The Organ-Like Nature of the Subcutaneous Fat Bodies in the Chicken ,

Morphological Aspects and the Ecological and Mechanical Consequences of Fat Deposition in Wild Vertebrates

“…In other birds subcutaneous fat is patchy; Liebelt & Eastlick (169) described it as "organ like" both in the manner of its development in the embryo and its disposition in the adult. In contrast to the weak development of adipose tissue in the mam malian fetus (2), all the 16 fat "organs" were identifiable in the chick embryo at 16 days (169). These authors recognized the following fat masses on each side of the chick: the ophthalmic body around the orbit (unlike that of mammals, it extends only a short distance over the eyeball); four distinguishable fat bodies around the neck and trachea; the large claviculo-coracoid fat body over the clavicle and anterior Annu.…”

The Lipid Content of the Subcutaneous Fat Organs of the Chick Embryo

“…Liebelt and Eastlick (1954) had shown that not only were they the largest of the fat organs, but were the first to appear. Liebelt and Eastlick (1954) had shown that not only were they the largest of the fat organs, but were the first to appear.…”
