have
developed to the practical exclusion of the other elements. It is found in
the ligamenta subflava, in the vocal cords, in the longitudinal coat of the
trachea and bronchi, in the inner coats of-the blood-vessels, especially the
larger arteries, a.nd to a very co.nsiderable ex~ent in t~e thyro-hyoid,
crico-thyroid, and ~tylo-hy~id ligaments. It IS also found In the ligamentum
nuchre of the lower animals (FIg. 614). In some parts, where the fibres are
broad and .Iarge and the netwo.rk close, the tissue presents the appearance
of a membrane, with gaps or perforatIOns corresponding to the intervening
space. This is to be found in the i~ner coat of the arteries, and to it the
name of fenestrated
membrane has
been given by Henle. The yellow elastic fibres remain unaltered by acetic
acid.
