What's the difference between subzonal and umbilical?
Subzonal
Definition:
(a.) Situated under a zone, or zona; -- applied to a membrane between the zona radiata and the umbilical vesicle in the mammal embryo.
Example Sentences:

(19) The existing experience on micromanipulation of gametes (zona-opening procedures, subzonal sperm insertion, and sperm microinjection into the ooplasm) has also demonstrated the clinical usefulness in assisted fertilization, suggesting a possible selective application of various micromanipulation techniques and their combinations in male infertility.
(20) The relative suppression in the subzones was as strong as in adult cells.
Umbilical
Definition:
(n.) Of or pertaining to an umbilicus, or umbilical cord; umbilic.
(n.) Pertaining to the center; central.
Example Sentences:
(1) Direct fetal digitalization led to a reduction in umbilical artery resistance, a decline in the abdominal circumference from 20.3 to 17.8 cm, and resolution of the ascites within 72 h. Despite this dramatic response to therapy, fetal death occurred on day 5 of treatment.
