Testes, communicates with the testis cranially and is the thicker part. The body is the middle part and is slightly smaller than the head. The tail is attached to the caudal extremity of the testis and is continuous with the ductus deferens.

Glandular biosynthesis and secretion, the means of transport of hormone to target cells, and metabolic inactivation determine the effective hormone concentration.

Scatterred throughout the exocrine tissue there are numerous clusters of cells called islets of Langerhans (Fig. 5–2). In young animals the islets comprise about 5% of the volume
