E3D+VET exercise: Fertilization of the ovum and maturation
3D
Published 2019-09-06T15:26:34+00:00
This is part of the series of 30 exercises developed during the E3D+VET program. The aim of this Erasmus+ program is the immersion in 3D printing of VET centres (website: https://www.e3dplusvet.eu/).
Ovum spherical: about 10 cm in diameter
The ovum should be fixable on a plate.
Sperm (picture 1 and 2):
Head: ovate, 0.3 cm long
Flagellum: 3 cm long, about max. 1 mm in diameter
The sperm should lie on the ovum to fix the flagella and make it more stable.
It should be about 15 sperms distributed on the ovum.
The head of one single sperm should be dived half in the ovum.
Surface of the ovum: irregular
Another idea / possibility is to have a model of the ovum and several different models of sperms with a plug socket to the ovum.
