Posteriorly, the superior ramus of the ischium forms a large swelling, the tuberosity of the ischium (or ischial tuberosity or Tuber ischiadicum in Latin, also known as the sitz bone, or as a pair the sitting bones).[1] It marks the lateral boundary of the pelvic outlet.
When sitting, the weight is frequently placed upon the ischial tuberosity.[2] The gluteus maximus covers it in the upright posture, but leaves it free in the seated position.[3]

Divisions[edit]
The tuberosity is divided into two portions: a lower, rough, somewhat triangular part, and an upper, smooth, quadrilateral portion.
- The lower portion is subdivided by a prominent longitudinal ridge, passing from base to apex, into two parts:
- The outer gives attachment to the Adductor magnus
- The inner to the sacrotuberous ligament
- The upper portion is subdivided into two areas by an oblique ridge, which runs downward and outward:
- From the upper and outer area the Semimembranosus arises
- From the lower and inner, the long head of the Biceps femoris and the Semitendinosus
