Final answer:
The superficial and deep perineal spaces are separated by the perineal membrane, which is a key anatomical structure in the perineum.
Step-by-step explanation:
The superficial and deep perineal spaces are separated by the perineal membrane. The perineum is a diamond-shaped region that includes muscles that are involved in urination, ejaculation in males, and vaginal contraction in females. The perineal membrane provides a separation between these two spaces and is a key structure in the anatomy of the perineal region.
