The Inferior Ramus of the Ischium ( ascending ramus) is the thin flattened part of the Ischium, which ascends from the Superior ramus, and joins The obturator foramen is the hole created by the Ischium and pubis bones of the Pelvis through which nerves and muscles pass

Surfaces
Its anterior surface is rough, for the origin of muscles—the Gracilis along its medial border, a portion of the Obturator externus where it enters into the formation of the obturator foramen, and between these two, the Adductores brevis and magnus, the former being the more medial. The Gracilis ( Latin slender is the most superficial muscle on the Medial side of the Thigh. The obturator externus muscle is a flat triangular muscle which covers the outer surface of the anterior wall of the Pelvis. The obturator foramen is the hole created by the Ischium and pubis bones of the Pelvis through which nerves and muscles pass The adductor brevis is a muscle in the thigh situated immediately behind the Pectineus and Adductor longus.
The posterior surface is smooth, and gives origin to the Obturator internus, and, close to the medial margin, to the Constrictor urethrae. The obturator internus muscle originates on the medial surface of the Obturator membrane, the Ischium near the membrane and the rim of the pubis. The urethral sphincter is a collective name for the Muscles used to control the flow of Urine (micturition from the Urinary bladder.
Borders

The lateral border is thin and sharp, forms part of the circumference of the obturator foramen, and gives attachment to the obturator membrane. The obturator foramen is the hole created by the Ischium and pubis bones of the Pelvis through which nerves and muscles pass The obturator membrane is a thin fibrous sheet which almost completely closes the Obturator foramen.
