final answer:
Anxiety can affect the genitourinary system by stimulating or hindering micturition (urination). The sympathetic nervous system activation caused by anxiety can lead to increased or decreased urination. This can result in frequent urination or difficulty emptying the bladder.
Step-by-step explanation:
Anxiety can affect the genitourinary system by stimulating or hindering micturition. Micturition refers to the process of urination. When a person is anxious, their body's sympathetic nervous system is activated, which can lead to increased or decreased urination. For example, some individuals may experience frequent urination due to heightened stress levels, while others may have difficulty emptying their bladders. This is because anxiety can impact the nervous control and anatomical structures involved in the process of urination.
