What's the difference between hilum and ovule?

Hilum


Definition:

  • (n.) The eye of a bean or other seed; the mark or scar at the point of attachment of an ovule or seed to its base or support; -- called also hile.
  • (n.) The part of a gland, or similar organ, where the blood vessels and nerves enter; the hilus; as, the hilum of the kidney.

  • (20) At presentation, US demonstrates the tumor mass within the liver or the hepatic hilum; it allows measurement of it and defines the relationship with portal vessels, biliary tract and other important structures.

Ovule


Definition:

  • (n.) The rudiment of a seed. It grows from a placenta, and consists of a soft nucleus within two delicate coatings. The attached base of the ovule is the hilum, the coatings are united with the nucleus at the chalaza, and their minute orifice is the foramen.
  • (n.) An ovum.

Example Sentences:

  • (1) Eight-week-old virgin untreated female mice were induced to ovulate using equine chorionic gonadotropin (eCG) and human chorionic gonadotropin (hCG), and were then caged with males overnight.

  • (5) We conclude that plasma LAP measurements have little value in monitoring ovulation induction therapy.
  • (6) The mean ovulation age for the 728 abortuses was 63.4 days (range 33--109 days).
  • (7) These results strongly suggest that urinary GAGs determination is a precise method for ovulation detection.
  • (8) These findings suggest, not only that cAMP production alone is sufficient for ovulation, but also that the receptor specificity of the cAMP production is important for the number of ovulations.
