All of the following are TRUE regarding engagement of the head, EXCEPT:
The diameter of engagement is the diameter of pelvic inlet in which head engages. Once engagement occurs, the veex will be at the level of ischial spine and on abdominal palpation, either no pa or only one-fifth of the head will be palpable. Ref: Textbook of Obstetrics Sheila Balakrishnan 1st Ed, page 125-126
One fifth of the head may be palpable per abdomen
The veex will be at the level of ischial spine
The biparietal diameter has passed through the pelvic inlet
Two-fifth of the head may be palpable per abdomen
