The lesser pelvis (or true pelvis) is that part of the pelvic cavity which is situated below and behind the pelvic brim.
Its bony walls are more complete than those of the greater pelvis.

The pecten pubis or pectineal line of the pubis is a ridge on the superior ramus of the pubic bone.
The pecten pubis forms part of the pelvic brim.
Lying across it are fibers of the pectineal ligament and the proximal origin of the pectineus muscle.

The pubic symphysis is the midline cartilaginous joint uniting the superior rami of the left and right pubic bones (pubis). It is located anterior to the urinary bladder and superior to the external genitalia; for females it is above the vulva and for males it is above the penis.
