| Structure that separates deep and superficial perineal spaces | Perineal membrane |
| Bony landmarks between anal and UG triangles | Ischial tuberosities |
| Lateral wall of ischioanal fossa | Fascia of obturator Internus |
| Structure that forms the pudendal canal | Fascia of obturator Internus |
| Structure that separates internal and external hemorrhoids | Pectinate line |
| Lymph nodes for area superior to pectinate line of anal canal | Internal iliac, IM |
