Urine draining from the umbilicus after birth

3

what umbilical ligament does the urachus form?

the MEDIAN umbilical ligament

What umbilical ligament do the umbilcal arteries form?

the MEDIAL umbilical ligaments

What embryological structure forms the medial umbilical ligament?

umbilical arteries

6

What embyological structure forms the median umbilical ligament?

Urachus

From the apex of the bladder to the umiblicus

8

Which fontanelle is diamond shaped and which is triangular?

diamond - anterior fontanelle
triangular - posterior fontanelle

9

What are the boundaries of the posterior fontanelle?
