Slides to study:
Wharton´s jelly (99. Funiculus umbilicalis)
Loose (areolar) connective tissue (11. Esophagus)
Dense connective tissue - irregular (89. Posterior
part of the eye)
Reticular tissue (68. Lien – impregnation)
Elastic membranes (62. Aorta)
Electronograms to study:
Atlas of Cytology and Embryology #32-37.
Numbers by the slides indicate their positions in sets in Microscopic Hall,
not in online atlases. These numbers allow you to find the slides easily
and study them using a microscope when the normal classes are opened.
