Description
Abstract
Questions regarding the structure of the
inner and outer shell membranes of the chicken egg
were addressed in this study by correlating observations
from light microscopy and scanning and transmission
electron microscopy. The egg membrane had a limiting
membrane, which measured .9 to .15 pn in thickness
and appeared to be a continuous and an impervious
layer, but the shell membrane did not. Under the SEM,
each membrane was seen to be made up of severa1 fibre
layers. In the tear preparations viewed under the SEM
two layers were observed in the egg membranes and
three to five layers in the shell membrane, with an
apparent plane of cleavage between each layer. Each
fibre was made up of a central core and an outer mantle
layers. The central core was perforated by channels
which measured .O8 to 1.1 1 pn in diameter and ran
longitudinally along the length of the fibre. Between the
mantle layer and the fibre core was a gap or cleft
measuring between .O3 to .07pn. The diameter of the
fibres of the inner layer of the egg membrane ranged
between .O8 to .64pn, whereas those of the outer layer
of the same membrane ranged from .O5 to 1.11 p.m.
Fibres in the shell membrane ranged from . l l to 4.14
pm diameter.
