The function of the supra-renal bodiesis quite unknown. It is noticeable, how-ever, that in Addisons disease (bronzedskin) which is perhaps primarily anervous affection, these glands have fre-quently, but not invariably, been foundto be diseased. Owing to the injury toadjacent abdominal organs extirpation ofthese organs is often, although not always,fatal. Brown-Sequard thinks they maybe concerned in preventing the over-production of pigment in the Fig. 95. Section of a human supra-renal capsule—a, capsule; b, gland cells of thecortex arranged in columns; c,glandular net-work of the medulla;d, blood-vessels. V. Hypophysis Cerebri—Coccygeal and Carotid Glands. The hypophysis Cerebri, or pituitary body, consists of an anterior lower orlarger lobe partly embracing the posterior lower or smaller lobe. These two lobesare distinct in their structure and development. The posterior lobe is a part ofthe brain, and belongs to the infimdibulum. The nervous elements are displacedby the ingrowth of connective-tissue and blood-vessels. The anterior portionrepresents an inflected and much-altered portion of ectoderm, from which it isdeveloped. It contains gland-like structures, with connective-tissue, lymphaticsand blood-vessels, the whole being surrounded by a capsule. According to Eckerand Mihalk
